Barn Conversion Architects in Derbyshire, Staffordshire & Leicestershire
Turning an agricultural building into a dream home takes more than a good eye for design, it takes knowing exactly what your local planning authority needs to say yes.
We’ve built that knowledge across Derbyshire, Staffordshire and Leicestershire, and we put it to work for every barn conversion and every family we work with.
Converting a Barn Without Full Planning Permission
Class Q permitted development rights allow eligible agricultural buildings to be converted into homes through a Prior Approval application, a significantly simpler and faster route than full planning.
Following updates in May 2025, the current rules allow conversion of up to 10 dwellings per agricultural unit, a maximum of 150m² per dwelling, and a rear extension of up to 4m onto existing hardstanding.
- Maximum per dwelling 150m² floor space
- Dwellings per unit: Up to 10 homes
- Rear extension allowed: Up to 4m on hardstanding
- Agricultural use before 24 July 2023
When Planning Gives You More
When a barn doesn’t qualify for Class Q, or when you want a more ambitious design than Class Q permits, a full planning application is required. Our team coordinates all specialist reports and manages the process end-to-end.
What Planning Officers Look For:
- Agricultural character and massing preserved
- Materials sympathetic to the rural setting
- No suburban detailing in extensions or landscaping
- Ecology requirements addressed (bats, barn owls)
- Structural evidence the building can be converted

Some of Our Completed Barn Conversions:
What years of planning beautiful and successful barn conversions have taught us:
Get the structural survey right, early:
For Class Q applications, a structural survey is a core part of the prior approval submission. But beyond the planning requirement, it tells you what you’re really working with. We commission it as early as possible — it shapes everything that follows.
The Planning Route Matters
Class Q is faster but constrained. Full planning takes longer but gives you significantly more freedom, a bigger home, a more ambitious design. We always sit down with clients early to work through which route genuinely serves their vision better.
Character is your greatest asset
Original brickwork, timber frames, high eaves, these are what planning officers want preserved, and what future occupants love most. At Grasscroft Barn, Dalbury Lees, the original brick character became the centrepiece of the whole design.
Well-timed Ecology
Most people are surprised to learn that a single bat roost can delay a planning application by months. Agricultural buildings are prime habitat for bats and barn owls – both legally protected and survey windows are fixed by the seasons, not your timeline. We’ve seen well-planned projects grind to a halt because ecology wasn’t factored in early enough. We make sure it always is.
Light is designed in - not added later
