Duration

22 weeks from commencement to completion.

Overview

What the client wanted

Steering an extension through planning in a conservation area. David and Laura loved where they lived but with another child on the way, they only had two options: move house or invest in extending their existing home.

They did the right thing and asked friends for builder recommendations. In a conservation area with a fairly tight plot, they needed a firm which could guide them through the often complicated planning process. They wanted a firm which could project manage the entire build. Happily, they’d carried out extensive work for a family they knew well.

How we delivered it

Getting the right design to please the planning department as well as the Whites was imperative. Our architect worked through various options until we found the footprint and internal layout that would meet the family’s needs as well as the local authority’s conservation area rules and particular planning stipulations. We also steered them through the information gathering, liaison and form-filling required by Thames Water.

A single-storey L-shaped extension now wraps around the back and side of the house. It has a pitched roof with skylights that meet conservation area standards, where materials matter more than ever. We were meticulous, matching brickwork and roof tiles exactly with the existing building. Wooden sliding sash windows and stone sills fit the period property perfectly. Permeable paving on the new driveway means no rainwater runoff.

Inside, David and Laura wanted open space that suits modern family life. We took down a defunct chimney and walls, inserted steel RSJs to do the heavy lifting, and created a light, open family area that takes in the kitchen our interiors team sourced and fitted, and dining and living space. To the side, a guest suite gives visitors a spacious bedroom and en-suite, while a utility room with bespoke joinery offers masses of organised storage to make daily life really clean and easy.

We helped David and Laura choose the wooden floors that feature throughout downstairs, warm beneath the feet thanks to new underfloor heating, cylinder and boiler. We sourced wooden bifold doors that open up onto their lovely back garden, and of course all the tiles for the guest en suite and utility room. The skylights flood the space with natural daylight, while in the evening our careful lighting design creates just the right atmosphere.
