We transformed a semi-detached period property in Hampstead, London into a large open-plan home, split across 4 floors.
Location: Hampstead, London
This stunning semi-detached period property used to be part of an old church, which was divided into three properties many years ago. We worked closely with the client to transform the property into an extended family home spread across four floors, complete with a unique layout and brand new bespoke basement to offer spacious open-plan living.
We introduced a basement underneath the existing ground floor by successfully excavating through the reinforced concrete floor, and underpinning all the existing foundations to create the concrete slab, and built the ground floor from timber to create a complete shell for the basement. In addition, we introduced a cavity drain membrane system to ensure the basement is fully waterproof. The new basement was then used to house a large, open plan kitchen, utility space, and downstairs WC.
We liased regularly with the client throughout the build to keep them informed of progress, and to advise and consider additional features that would add further value to the final build. They are delighted with the end result, which has completely transformed their family home for their everyday living and enjoyment.
For the ground floor, we designed and created two bedrooms (both with ensuites), which were purposefully identical in size and symmetrical.
