                                                          PLANNING INFORMATION
The planning process involves several stages.

•	 	The	planners	will	acknowledge	receipt	of	your	plans	either	to	you	or	to	Custom	Homes	if	we	are	handling	the	planning	application.	

•			The	planners	have	to	notify	neighbouring	properties	by	one	of	two	methods.		Some	councils	will	give	you	a	notice	that	has	to	be	pinned	
    up on the property in a prominent position but more and more authorities list all planning applications in the local press and on-line.

•			Your	plans	will	be	sent	by	the	council	to	all	representative	bodies	who	have	a	vested	interest	in	approving	or	objecting	to	a	planning	
    application. These involve such services as the police, fire brigade, highways and town councils.

•			If	Custom	Homes	is	handling	your	planning	application,	prior	to	the	planning	application	we	may	well	have	had	consultations	with	the	
    planners in an endeavour to offer compromises to help achieve a successful result. Not all clients will be happy to accept some of these
    compromises but because we act for you we will make recommendations, take your instructions and act on your behalf. We will also
    endeavour to keep you updated with important information. We will not bother you with minor compromises or unimportant issues.
    Some councils are beginning to charge for this service but it is usually very important to use this service.

•			If	the	land	has	no	planning	history	and	we	have	recommended	that	we	apply	for	detailed	planning	permission	rather	than	an	outline	
    application this will be on the basis that in our opinion the application stands a better chance of getting approval that way or that a
    refusal can be handled more constructively.

•			Custom	Homes	nearly	always	recommends	an	electronic	survey	to	be	undertaken	as	early	as	possible	to	ensure	we	get	the	best	from	your	
    site. This will be needed by the council for comparing ridge heights of neighbouring buildings and positions. We often have to draw a
    street scene.

•			A	provisional	planning	decision	date	will	be	set,	which	may	be	altered	due	to	workloads	and	holidays.		Remember	planning	meetings	
    are normally only once a month on average but some councils meet fortnightly and others only every six weeks. A planning application
    should take a minimum of 6 - 8 weeks from receipt of acknowledgement to a planning decision although in practice this usually takes on
    average eight to ten weeks. If approval is being given under delegated powers this could be as fast as 5 weeks.

•			Although	the	planners	have	a	statutory	right	to	deal	with	a	planning	application	within	a	given	time,	this	is	usually	flexible	if	we	are	in	
    consultation with them. Any undue pressure to speed up the handling of an application within the statutory timescale will often result
    in the plans getting a refusal. Many councils will not enter into discussions about alterations during an application.

•	 	If	a	planning	application	has	been	recommended	for	a	refusal	at	the	planning	meeting,	Custom	Homes	will	make	a	judgement	as	to	
    whether	to	withdraw	the	application	and	or	alter	it	or	leave	the	application	to	run	its	course	so	that	we	have	tangible	objections	to	
    enable you to take a case to appeal. This decision has to be made by Custom Homes and will in most cases be made after consultation
    with you.

•			Most	councils	will	allow	you	to	attend	the	planning	meeting	with	more	and	more	allowing	you	to	say	a	few	words	about	your	proposals.		
    If you would like Custom Homes to attend this meeting on your behalf and speak for you, you should agree a fee directly with the
    designer, independently of Custom Homes.

•			Following	the	planning	meeting	the	council	normally	takes	10	-	14	days	to	write	confirming	the	decision	made	at	the	planning	meeting.		
    This letter will also list all conditions that must apply following a planning approval or list reasons for refusal.

•			You	must	comply	with	the	conditions	listed	on	the	planning	approval	and	in	many	cases	we	can	help	you	deal	with	some	of	these.	Many	
    conditions are standard so do not get worried about them, ask your Custom Homes representative for advice.

•			It	is	Custom	Homes’	responsibility	to	try	in	all	cases	to	secure	planning	permission	on	a	given	site.		We	therefore	have	to	have	the	final	
    say	using	our	designer’s	experience	as	to	the	way	an	application	is	handled.		

•			Custom	Homes	can	usually	put	a	client	in	touch	with	an	appeals	specialist	if	a	planning	refusal	has	been	granted.		Fees	for	this	service	are	
    independent of Custom Homes.

