Barn Conversion Services

Class Q Specialists

We convert agricultural buildings into modern homes under Class Q permitted development rights. Our team delivers fully compliant barn conversions that retain rural character while meeting all current building standards.

Barn Conversion Class Q

Full Project Delivery

We manage:

  • Class Q application and approval
  • Architectural and structural design
  • Foundations, insulation, and drainage
  • Internal layout, plumbing, and electrics
  • Final decoration and handover

What is Class Q?

Class Q allows the conversion of agricultural buildings into residential dwellings without full planning permission. It covers:

  • Up to 5 homes per site
  • Internal works and new windows/doors
  • Reasonable structural reinforcements

We guide you through the process, from eligibility checks to completed build.

Full Design & Planning Support

We carry out detailed site assessments and submit all required drawings, statements, and structural reports to the local authority. If Class Q is not possible, we can submit a full planning application as an alternative route.

FAQ's About Barn Conversions

“Class Q” refers to permitted development rights in England allowing the conversion of certain agricultural buildings into residential dwellings without the need for a full planning application. Your building must meet eligibility criteria including its prior agricultural use, size, structural strength (or ability to be reinforced), external footprint, and location. We at Axminster Design & Build will undertake an initial assessment of your site, confirm whether the building is likely to qualify, and advise on the application process.

If Class Q is not possible (for instance due to building condition, previous use, or location), then a full planning application for a barn conversion may be required. We can guide you through the full design & planning route including submitting drawings, structural reports and coordinating with your local authority.

Yes we offer a full “design & build” service. That includes the initial site assessment, architectural and structural design, foundations, insulation, drainage, internal layout, plumbing, electrics, finishes, decoration and handover.

We aim to retain the character of the original agricultural building (e.g., exposed beams, vaulted ceilings, large openings), while incorporating modern building standards and energy efficiency. Typical features include open‐plan living, high‐spec finishes and modern services.

Because older agricultural buildings typically weren’t constructed to modern thermal standards, we ensure up to date insulation, glazing, heating systems and drainage are included. We tailor each scheme to meet current building regulations and ensure your home is comfortable, efficient and long‐lasting.

Yes, we provide a full turnkey solution including design, planning, construction, and final handover.

The timescale depends on many factors: the size and condition of the existing building, whether Class Q applies, the complexity of the work, access, finishes, and local authority approvals. On average, once build work begins, a conversion might take several months (e.g., 6-12 months) but you should allow for the planning/design stage too.

Some of the potential additional costs include structural strengthening (if the barn isn’t in good shape), upgrading services (water, drainage, electricity), foundation works, insulation improvements, dealing with access, site logistics and any heritage or planning constraints. We recommend allowing a contingency budget and ensuring full transparency in the quotation process.

Our aim is to sensitively convert the agricultural building so that its rural character is retained while delivering modern functionality. This typically means preserving original elements like timber beams, stone or timber cladding, pitched roofs, large openings, and integrating large windows/bi-fold doors in a way that complements rather than detracts from the barn’s original vernacular.
