Barn Conversion Architects

"Oh my word! This immense cruciform building seems to have kept much of its real self. The timber roof is the original. The old relay switches now operate lights, and yet it's architecture is all modern clarity and order”

"For every successful conversion, though, there's a transformation that doesn't hit the mark: a building stripped of the charm that made it appealing in the first place or designed with an impractical layout"

“To tackle an existing building like this, you have to take a forensic approach to create a piece of architecture within the existing structure. This is a prime example of someone knowing when to stop adding layers”

Frequently asked questions (FAQs) about barn conversions

Why should I hire a specialist barn building conversions?

Converting barns or other rural structures involves intricate planning, especially with heritage properties or those in conservation zones. A seasoned architect ensures your project meets regulations while preserving character and creating a functional, contemporary space. A specialist architect will manage the entire process from planning to construction, ensuring a sensitive, sustainable and successful outcome.

Do you work on listed barn conversions?

Yes. We regularly design schemes for protected and listed rural properties. Collaborating with conservation officers, we sensitively balance historical value with modern-day use and comfort.

Can you help with planning permission or Class Q conversions?

Absolutely. We handle all aspects of planning, including Class Q applications. We assess eligibility, prepare the necessary documentation, and liaise with local planning authorities on your behalf.

What are Class Q barn conversions?

Class Q permitted development allows certain agricultural structures to become residential properties without needing full planning approval. We help clients determine if their barn qualifies and guide them through the process. For further information see our blog post on Class Q conversions.

How do Class Q Prior Approval,  planning permission and Listed building consents differ?

Class Q, a form of permitted development General Permitted Development Order (GPDO). It allows certain types of agricultural buildings to be converted into residential use without the need for full planning permission. However, this route comes with strict eligibility criteria and limitations. In contrast, full Planning Approval offers greater flexibility and broader development potential. It is considered on a case-by-case basis, taking into account both national and local planning policies.

For Listed Buildings, a separate process applies. Listed Building Consent is required to make any alterations, whether internal or external. Carrying out work on a Listed Building without consent is a criminal offence and can lead to legal action. As specialist barn conversion architects we can advise on the best route for your project.

How much should I budget for architectural fees?

Fees vary depending on the complexity, location, condition of the barn and the level of service required. After an initial consultation, we provide a detailed fee proposal aligned with RIBA work stages and deliverables.

Where do you offer barn and rural property design services?

Our projects span the UK, particularly in regions such as Suffolk, Norfolk, Kent, Oxfordshire, and Buckinghamshire. We frequently work in conservation areas and Areas of Outstanding Natural Beauty (AONBs).