•			All	councils	are	requesting	a	design	and	access	statement,	a	full	survey	showing	ridge	height	of	adjacent	properties	in	relation	to	your	
    own	property	and	both	hard	and	soft	landscaping	design	proposals.	All	of	the	these	if	required	are	extra	to	Custom	Homes	services	and	
    must be arranged by you the client.

•	 Planners	will	all	use	external	overall	measurements	for	the	purpose	of	obtaining	planning	approval,	you	should	do	the	same	for	costings.

                                           BUILDING REGULATION INFORMATION
Building regulations handled by your own designer

In the event of your own designer applying for building regulation approval Custom Homes will supply you with structural calculations for
the	Sips	Eco	panel	frame,	panel	drawings	and	if	required	a	construction	manual.		These	will	need	to	be	passed	on	to	Building	Control	or	
whoever is giving building regulation approval.

Building regulations handled by Custom Homes designer

Custom	Homes’	designers	will	endeavour	to	obtain	building	regulation	approval	on	your	site.		Custom	Homes	will	supply	building	
regulation	drawings,	frame	structural	calculations,	panel	drawings	and	all	information	required	to	approve	the	timber	frame	structure.	
In	some	cases	these	may	not	be	produced	prior	to	construction.		Many	items	can	only	be	supplied	by	you,	your	project	manager	or	your	
builder.

Amongst other items these may include the following:

•	 	Type	of	foundation	-	in	the	absence	of	a	soil	test	or	survey	it	will	be	assumed	that	foundations	will	be	1m	deep	by	600mm	wide.	Any	
    variation	to	this	will	be	for	you,	your	project	manager	or	your	builder	to	amend.	Variations	must	be	supplied	with	calculations,	if	
    required,	to	building	control	or	to	Custom	Homes	to	submit	on	your	behalf.		

•	 	Trees	and	the	effect	on	foundations	-	close	proximity	of	trees	to	the	dwelling	may	affect	the	setting	out	or	depth	of	foundations.	Refer	
    to	our	construction	manual	for	advise	on	this	subject.	Any	variation	to	this	will	be	for	you,	your	project	manager	or	your	builder	to	
    amend.	Variations	must	be	supplied	with	calculations,	if	required,	to	building	control	or	to	Custom	Homes	to	submit	on	your	behalf.		The	
    cost	of	any	surveys	or	foundation	engineer’s	calculations	and	drawings	are	not	covered	by	Custom	Homes.	

•	 Drainage	details	-	often	determined	on	site	with	Building	Control.	

•	 Soakaway	and	connection	to	foul	and	surface	water	outlets	-	often	determined	on	site	with	Building	Control.	

•	 	SAP	ratings	-	only	you,	your	project	manager	or	your	builder	can	supply	the	necessary	information	to	get	SAP	approval.		A	SAP	rating	
    assessor will need to know what type of boiler you have installed, the energy source (gas, electricity, propane, oil), type of zone valves
    installed, type of insulation installed, information about the frame (supplied by Custom Homes), etc. Custom Homes provide a SAP rating
    check-list in the welcome pack issued once planning permission has been granted and the frame has been placed on order.

•	 	Dimensions	shown	on	plans	can	be	+	or	-	5%.		Do	not	use	these	measurements	for	furnishing	purposes,	you	should	confirm	final	
    measurements on site. Measurements internally will be structural measurements and do not allow for plasterboard or battens.
    Tradesmen	will	all	use	overall	external	measurements	for	quoting	purposes.	

•	 	Brickwork	support	requiring	engineer’s	calculations	must	be	supplied	by	steel	fabricators	or	can	be	supplied	by	Custom	Homes.		The	cost	
    for	this	service	is	additional	to	Custom	Homes’	fees	and	is	not	part	of	the	contract	for	the	frame	or	it’s	components.	

Special prices for this service can be obtained from the Technical Department.

                                                   CUSTOM HOMES SIPS ECO PANELS
Custom	Homes’	SIPs	ECO	PANEL	package	has	been	developed	over	many	years	and	is	regarded	by	the	industry	as	being	one	of	the	highest	
quality	available	to	one-off	individual	builders	and	self-builders.	

