Don't just add space. Transform how you live.

A well-designed extension should do more than give you extra room. It should make your home work better for the way you live.

From creating a better flow between rooms to maximising natural light and making the most of every space, thoughtful design can transform how your home looks, feels and functions.

Take a look at just a few of our extension designs, each created around our clients' homes, needs and aspirations.

Celebrating team milestones!

Congratulations to two members of the team who are celebrating their work anniversaries.

Luke Gittens, Co-Director, is celebrating an incredible 20 years with the business.

Aaron Morris, Architect, is celebrating 10 years with the team – technically 12 years since he joined, but with two of those years spent on a sabbatical travelling the world!

Two fantastic milestones and a brilliant reflection of the experience, commitment and contribution they both bring to the business.

Congratulations Luke and Aaron – here’s to many more years!

Every home is different, which is why we believe good architectural design starts with understanding how you want to live in your space.

From new homes and extensions to conversions, remodelling and carefully considered alterations, we create bespoke designs that combine practicality, character and contemporary living.

A concept exploring how an existing orangery could be better integrated with a listed property through a carefully considered extension.

The proposal creates a stronger connection between the existing house and orangery, introducing additional space while responding sensitively to the character of the historic building.

The design considers how scale, proportion, materials and natural light can work together to create a contemporary addition that sits comfortably alongside the existing architecture.

Just a concept at this stage, but an interesting example of how thoughtful design can help historic properties evolve to meet modern needs.

What happens when there’s no room to simply keep adding on?

You rethink the design.

For this previously extended cottage, the challenge was to create more from an existing structure while working within Green Belt constraints.

The solution involved some clever moves:

▪️ A new pitched roof created a generous master suite
▪️ The existing dormer was reimagined as a striking entrance gable
▪️ Internal floor space was carefully redistributed
▪️ The front door was relocated to improve the approach
▪️ A new staircase became a natural focal point within the home
▪️ Glazing and traditional materials were combined to complement the rural setting

The result is a home that feels completely reimagined — without simply relying on adding more floor space.

Thoughtful design can make all the difference.

From agricultural building to contemporary home.

Class Q developments can offer an opportunity to give redundant rural buildings a new purpose, while creating homes designed for modern living.

Our experience with Class Q projects means we understand the importance of balancing the requirements of planning with thoughtful architectural design making the most of the existing building while responding to its rural setting.

This contemporary barn conversion is a great example of how a sensitive approach to an existing structure can result in something distinctly modern.
