Where the view
earns its place.

From Sandbanks to the Isle of Purbeck, the Dorset and Hampshire coastline is some of the most coveted land in England. We build homes designed around the horizon — contemporary architecture in glass, stone and timber, built to last generations.

Land · Barn · Estate

Where history
meets what's next.

The New Forest, Wiltshire valleys, Dorset downland — land with character and planning complexity. From Class Q agricultural conversions to new manor-scale homes, we work with the land rather than against it.

Selected work

No two alike.

Each project began with an exceptional piece of land and an absolute refusal to build anything ordinary. The work spans converted barns, new country houses and multigenerational homes — unified only by the standard they were held to.

The brief behind The Barn

"A family needed two homes in one — a luxury principal residence and a purpose-built accessible home for their disabled son, Luke, who requires 24-hour care."

Understanding that brief — and delivering both homes on the same site, from the same Class Q application — required a builder willing to go far beyond the standard specification. This is the kind of project Whitebarn exists for.

Michael James
"I've never been interested in building what's easy. Only in building what's right."
Michael James

Built on instinct.
Proven by time.

In 2012, the government introduced Class Q permitted development rights — legislation that allowed agricultural buildings to be converted into homes. Most in the industry overlooked it.

Michael James did not. He spent the following years becoming the country's leading authority on Class Q planning — studying the legislation at a level no one else had bothered to reach. In Winchester, on a large barn called Durley Hall Farm, he secured what is believed to be the first Class Q planning permission ever granted in the country. It was achieved through a provision rarely invoked: Winchester City Council had failed to determine the application within the statutory 56-day window.

That instinct — to move before the market, to understand what others hadn't yet read — is the same instinct behind every project since.

Today, Michael builds across Dorset, Hampshire, Wiltshire and internationally — working alongside the best architects in the region, including Arc Architects, who designed Holtwood House. He is a master home builder. He has sourced passive doors in Poland, cladding and finishes in Indonesia, tiles in Spain, kitchens in Germany, and a specific cooker for a client's kitchen from France. He is currently completing a private residence in Lombok, Indonesia — commissioned by a Dorset client who trusted him enough to take the work to the other side of the world.

He works with a small number of clients each year. He is present on site. He picks up the phone.

How it works

Your plot.
Your vision.
No compromise.

Whitebarn exists for one type of client: someone with an exceptional plot — or the ambition to find one — who wants a home built entirely around their life, not a developer's assumptions about it.

Site & Planning
Finding the opportunity others miss

Michael's background in Class Q and complex residential planning means he sees potential where others don't. Whether you have a site already or need help identifying one — coastline, farmland, estate acreage — he can advise on what's achievable before you commit a penny.

Design & Build
One point of contact. No gaps in the chain.

From first architectural sketch to the moment you walk through the door, Michael oversees everything personally. He works alongside your chosen architect — or can recommend exceptional practices — and manages every craftsperson, supplier and subcontractor directly. The specification is uncompromising. The budget is real and respected.

The Bespoke Layer
Going as far as the brief demands

If the right kitchen comes from Germany, we go to Germany. If the stone needs sourcing from a specific quarry, we source it. If the client wants to see the material before committing, we make it happen. This level of involvement isn't a premium add-on. It's simply how we work.

Where we work

The South of England
is home. The brief
decides the rest.

The Dorset & Hampshire Coast
Sandbanks · Canford Cliffs · Purbeck

Some of the most valuable residential land in England. Contemporary homes in glass, stone and timber — designed around the view, built to justify the setting. We are based near Sandbanks and know this coastline intimately.

The Country Interior
New Forest · Wiltshire · Dorset Downland

Land with history, scale and planning complexity. Barn conversions, manor-scale new builds, country estates. This is where the Class Q expertise lives — and where Horseshoes Farm proved what's possible with the right approach to planning.

International
Lombok · Bali · Europe

A current project is under construction in Lombok, Indonesia. Previous commissions have required sourcing in Poland, Germany, France, Spain and Bali. If the brief is right, we will go where it leads. Project values from £2M — no upper limit.

For architects & agents

The builder your
best clients have
been looking for.

Michael James works alongside architects, estate agents and planning consultants — not in competition with them. If you have a client with an exceptional brief and need a builder who will honour the design intent without cutting corners or cutting you out, this is that conversation.

He has an established relationship with Arc Architects — the leading residential practice in Dorset and Hampshire — and is actively seeking new introductions with architects and agents working at the premium end of the market across Sandbanks, the New Forest and Wiltshire.

"We'd built a house before. We thought we knew what the process felt like. This was completely different. Michael was present — genuinely present — and every change we wanted to make felt welcomed, not tolerated."