There are many options available but our standard package is 119mm external walls, 194mm roof panels and internal walls are timber
frame	studs	49	x	95	@	600c/c.	Floor	joists	at	600mm	centres	or	to	suit	design.	Many	items	are	included	as	standard	by	Custom	Homes	which	
are	extra	from	our	competitors.		You	will	need	to	check	your	quotation	for	a	complete	list	of	what	is	supplied	for	your	particular	project.	
Our engineers and designers, both panel and architectural, spend some considerable time and care making sure your home goes together
as smoothly as possible. However, in the event of any unforeseen errors or misinterpretations, please contact your Custom Homes regional
manager	to	discuss	your	query.	

Although	every	effort	will	be	made	to	supply	and	erect	the	frame	to	our	best	endeavours,	some	additional	site	work	may	be	required	by	
others appointed by you, to complete the timber structures to suit your finished preference.

Pre fabricated frame structures are not finished items and should not be treated as such.

When ordering windows, doors and staircases only work from the final approved building regulation drawings and more importantly from
site	dimensions.	If	in	doubt	please	ask	the	technical	department	or	your	builder/project	manager	for	a	detailed	schedule.	

Remember - once the frame has been erected the roof has to be loaded before any external wall finishes are applied. This is to help the
frame settle.

You	must	protect	the	frame	at	all	times.	Immediately	on	completion	of	the	erection	the	frame,	the	roof	should	be	made	weather	tight	by	
your roofer to avoid water ingress to the flooring.

Insulation	materials	are	continually	being	improved.		“U”	Values	of	0.14W/m2K	and	lower	are	possible	using	Custom	Homes’	SIPS	ECO	
PANELS.

Our	standard	119mm	external	panel	using	a	specified	insulation	material	can	achieve	a	“U”	value	of	less	than	0.22W/m2K	

Our	194mm	roof	panels	using	a	specified	insulation	material	can	achieve	a	“U”value	as	low	as	0.14W/m2K	



                                                            SAP RATINGS

Custom Homes SIPs ECO PANEL construction helps ensure new homes easily meet the continually
     improving energy efficiency of all new homes as required by Government Legislation
Building	control	will	require	SAP	ratings.		Custom	Homes	cannot	supply	this	information,	as	they	will	have	no	knowledge	of	the	
information	required	by	assessors	to	produce	SAP	ratings.		The	assessor	will	need	to	know	the	type	of	boiler	being	installed,	the	energy	
source	and	the	type	and	location	of	zone	valves.	Only	you,	your	builder	or	project	manager	will	know	these.		However,	to	assist	you	a	form	
that will need to be completed by you and sent to an assessor will be sent to you at Building Regulation stage. Additional forms are
available from your local representative. The cost of having a SAP rating assessed will be covered by Custom Homes, if we have been paid
to supply Building Regulation drawings.

                                                                ERECTION SERVICE
Custom Homes are known in the trade for their superb erection service and attention to detail. Erection teams are selected and approved
for	the	quality	of	their	work,	their	personal	understanding	of	individuals’	requirements	and	the	support	they	will	offer	individuals.	

Prior to frame delivery a site inspection will be made to check site accessibility and the levels and dimension of the oversite. If everything
is satisfactory the frame will be delivered approximately 2 weeks after this inspection. Should the oversite be out of level or size then the
frame will be put on hold until the oversite is corrected by you.

Once the erection service has been completed our contracts manager will attend site and verify that everything has been carried out
satisfactorily. Should anything have been omitted he will ensure this is rectified and should he feel that additional strengthening or
bracing	would	be	advisable	he	will	put	this	in	place.		Should	he	have	any	queries	having	checked	the	plans	he	has	a	direct	link	to	the	
engineers	and	panel	designers,	as	well	as	to	Custom	Homes’	technical	department.	

Average	erection	time	will	take	about	4	-5	weeks	but	can	be	quicker	depending	on	the	size	of	property.	
Once	the	contracts	manager	has	finalised	his	inspection,	he	will	ask	you,	your	project	manager	or	your	builder	to	sign	an	erection	
completion	satisfaction	note.		You	will	not	be	asked	to	sign	for	the	structural	integrity	of	the	frame	as	Custom	Homes	will	have	dealt	with	
this	in	conjunction	with	the	engineers,	Building	Control	and	your	10-year	structural	warranty	provider.	

Custom Homes do not charge for overnight accommodation for any of their erection team, unlike most other timber frame companies.

However, if you know of good local accommodation please let your regional office know - all our erectors have been house trained. Please
do not book them accommodation.

