Beche Road Loft Extension
Beche Road Loft Extension, Cambridge
A reconfigured roof volume within a Victorian terrace in Cambridge, creating a calm and spatially generous master suite through structural intervention and precise control of light and view.
The project works within the existing domestic envelope, reinterpreting the roof as inhabitable space rather than residual structure.
Context
The existing roof space was uninhabited and underutilised.
The brief focused on unlocking this volume without altering the external reading of the house within a conservation area, intensifying the use of the existing structure through minimal external change. The scheme accommodates a master bedroom with ensuite, incorporating bespoke storage and integrated desk furniture within the loft environment.
Architectural Strategy
A new roof structure redefines the existing volume, allowing the internal geometry to be opened up and reorganised into distinct spatial zones within the previously unused loft.
This intervention increases usable volume, improving head height, clarity of circulation, and overall spatial legibility.
A new stair is introduced from the first-floor landing, integrating the loft into the main domestic sequence rather than treating it as a separate level.
Light & Spatial Condition
Two carefully positioned conservation rooflights introduce controlled daylight to the bedroom and ensuite from the front roof plane.
At the rear, dormer insertions extend outlook and improve spatial perception, strengthening the relationship between interior volume and external context.
In the bedroom, bespoke joinery integrates desk and storage functions, allowing the window line to remain completely unobstructed. The absence of a balustrade at the opening creates a continuous framed view and a more direct relationship to sky and light.
Material & Detail
The intervention is deliberately restrained, with material choices derived from the tonal and textural qualities of the existing house.
A muted zinc roof extension sits in quiet contrast to the original slate roof, maintaining a coherent external reading within the conservation context.
Bespoke Accoya window frames define new openings with precision, clarifying the distinction between retained fabric and new insertion.
Performance
The reconfiguration improves both thermal and spatial efficiency by converting previously redundant roof volume into fully usable accommodation, reducing reliance on external extension and improving overall building performance.
Project Information

Location: Cambridge, UK
Status: Completed
Budget: £550,000
Scope: Structural roof reconfiguration and loft conversion
Key Features:
Roof restructured with steel ridge beam
New stair from first-floor landing
Creation of master suite within roof volume
Conservation rooflights to front elevation
Dormer insertions to rear elevation
Bespoke integrated desk and storage joinery
Uninterrupted window line through integrated furniture design
Work on site has recently been completed on this compact but beautiful loft extension in a central Conservation Area.
Using simple, natural materials the dormer is clad in zinc standing seam, with locally made hardwood windows.
