The Project

James Lockyer Associates provided structural condition and contamination surveys and outline drainage proposals for four barns at this complex in support of planning applications to convert. We were subsequently retained by the new owners to work alongside their architects to full provide structural and drainage design services.

The structural design solution required careful consideration of the intended form to marry old and new, with the four old stone barns being converted to two dwellings with contemporary infill spaces to connect the structures.

With no mains drainage available, the solution adopted included soakaways for surface water and a septic tank with infiltration field for foul drainage. We carried out percolation tests to verify the initial feasibility of the scheme.
