Feasibility Study, Concept Development, Detailed Planning Drawings, Public Consultation

KSA were commissioned by Portsmouth City Council in 2019, based on our leading reputation within the care and extra care sector, to develop plans for the comprehensive redevelopment of the former Edinburgh House residential care home that was no longer fit for purpose.


The brief required a scheme of circa 50 self-contained dwellings within a dementia friendly care ready setting that would be capable to meeting the changing needs of residents. The first facility of its kind within the city, KSA led a highly experienced design team, in collaboration with internal stakeholders from the Council, to develop a scheme for 55-units that would meet this challenge while embracing the very latest guidence and principles of the HAPPI reports.

Centred around a secure internal sensory garden courtyard, the building will be built into the sloping site and range from 2 to 3 storeys in height. Each floor comprises a central looped corridor that avoids dead end scenarios. Views out and visual cues have been incorporated to assist with wayfinding and each floor will benefit from a different interior design approach. Finished in a subtle contemporary language, the building utilising solar shading feature surrounds along its southern elevation to minimise excess solar gains and to create a strong statement within the street scene.
