Planning History

Full planning permission was granted in October 2023 (Ref: BH2023/00912) having received a unanimous approval at the Planning Committee in July. The application followed a rigorous process of community, stakeholder and local authority engagement to redevelop part of the Ingram Housing Estate for Brighton and Hove City Council. The design for Knoll House provides much needed affordable supported housing for people with physical disabilities and acquired brain injuries. All the dwellings will deliver wheelchair accessible independent housing.

The Design Process

Located in the Ingram Estate, an established residential community, the re-development of Knoll House proposes 28 new supported housing apartments with communal accommodation and facilities for an onsite care team. The innovative design delivers a complex programme of spaces, on a very constrained site, through a sustainable and biophilic approach. The brief required four self-contained cohorts to be bought together as a shared community in a single residential building on the site of an outdated sheltered housing building.

The linear design follows wider estate orientation and massing, sitting comfortably in the setting. The new entrance is clearly visible on the approach with an adjacent parking area. This vibrant social entrance space offers direct access to wider community growing gardens and associated social offerings. The façade’s red brick and contrasting white inset balconies reference buildings within the Ingram Estate. Whilst the elevational proportions, the white brick banding and red fluted brick details that wrap around the perimeter, re-interpret the Brighton Regency Style.

Given the needs of residents who will live in the building, an open and accessible design is key to supporting their wellbeing. Open deck access enables clear orientation to each dwelling whilst providing dual aspect dwellings throughout the design. Arranged over 3 and 4 levels, each cohort of residents is securely clustered via the stair/lift core, with a unique social space for each. The largest Cohort has access to the roof terrace, its communal space and sea views - a truly special garden opportunity.

Connections to outdoor spaces and nature will support wellbeing and provide an enjoyable place to live. The biophilic design response is evident throughout, where canopy columns and brickwork offer infrastructure for growing gardens.

Sustainability

Brighton and Hove City Council are committed to providing new low carbon homes to help meet the UK’s climate change targets. The Knoll House strategy has followed the energy hierarchy to ensure that this new development reduces carbon emissions and delivers on sustainability. The use of technologies in combination with thoughtful passive design, improved levels of insulation and improved air permeability will allow the building to achieve a reduction in carbon emissions. The proposed development is expected to reduce on-site regulated carbon emissions by 78% with SAP10 emission factors. The strategies that have been adopted include: • The re-development of a previously inefficient building into a building sustainable in design and location • Maximisation of energy and carbon dioxide emission reduction following the energy hierarchy through enhanced building fabric, low air permeability, use of MVHR and energy efficient lighting • Integration of a communal heat pump strategy to supply heating and hot water together with a photovoltaic array for additional carbon reduction • Enhance ecology and biodiversity on site, achieving Biodiversity Net Gain with associated landscaping in communal amenity spaces • Accessible allotments for growing garden opportunities are provided in the roof terrace gardens reflecting the community growing garden on site • Use of responsibly sourced materials with low embodied carbon including a green roof with integrated PV panels on the uppermost level • The potential risk of overheating will be mitigated by passive design responses including inset balconies and open deck walkway to provide shading of the apartment windows. While good daylight and sunlight levels are maintained • SuDS strategies include a below ground gravity drainage and soakaways In summary, the proposed development at Knoll House exceeds the targets set out by BHCC Policy. The sustainability measures incorporated reflect the client and design team’s aspirations in integrating sustainability measures at the heart of the design.
