The scheme comprised demolishing front and rear elevations and constructing a single storey basement under the main house and a one and a half storey basement under the rear garden. A reinforced concrete roof deck was constructed and the rear garden with planting re-created above.

The substructure was constructed in sands and gravels to a maximum depth of 4.5 metres with steel trench sheets as back formwork to maintain integrity and prevent migration of subsoil.

The basement area measured 147 square metres and the contract period was thirty weeks. Works were completed generally on time and within budget.
