Cripps Avenue

Stonewater aimed to develop affordable housing on the challenging site, which required substantial preparation due to the presence of concrete pads, tanks, pits and contamination. They sought a solution that would not only provide new homes but also improve living conditions for 100 residents, ensuring lower maintenance costs and future revenue savings for reinvestment into other projects. The housing association wanted to set a benchmark in sustainable residential construction and achieve high levels of community satisfaction.

The site was steep and long, with a change in levels of 14m, and surface water also required careful managing. Our assistance included extensive site preparation, such as the removal of contaminants and the crushing and reuse of materials for ground stabilisation. We thoroughly investigated the sub-soil conditions, leading to the implementation of a piled slab foundation necessary due to the chalk sub-soil extending up to 20m deep.

The site was challenging due to contamination and the risk of solution features, which can occur in chalky soil. Solution features are caused by slightly acidic surface water runoff, which dissolves the underlying chalk and forms caverns prone to subsidence. Modular construction specialist Boutique Modern was prepared with ways to address any caverns, but thankfully none were found.

We employed a fabric-first approach and conducted carbon analysis to ensure compliance with fire regulations and structural longevity for the refurbishment of a building. We also made improvements such as fire-rated door sets, thermally efficient windows, and LED lighting systems, which resulted in lower energy bills for residents.

Community engagement was a key part of the project, despite delays caused by the pandemic. Baily Garner worked with residents to ensure work could continue safely and addressed concerns from the Tenant Residents Association. This led to high satisfaction levels, averaging 92% at the project’s completion.

The Cripps Avenue development was completed in February 2023, meeting Stonewater’s affordable housing requirements and setting a benchmark for sustainable construction and resident engagement. Baily Garner’s project management, environmental standards, and commitment to the community ensured the successful integration of modern construction techniques with environmental quality controls.
