RIBA Presidents Medals 2009 - Shortlisted ProjectCayton Bay Surf School – Alex Hargreaves
The brief called for a scheme to expand an existing surf school business, which has two sites based in Scarborough and Cayton Bay, both of which are on the North Yorkshire coast. The project is based at Cayton Bay which has become well known recently due to its high susceptibility to coastal erosion. The site is a large man-made plateau, fortified by a seawall made from local stone, brick and concrete. The plateau and its sea wall protect a Victorian pump house, outbuildings and the unstable hill behind it.
The main premise of the project is based upon Cayton Bay’s susceptibility to coastal erosion. The cliffs either side of the plateau are made of boulders encased in clay formed during the last ice age. As the cliffs recede through coastal erosion, these boulders are released on to the beach and can be collected by resident surfers and craftsmen who shape and form them into building materials for the site. The buildings develop in a phased programme as more material is released, collected and shaped.
“As the cliffs recede the building grows”.
Research into “green” alternatives to petrochemical foam surfboards, highlighted a sheet material lattice structure used by some manufacturers. Adapting this lattice form lead to the development of a second modular structural element used in the fabric of the building, that could fulfil a number of functions.
Other “found” materials enriched the project, reusing driftwood, the spring on the site and the health benefits of bathing in heated seawater. Energy requirements were met by a Micro CHP based on site, using waste from the site and workshop, the small coppiced wood nestled in between the protective walls and a heat recovery system running through the lattice structure and surrounding hillsides.
In answering the brief, factors such as the retention of the original plateau form were explored, as were directing views toward the three main surf spots in the bay and rewarding visitors with views of the bay as they travelled further into the site.
Expanding on the brief meant introducing new features, which would ensure the business remained profitable year round. “Spa” features, the site workshop and Micro CHP allowed the business to generate income independently. The site was also intended to provide employment and re-training for a local workforce. It was felt that similar projects could help the renaissance of Britain’s declining coastal towns.
The reclaimed or found processes on the site are inherently green, not because the sole function of the site is to be an exemplar of green building, but as evidence of how green can be quiet and unseen and should be incorporated at all levels throughout a building where possible. The structures, processes, materials, historical links and connection with local culture help to anchor the building to its location at multiple points.
