Renovations and Extensions

Creativity isn’t confined to ambitious new-build projects. At Milton, we enjoy finding creative solutions to upgrading and extending existing homes, whether we’re adapting heritage buildings to accommodate contemporary family living or revamping modernist spaces to give them a new lease of life. The addition of new and carefully considered elements can transform the way people inhabit and enjoy their homes for good.

The White House

An elegant Arts & Crafts house in the Marlborough conservation area with a contemporary extension offering direct access to the terrace and garden beyond.


This semi-detached Oxford townhouse was built in 1877. Since then it has had a number of additions and alterations, although none that have really made a positive contribution to its history. Our proposals for full refurbishment and ground floor extension have added a real sense of modern style to the house, and introduced a strong connection to the garden.

Barton House

Our client wanted to transform this 1980’s house with some strikingly modern interventions. Easier said than done considering its location in the heart of the village conservation area, but we made our case and convinced the Planners to agree. The result is a beautiful home that seamlessly integrates the interior spaces with the wonderful garden.

Wiltshire House

This house was built to a very idiosyncratic brief in the 1980’s so when our clients acquired it, they decided it all had to change. Vestiges of the original house are evident but there’s more that’s new than old. The house sits in a wonderful landscape and we chose the walled garden as the ideal place for a new indoor pool. Designed as a secret, hidden behind the old garden wall, this is where the family come to have fun and enjoy the sheltered privacy of the enclosed outdoor spaces.

Waterside Lodge

An impressive upgrade to a modern home that extends both inside and outside living space and creates a fresh and dramatic perspective in this desirable riverside location.

Waverley House

This 1890’s terraced cottage has been brought fully up to date with a stylish ground floor extension. It was a big challenge to achieve such a wonderful sense of space with an unashamedly contemporary feel without taking away from the character of the original building, but we feel we’ve managed to achieve just that.

George Lane

A stylish and contemporary home that celebrates its mid-century origins while affording comfortable and versatile accommodation fit for a modern family.

Old School House

Our clients were keen to explore innovative timber building techniques and commissioned Slovenian company Riko to manufacture the whole extension at their factory the other side of the Alps. “On Monday there was just a concrete slab in the ground. Now it’s Friday and the whole extension is almost built.” (Tim, client)


This house commands a beautiful position overlooking the town. Our clients wanted to carry out major extensions and alterations to create their dream family home. We carefully stripped away previous additions and added new to achieve a property that looks as if it’s always been that way.

The Green

We always relish the challenge of working with a listed building, transforming it into a modern place to live without destroying the character of the original. This single-storey extension runs across the rear of the house, replacing a number of very tired lean-to’s to create a new sitting room and study, as well as bringing new life to the kitchen and opening the house to the garden.

Lanchester Road

This 1930’s suburban London house has been brought fully up to date with a dramatic ground floor extension and master-bedroom suite on the top floor. It was a big challenge to achieve an open-plan ground floor whilst maintaining the necessary fire separation for the stair, but we found the solution with a super-sized glass sliding door.

Broome Manor House

Knocking a four-metre wide hole through a one-metre thick stone wall was a nerve-wracking experience. But this new kitchen addition made it all worthwhile. Offering a totally modern space in which to cook, eat and relax, now with all-round views of the garden, this single room has transformed the house and our clients’ enjoyment of it.

George Lane 2

We’ve become experts at turning rather tired 1960’s houses into contemporary family homes. This house needed some ‘TLC’ after three decades of ill-considered alterations and now sets a benchmark for the rest of the street.
