The project prioritises low-carbon construction with a timber structure and cladding. The natural material is celebrated within the interior of the homes, both reducing the environmental footprint and creating a beautiful, natural aesthetic. The cladding, featuring rectangular timber shingles, slim timber detailing, and weathering steel, reflects the marshland's natural character, and the form is a reminder of the long salt stores that once dotted the landscape. The project retains a surviving historic shed believed to have been part of the Roe & Stone Salt Works, a tangible link to the site's industrial past.

The design aspires to be self-sufficient in energy consumption. Innovative glass photovoltaic panels, cleverly integrated into the truncated roof ridges, capture solar energy. Shuttering minimises light spillage, protecting the surrounding habitat. Replacing flood-prone and energy-inefficient cottages, the new dwellings prioritise resilience. Elevated basements and plant zones safeguard the homes and their occupants from future floods.

The landscape design further enhances the ecological value of the site, incorporating a natural border and a wildflower meadow. This demonstrates respect for the protected marshland and its vibrant ecosystem.

The Salterns sets a commendable precedent for sustainable development in sensitive coastal environments. By prioritizing flood resilience, low-carbon construction, and a design that integrates seamlessly with the natural and historical context, it serves as an example for future developments that respect both human needs and ecological well-being. Whaleback is proud to have been a part of this innovative and forward-thinking project.
