More house.
Without moving house.
A premium architectural extension, engineered to meet your existing home properly — in daylight, in level and in character.
An AAVA Extension is a separate product category, not a larger garden room. It is designed as part of your house: the connection to the existing structure, the roof line, the floor level and the way light travels between old and new are the whole job.
The rooms that change how a house feels.
Most extensions are asked to do two things at once: add floor area, and fix something about the plan that never worked. We design for both.
Kitchen & dining
The room the house ends up living in. Daylight from two aspects wherever the site allows.
Family living
Space that absorbs a whole household without feeling like a corridor.
Entertaining
A generous opening to the garden, and lighting that carries into the evening.
Home office
A room with a door, properly serviced and acoustically considered.
Additional bedroom space
Ground-floor accommodation where stairs are becoming the problem.
Larger open-plan living
One connected space, zoned by light, level and ceiling rather than by walls.
The join is the design.
Architectural integration
Proportion, roof line, floor level and material are resolved against the existing house rather than imposed on it.
Large glazed openings
Generous, thermally broken glazing sized and oriented for the site, with solar gain and privacy considered together.
Premium insulation
A continuous, high-performance envelope — including where the new fabric meets the old.
Smart heating
Zoned heating that works with the existing system rather than against it.
Lighting
Layered lighting designed for a room that is used from breakfast to late evening.
Ventilation
Ventilation specified for a space with cooking, glazing and a lot of occupancy.
The connection
A carefully engineered structural and thermal connection to the existing house — the part that is easiest to get wrong.
Up to 45 m².
Up to 45 m², subject to the existing house, previous extensions and site conditions.
The regulatory framework identifies Planning Class 1 for extensions, with a maximum of 45 m² subject to cumulative and site-specific conditions. Cumulative matters: any previous extension to the house counts towards the total.
That figure is a ceiling, not an entitlement. What your house can take — structurally, architecturally and in planning terms — is established during site qualification.