All	external	joinery	items	will	be	temporarily	supported	for	a	short	time	by	either	your	own	or	our	erectors	awaiting	either	brickwork	
support	or	roof	battens.		Many	items	require	follow-on	trades	to	key	together	and	offer	support.		Minimise	delays	in	completing	these	jobs	
as	the	strain	on	some	of	the	materials	may	exert	too	much	pressure.		Any	remedial	work	required	due	to	delays	will	be	the	responsibility	of	
the client or his representative. Custom Homes will as always advise clients in this eventuality.

If	we	have	not	quoted	for	erection	of	the	timber	frame	then	we	will	supply	you	contact	details	for	erectors	who	can	assist	you.

                                                         GUIDE BUILD PRICES
Custom	Homes’	local	regional	office	will	produce	a	guide	build	price	for	your	total	project.		These	guide	build	prices	are	independent	of	
Custom	Homes	and	are	based	on	the	local	offices’	knowledge	of	up-to-date	costings.		Should	you	require	a	more	accurate	costing,	the	local	
office	will	arrange	for	a	quantity	surveyor	or	other	qualified	person	to	produce	accurate	costings	and	take-offs	for	all	materials	and	trades.	
You	should	agree	the	price	for	this	service	with	the	QS	before	you	commission	him.		

Guide build prices are based on initial sketch feasibility drawings and will have been based on standard materials. If drawings have been
amended	or	specifications	changed	to	suit	the	planners,	building	control	or	at	your	own	request	we	recommend	you	request	a	revised	
guide build price reflecting these changes. As an example, roof tiles may have been changed from concrete interlocking to a slate roof at
the	request	of	the	planners	or	to	suit	the	design.	Although	you	will	in	most	cases	anticipate	a	price	increase	or	price	reduction	it	is	better	to	
have an up to date guide reflecting these changes.

Custom	Homes	have	associations	with	the	major	suppliers	of	building	materials	and	can	pass	this	information	on	to	you.

1.   Self-manage -	there	are	two	principal	methods	of	self-managing	a	project;

	    	a)	Individuals	who	get	actively	involved	in	their	self-build	project.	These	clients	are	prepared	to	get	their	hands	dirty,	pouring	
      foundations, laying bricks, handling all the electrics, plumbing, etc. themselves. Although highly cost-effective, this relies on a large
      amount	of	DIY	skills	and	usually	takes	far	longer	to	construct	as	work	normally	has	to	be	fitted	in	around	a	full-time	career.	

	    	b)	Individuals	who	project	manage	the	build	themselves.	These	clients	do	not	get	their	hands	dirty	but	rely	on	sub-contracting	all	
      trades	people	and	use	their	managerial	skills	to	complete	the	project.	
      Guide	prices	quoted	for	management	services	are	a	guide	only	and	are	correct	at	the	time	of	publication.

2.   Part Project-management -	by	far	the	most	popular	and	cost-effective	method	of	construction.		A	project	manager	will	offer	support	with	
     some or all of the following services:

•	 Send	out	quotation	request	letters	on	your	behalf	
•	 Collate	quotations	and	submit	them	to	you	
•	 Discuss	quotations	with	you	
•	 Send	out	your	acceptance	letters	to	tradesmen

•	 Co-ordinate	on	site	glazing	if	required	
•	 Co-ordinate	rainwater	goods	
•	 Co-ordinate	fitting	of	external	door	frames	and	if	appropriate	hang	external	doors	

As	a	guide,	fees	for	this	service	should	start	at	6%	of	the	guide	total	build	price,	but	will	normally	start	at	£10,000	and	cover	the	construction	
of the dwelling only. It excludes any form of landscaping, drives, boundary walls or fencing.

If	you	commission	a	project	manager	for	a	part	project-management	service,	they	will	always	be	at	the	end	of	a	phone	to	assist	you	by	helping	
with	contacts	and	advice	and	if	necessary	make	a	daily	visit	at	the	rate	of	around	£350	per	day	after	they	have	completed	their	contract.

