Home Extensions That Add Space & Value
A well-designed architectural extension is one of the single most reliable financial investments you can make in London property today. We engineer beautiful extensions designed to feel like they were part of the original home layout.
What Our Extension Service Includes
We handle all aspects of structural calculations, excavations, brickwork layers, roof alignments, glass lantern fittings, and decorators.
Rear Extensions
Extending the back of your building is the most straightforward, space-efficient way to unlock room. We manage structural piling, brick skins, membrane flat roofs, and seamless flooring joints.
Side Return Extensions
Narrow Victorian side gardens are prime targets. By infilling these strips, we can dramatic expand a dark layout into a wide, bright open-plan kitchen and diner.
Ground Floor Additions
For detached and semi-detached structures, a large wraparound ground-floor extension safely elevates your floor area and completely restructures family routines.
Open Plan Interiors
Most home additions require removing active structural partitions. We calculate lintel loads, position structural steel beams (RSJs), and coordinate surveyors.
Premium Glazing
We fit double or triple-glazed bifold panels, flush roof lanterns, and high-security anthracite structures to insulate details and capture maximum daylight.
Full Internal Fit-Out
Once weather-tight, our multi-trade veterans coordinate layout finishing details: electrical nodes, gas piping, screeding, plaster alignment, and pristine painting.
