Cullinan Studio has completed a playfully creative, light-filled cross laminated timber and brick new-build family home in Amersham, Buckinghamshire. The busy family, which includes two boys, two dogs and visiting grandparents with increasingly limited mobility, had been struggling in a flimsy, badly insulated, dark and inaccessible house with a poorly designed extension, which created a barrier to their much-loved garden.

Cullinan Studio offered a bespoke solution which met the sustainability criteria of a kit house, and ensured it was tailored to the family so that they can play out the daily life they’ve always wanted: in a spacious, naturally-lit home connected to their leafy, mature garden and surrounded by the warmth of the exposed timber structure.

Today the 30s houses are fiercely protected, with any departure from imitative Arts and Crafts form and detail frowned upon by the local authority and its planning committee. The family’s initial plans to rebuild proved challenging, but Cullinan Studio understood the priorities and passions of the family, and in conversation with local planners they have designed a new house that exceeds everyone’s expectations.

The new two-storey detached house is redolent of Arts and Crafts architecture in its well-proportioned solid forms, steep roof and palette of sturdy materials. The design ruptures the volume of a traditional pitched house, pulling it into three parts and cracking open the roof to pour light into the heart of the home. The architects have pushed and pulled the footprint of the original house to better suit the family, orientating the new house towards the garden, making it a natural extension of their home.

The main volume of the house is symmetrical in plan with an entrance hall and stairwell slicing through the centre. The recessed entrance hall is flanked by two mono-pitched volumes, which are defined by a brick base of locally sourced Chiltern brick and lime mortar topped with black stained vertical timber panels. A sweeping grey tile clay roof completes the materials palette, appearing to float over the high level eave windows which, in turn, allow views directly from bedrooms into the tree canopy while maintaining privacy towards neighbours.

The first floor has four corner bedrooms: the master bedroom and en suite bathroom, two bedrooms for the boys with a shared bathroom and ladders to high study ledges, and a guest bedroom with en suite. The eastern pitched roof slopes down to an open plan, single-storey volume containing a large ground floor kitchen and living and dining rooms. On the western side of the ground floor there is an accessible bedroom for visiting grandparents, a study and workshop. Beneath the large living area, the architects created a den in the basement for the boys to escape to.

Practice Leader Roddy Langmuir explains:

“Before we had built anything, we noticed that the family already had a favourite place in the garden, a place where the west sun swept round behind the north-facing frontage. By sliding the living room wing back into the garden we were able to catch this afternoon and evening sunshine. Free corners frame views out to the garden, allowing the family to connect to their garden and the tall trees of the street. Glimpses of changing weather and sky follow the family as they go about their day.”

Houseowner Veronica Steel, commented:

One of the key elements of the design which I get so much pleasure out of is the high-level clerestory windows which frame beautiful views of the trees and changing sky, enlivening the interior like a mural.”

Overlapping voids and double-height pine walls form a sequence of volumes so the living spaces flow together, making for a fun and sociable home. A storage wall built into the eastern stair displays the family’s books, ornaments and artwork, and mezzanine floors offer spaces for retreat with views back over across larger gathering spaces at the heart of the home.