Notes on project management

Custom	Homes	may	be	able	to	supply	a	list	of	project	managers	in	your	area	who	have	put	themselves	forward	offering	their	services	to	our	
clients.	Project	managers	are	independent	of	Custom	Homes	and	you	must	make	your	own	selection.		Many	of	Custom	Homes’	regional	offices	
have	put	themselves	forward	as	being	able	to	offer	an	independent	project	management	service	to	clients	on	the	same	basis.		
Custom	Homes	are	not	party	to	any	contract	between	a	client	and	his/her	appointed	project	manager	and	therefore	cannot	get	involved	in	any	
legal	dispute.		Custom	Homes	can	advise	impartially	as	to	the	best	way	to	resolve	any	dispute	should	it	occur.	Project	managers	should	supply	
you with a copy of their professional indemnity insurance policy and may introduce you to previous clients. The problem with introductions
to previous clients is that Custom Homes probably build more large houses for individuals than most other companies and these clients do not
want to be pestered or allow people to visit their private property. However, they can usually find you a client within a reasonable travelling
distance.

In	part	project	management	but	you	must	take	on	a	certain	amount	of	responsibility.		After	all	you	are	likely	to	make	a	greater	saving	due	
to	your	involvement.		Your	chosen	project	manager	will	not	be	on	site	on	a	daily	basis.	When	you	make	daily	visits	to	site	it	is	important	that	
you check the site for security, hazards, protection of the frame and components. Ensure that the frame is covered to protect it from rain and
snow,	keep	the	site	safe	and	tidy,	sweep	off	any	rain	settling	on	the	panels	or	flooring	etc.	Remember	that	if	you	want	your	project	manager	
to cover these areas then you will have to pay a labourer to work on the site full time.

                                                       FULL PROJECT MANAGEMENT
3.   Full Project-management	-	The	fees	are	usually	10%	of	the	total	build	costs,	with	a	minimum	of	£15,000.	

	    	There	is	little	point	in	wasting	money	on	a	self-build	using	a	full	project-management	service	when	the	bulk	of	the	work	has	been	
      covered	under	the	part	project-management	service	leaving	virtually	only	the	internal	finishes	to	be	completed.		If	you	undertake	this	
      role	yourself	you	will	require	only	a	minimal	level	of	trades.		These	would	normally	be	a	qualified	electrician,	a	qualified	plumber,	a	
      second-fix carpenter, plasterboard fitter (tacker) and possibly a plasterer (although the tacker and plasterer is likely to be the same
      person).

In	addition	to	the	part	project	management	service	listed	above	the	following	services	are	offered	for	full	project	management	services:	

•	 Co-ordinate	installation	of	plumbing	
•	 Co-ordinate	installation	of	electrics	
•	 Co-ordinate	installation	of	insulation	
•	 Co-ordinate	installation	of	plasterboarding	
•	 Co-ordinate	plasterers	
•	 Co-ordinate	second	fix	joinery	
•	 Co-ordinate	installation	of	your	chosen	sanitaryware	
•	 Co-ordinate	installation	of	your	chosen	kitchen	
•	 Co-ordinate	wall	and	any	floor	tiling	chosen	by	you	
•	 Co-ordinate	painting	internally	and	externally	
•	 Arrange	for	final	inspection	by	building	control	
•	 Visit	site	as	often	as	they	feel	necessary	
•	 Arrange	for	final	inspection	by	structural	warranty	supplier	

The above fees cover the construction of the new dwelling only and exclude any form of landscaping, drives, boundary walls or fencing
(subject	to	your	negotiations).

     may	require	and	items	that	he	has	not	quoted	for.	

Notes to project managers’ and builders’ services

Custom Homes may be able to supply a list of builders in your area who have put themselves forward offering their services to our clients.
Builders	are	independent	of	Custom	Homes	and	you	must	make	your	own	selection.		Many	of	Custom	Homes’	regional	offices	have	put	
themselves forward as being able to offer an independent main contractor (builder) service to clients on the same basis.

Custom Homes are not party to any contract between a client and his/her appointed builder and therefore cannot get involved in any legal
dispute. Custom Homes can advise impartially as to the best way to resolve any dispute should it occur. Builders should supply you with a
copy of their professional indemnity insurance policy and may introduce you to previous clients.

