                                                  Background
Aerial view of Swansea                            The Tall Buildings Strategy is one of a series of interrelated initiatives
                                                  that the City and County of Swansea are developing to improve the
                                                  long-term performance of the city and the quality of the built and
                                                  natural environment for residents, visitors and businesses.

                                                  The other initiatives are:

                                                  •	   City Centre Strategic Framework (Roger Tym &Partners);
                                                  •	   Swansea Bay Strategy (White Young Green);
                                                  •	   Tawe Riverside Corridor (Hyder Consulting); and,
                                                  •	   Swansea Tourism Strategy (Stevens & Associates).

                                                  These studies will provide a framework to guide future development
                                                  and enhancement, and compliment existing regeneration initiatives
                                                  in the City of Swansea.

                                                  Swansea is not a tall city, however opportunities exist for tall
                                                  buildings. Until recent times the tall buildings in Swansea have been

                                                  Swansea has grown considerably over the years with many new
                                                  buildings and future plans for expansion. Recent planning approvals
                                                  now include Merdian Quay, a 29-storey residential tower with
                                                  restaurant and viewing tower at the top, and Aurora Tower, a 14-
                                                  storey building at Swansea Point.

                                                  Swansea is now undergoing a renaissance of development and
                                                  pressure is growing for greater intensity of development, which has
                                                  prompted the need for a Tall Buildings Strategy to guide the growth
                                                  of the city.

                                                              Policy background
                                                              This strategy has been produced in response to national planning

                                                              by the Commission for Architecture and the Built Environment

                                                              authorities to identify suitable locations where tall buildings are
                                                              and are not appropriate, in areas where such developments are a
                                                              possibility.

                                                              The growing need for a Swansea Tall Building Strategy has
                                                              arisen from increased developer interest, a growth in tall building
                                                              applications and growing acceptance that a coherent approach to
                                                              future tall building proposals in the city is required.

                                                              Following consultation, the City and County of Swansea adopted the
                                                              strategy in October 2008. The strategy will form a key development

                                                         The Strategy
City Centre Facilities Plan                              The Strategy considers the urban context of the city, the role of
                                                         tall	buildings	and	identifies	appropriate	places	where	tall	buildings	
                                                         may be located. The strategy sets out advice on the design of tall
                                                         buildings and the supporting information that is required by the City
                                                         and County of Swansea to be submitted with a planning application.

                                                         The	aim	of	the	Strategy	is	not	to	be	site	specific,	nor	to	establish	
                                                         appropriate building heights, but to identify areas of opportunity.
                                                         It focuses on the responsibility of the applicant to justify their tall
                                                         building application, encouraging high quality design.

                                                         The Strategy recognises that tall buildings can have a positive role in
                                                         the city, but that they must relate to the context of the area, be well

                                                         and be close to supporting uses and infrastructure.

                                                         City Centre
                                                         The Tall Buildings Strategy is applicable to the whole of the City
                                                         and County of Swansea. The main thrust of the Strategy, however,
                                                         focuses on the city centre where tall buildings are considered more
                                                         physically and economically viable. It also considers other areas
                                                         including the university and SA1 waterfront development.

Topography                                             The topography of Swansea is an important factor to be considered
                                                       in determining the appropriate location for tall buildings. The

                                                       feature. Mayhill and Kilvey Hill form the upper ridgeline of Swansea’s
                                                       rolling hillside and the distinct edges of the lower Swansea Valley.
                                                       The valley creates a distinct break in the skyline, clearly visible from
                                                       the sea and along the western stretches of Swansea Bay.

                                                       surrounding hillsides is visible on the horizon and therefore more

                                          Existing Buildings
                                          A collection of tall buildings lies within the city centre. Prominent tall
                                          buildings include post war residential and commercial tower blocks.

                                          The	BT	Tower,	near	Swansea	Castle,	the	slab	office	block	of	
                                          Alexander House and the residential towers at Dyfatty are dominant
                                          features across the north and eastern parts of the city. The
                                          photographs illustrate how the buildings sometimes are seen against
                                          the blue-sky but from other viewpoints their impact is lessened when
                                          seen against the background hills. The larger slab blocks are very
                                          dominant and the height and width combine to create a visually
                                          intrusive element.

                                          The Swansea Sail Bridge forms a key element in the city structure,
                                          reconnecting disparate areas of the city and recent waterfront
                                          buildings include the 29-storey Meridian Gate development, the
                                          14-storey Aurora Tower and the 6 to 10-storey development at St
                                          Thomas.

                                          The Guildhall tower forms a slender civic landmark within the city
                                          structure. Comparatively, Singleton hospital and the university
                                          Campus form a clustering of tall buildings, ranging from 2 to 10
                                          storeys in height. The slab blocks are a noticeable feature along the
                                          sweep of the bay.
