Country Life has once again delved into its little black book and fully updated this list of the finest architects in Britain – an indispensable guide if you're considering serious work on your home.

The appetite for constructing a country house from scratch has never been greater. As family life in the 21st century turns ever more around large, open-plan spaces and the question of privacy and seclusion becomes more paramount, the solution is often to buy a greenfield site and build the dream.

It’s a process that demands careful thought. What makes a great English country house is the marriage between the building and the landscape. It’s this element, as well as a good, working relationship between the architect and the local planning officer, that can be the making or breaking of a new-build scheme.

Fortunately for anyone embarking on such a project — be it large-scale or modest in size — the pool of architectural talent in this country continues to grow. The output of our top-rated country-house architects varies in scale and style from classically inspired country mansions to distinctive new houses in a modern idiom, as well as traditional and contemporary barn conversions, family houses and domestic extensions to listed or sensitive buildings.

ADAM Architecture
