Southampton Architecture

Houses for a city between the water and the downs.

Southampton is a city of tight plots, mature street trees and long views out to the Test valley and the edge of the Forest, and we design for exactly that kind of site.

Our story.

Who are we?

Most of the sites we see in Southampton are constrained in some way: a narrow side garden, a Victorian terrace with neighbours close on both sides, a corner plot with trees protected on it, or land low enough to need a flood risk assessment.

Those constraints are the design brief. A rear extension that brings light into a deep plan, a replacement dwelling that fits the scale of its street, or a new house on a backland plot that gives the neighbours the privacy they are entitled to — all need the same measured approach to overlooking, daylight, drainage and parking.

With more than 450 projects behind us, we design new homes, extensions, luxury developments and complex renovations across Hampshire and the wider South of England, always in close collaboration with you.

What we do.

From appraisal to completion.

We begin with a proper appraisal of the site — access, levels, trees, drainage, services and planning history — so you know early what the land can carry.

We handle the planning process, including conservation area and listed building consent where it applies, and prepare the drawings, statements and specialist input a sensitive site needs.

From there we take the design through building regulations and technical detailing, and stay close to the build so the finished house matches the drawings.

Our experience in Southampton.

One studio.

From our Hampshire studio we are on site in Southampton within half an hour, working with local surveyors, structural engineers and contractors who know the city’s ground conditions and its planners.

10+ years.

Over a decade of residential work in and around the city, from modest rear extensions to substantial new houses, with planning and technical design handled by the same team throughout.

450+ projects.

More than 450 projects across Hampshire and the South of England, including tight urban plots where overlooking, daylight and drainage decide the scheme as much as the design does.
