Progress Mews – Affordable Housing

Progress Mews in Surbiton, Surrey, is a standout example of how a highly constrained brownfield site can be successfully transformed into high-quality, affordable housing through thoughtful design, collaboration, and planning expertise. Delivered in partnership with Kingston Churches Housing Association, the scheme demonstrates how underutilised land can be reimagined to provide meaningful social value while respecting its sensitive surroundings.

 

Site Context and Challenges

Located within a conservation area in Surbiton, the site consisted of disused garages and hardstanding behind an existing Victorian property. The plot was tightly enclosed by residential gardens on all sides and featured limited access, restricted outlook, and several trees, including those protected by Tree Preservation Orders (TPOs).

As a backland development, the project also needed to address privacy, overlooking, and massing concerns while complying with local planning policies and conservation requirements.

 

Design Approach and Strategy

To unlock the site’s potential, a heritage-led, planning-informed approach was adopted, supported by in-house specialists at WWA. Early-stage consultation with residents and stakeholders played a key role in shaping the design, ensuring the final scheme responded sensitively to local concerns.

An innovative L-shaped building layout was developed to maximise space efficiency while preserving privacy and natural light. The scheme comprises a mix of single-storey and 1.5-storey elements, ensuring the development remains subservient to neighbouring buildings and avoids overshadowing.

Key design principles included:

  • Dual-aspect homes for improved daylight and ventilation

  • Private courtyards and garden spaces for each dwelling

  • Setbacks at first floor to minimise overlooking

  • Preservation of protected trees

  • Integration of electric vehicle charging points

  • Efficient use of constrained backland space

 

Housing Provision and Accessibility

The development delivers three dwellings (two 2-bedroom homes and one 3-bedroom home), all of which are 100% affordable. Each unit is designed to be fully wheelchair accessible, with level access, accessible bathrooms, and adaptable ground floor layouts.

These homes meet both London Design Guide standards and Housing Quality Indicators, ensuring long-term suitability for a range of residents, including older people and those with mobility needs.

Sustainability and Environmental Considerations

Sustainability was a key component of the design. The homes incorporate:

  • High levels of insulation to improve energy efficiency

  • Green roofs to assist with drainage and biodiversity

  • Durable, locally sourced materials to reduce lifecycle costs

  • Low-energy design principles aligned with long-term affordability

These measures contribute to reduced operational costs for residents while supporting environmental performance.

 

Planning, Heritage, and Collaboration

Given the conservation area context, the external appearance of the scheme required careful consideration. Materials such as London Stock brickwork and aluminium windows were selected to complement the surrounding architectural character.

Working collaboratively with our in-house heritage and planning consultants, the contractor, under a traditional procurement route, the team successfully balanced cost constraints with quality outcomes. Early engagement with stakeholders helped refine the design, reducing risk and supporting a smooth planning and delivery process.

The project team included multidisciplinary expertise across all RIBA stages (0–6), including structural engineers, quantity surveyors, arboriculturists, party wall surveyors, and landscape designers.

 

Project Delivery

The project was overseen by a director from inception through to completion, ensuring continuity and design integrity throughout. Construction drawings and tender packages were developed by a technical architect, with ongoing site involvement during construction to maintain quality and coordination.

 

Community Impact and Outcome

Progress Mews has delivered tangible benefits to the local community by:

  • Replacing underutilised and visually poor garages with high-quality homes

  • Enhancing the character of the conservation area

  • Providing much-needed affordable housing in an affluent borough

  • Improving communal garden space and storage for existing residents

  • Ensuring privacy and amenity for both new and existing occupants

The homes were officially opened with recognition from Sir Ed Davey, who described the development as “setting new standards for affordable social housing.”

 

Conclusion

Progress Mews demonstrates how complex urban infill and backland sites can be successfully developed through careful planning, stakeholder engagement, and design innovation. By combining heritage sensitivity with modern construction techniques and accessibility standards, the scheme delivers high-quality, future-proof homes that meet both social and environmental objectives.

This project stands as a strong example of how collaborative, multidisciplinary design can unlock the potential of constrained sites while delivering lasting value to communities.
