Adam Knibb Architects

Based in Winchester, Adam Knibb Architects designs residential extensions and detached homes characterized by lightweight timber volumes cantilevered over transparent lower levels, seamless indoor-outdoor floor transitions, and sharp structural interventions against historic masonry. The work offers a clear reference when detailing flush deck-to-interior thresholds, dissolving mass through fully glazed corners, or integrating modern timber additions around existing brick party walls and chimney stacks.

Rear extension of Beckett House by Adam Knibb Architects showing a modern glass ground floor and timber-clad upper box against an older brick home.

Beckett House

An architectural precedent for contemporary residential extensions, illustrating how a glazed ground floor and timber upper volume contrast effectively with a traditional brick home.

What we like about this project
The upper timber bedroom volume cantilevers or aligns seamlessly over the edge of the lower transparent floor frame.

Geometry
Asymmetrical composition attaching a long horizontal glazed ground-floor volume and a vertical timber-clad upper box to the rear of a traditional brick gable house.
Facade system
Floor-to-ceiling sliding glass panels on the ground floor with flush head and sill details; vertical timber rainscreen cladding on the upper box.
Structural guess
Steel moment frames supporting the large glazed openings at the ground level with timber-frame construction above.
Spatial scale
Two-story domestic scale, balancing the original pitched roof cottage with clean modern additions.
Lighting
Dusk or twilight conditions; warm interior artificial lighting floods outward, contrasting sharply against the cool blue evening sky.
Atmosphere
Inviting and luminous, emphasizing the glowing threshold between interior living spaces and the dark garden.
Environmental context
Suburban backyard setting with mature lawn, boundary walls, and adjacent residential properties.
Spatial experience
A clear contrast between the dark, heavy traditional brick rear and the glowing, open-plan transparent interior spaces projecting onto the rear patio.
Composition rhythm
Horizontal expanse of floor-to-ceiling glass balanced by the vertical rhythm of timber boarding on the second floor.