                                                          IMPORTANT ADVICE

                                                Please take note of the following:
•	   DEMOLITION - If you are proposing to replace an existing dwelling - do not demolish the existing building until after planning has been
     granted	and	you	have	received	the	decision	in	writing.		You	may	lose	your	permitted	development	rights.	
•	   DEMOLITION	-	Councils	may	require	6	weeks	notice	of	any	proposed	demolition	on	site.	
•	   DEMOLITION - Contact utility companies for timescales for disconnection of services.
•	   DEMOLITION - If you have a small site remember the Party Wall Act, designed to protect your neighbours. Contact administration
     office for further advice.
•	   	SETTING OUT THE SITE - Do not set out the foundations until receipt of setting-out drawings (FLP) from Custom Homes.
•	   BEAM & BLOCK OVERSITE	-	Only	order	the	beam	&	blocks	from	the	setting-out	drawings.	You	may	require	additional	foundations	for	
     this slab as well as those shown on our FLP.
•	   	INTEGRAL/ATTACHED GARAGE - Ensure garage floor is lower than the main house or has a drainage channel (see Construction Manual).
•	   PROTECTING YOUR TIMBER FRAME	-	Ensure	the	timber	frame	is	made	watertight	as	quickly	as	possible.		Do	not	allow	water	to	settle	
     for long periods on your timber flooring. Do not carry out internal finishing off trades until the frame has been allowed to recover from
     any excessive moisture.
•	   INSULATION - Do not insulate the cavity (see Construction Manual). Remember to fit vapour barrier to external walls and wet rooms
     (see Construction Manual).
•	   ROOFING - Ensure the roof has been loaded with roof tiles prior to laying of face brickwork.
•	   CAVITY - Avoid closing the cavity off below DPC too early. If facing brickwork has to be constructed up to DPC prior to the panels being
     erected, ensure that there is a minimum 60mm cavity clear cavity. Ensure this is continued throughout the height of the building.
•	   FACING BRICKWORK - Ensure the correct gauging from foundations to head of window frames before starting work and to underside of
     soffit and fascia or gable ladders to avoid cut bricks. Also ensure correct detailing under windows and use of correct timber frame brick
     ties	(see	Construction	Manual).		Ensure	correct	use	of	cavity	trays	and	lintels.		Ensure	adequate	weep	holes	at	DPC	and	above	lintels.	Ensure	
     allowance has been made for differential movement.
•	   TILE HANGING/RENDER - If tile hanging or rendering onto mesh, ensure battens have been fitted correctly against the Sips panels (see
     Construction Manual).
•	   JOINERY	-	Ensure	external	joinery	is	protected	by	damp	proof	membrane.	
•	   BUILDING CONTROL - Ensure regular inspections are carried out by Building Control. They should be treated as a friend and advisor.
     If they are still awaiting some building regulation detailing which they have brought to your attention, which is not unusual, please
     contact Custom Homes for advice.
•	   	TRADESMEN - Try to avoid paying day rates for tradesmen. Agree fixed rates wherever possible. Do not pay in advance but do pay
      promptly	because	tradesmen	are	self-employed.		Seek	recommendations	and	see	examples	of	previous	work.		Keep	contracts	as	simple	
      as	possible	covering	the	work	you	want	them	to	perform	to	avoid	increased	costs	when	quoting.		Many	follow-on	tradesmen	try	to	
      blame	previous	tradesmen	for	errors,	this	is	commonly	done	to	try	and	increase	their	price.		Major	developers	will	not	entertain	this	but	
      individuals	find	it	harder	to	stop.		Speak	to	your	project	manager	before	agreeing	anything.	
•	   ELECTRIC SOCKETS & SWITCHES - Ensure these are fitted at the correct height to meet current regulations and that switches in wet
     rooms also comply. If a vapour barrier is punctured, ensure it is repaired correctly.
•	   	EXTRAS -This is your house so do not compromise extras but try to avoid changing your mind at the last minute. Extras work out
      expensive. Negotiate and confirm extra-over price agreements.
•	   INSURANCE	-		Ensure	adequate	insurance	cover.		Check	tradesmen’s	insurance.		Follow	health	and	safety	rules.		Always	keep	a	site	tidy.	
     Ensure secure storage facility is on site. Items on building sites are highly covetable.
•	   DELIVERIES - Always ensure that someone is on site to receive deliveries. When signing a POD (proof of delivery note) always check
     that delivery is correct and if necessary call on the relevant tradesmen for advice. Ensure shortages are notified immediately.
This list is not exhaustive but covers some of the questions and problems often encountered by self-builders.
