"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”
David Nossiter Architects are specialist barn conversion architects working across the UK, providing architectural design, planning and delivery services for high-quality barn conversions
David Nossiter’s expert advice on barn conversions has appeared in Homebuilding & Renovating magazine, covering design, layout, and common mistakes in barn conversions
With extensive experience in both traditional and steel-framed structures, David offers bespoke architectural solutions tailored to each project’s unique character and context.
Many older agricultural buildings have become unsuitable for viable farming use. The highest quality historic barns are protected by Listing. However, there are many other barns, both traditional and modern that have fallen into disuse and sit idle. Reusing and converting these buildings is a sustainable way of building. A specialist in rural building conversions understands the complexities and unique challenges of these projects.
We understand:
How to navigate planning permission and listed building consent
The structural and thermal complexities of adapting historic rural buildings
How to work closely with conservation officers, structural engineers, and ecological consultants
The importance of sustainability and retaining local vernacular character
David is familiar with traditional and Listed barns as well as contemporary steel and concrete framed structures.
Solutions are proposed that are individual to each project, whether it be an existing conversion requiring eco-fitting and modernising, such as Pye Barn in Oxfordshire, or a concrete and steel framed barn requiring conversion, such as Spring Water Barn in Kent.
Whether working with heritage assets or modern barns, we bring award-winning design to every rural transformation.

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.
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.
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.
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.
Class Q, part of the General Permitted Development Order (GPDO) allows certain types of agricultural buildings to be converted into residential use without full planning permission, subject to a Prior Approval process. However, this route comes with strict eligibility criteria and limitations, particularly around the condition of the existing structure, the extent of the works and the location of the building. In contrast, full planning permission offers greater flexibility and broader development potential. Applications are considered on a case-by-case basis, taking into account both national and local planning policies and are often more suitable for complex barn conversions.
For Listed Buildings, a separate process applies. Listed Building Consent is required for any alterations, whether internal or external. Carrying out work without consent is a criminal offence and can lead to legal action. As specialist barn conversion architects we advise on the more appropriate route and develop an individual strategy for your building and site.
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.
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).
Architects assess eligibility, prepare applications, and liaise with local councils, especially vital for listed barns, structures in Areas of Outstanding Natural Beauty, or projects under Class Q permitted development. This ensures your project complies with all regulations and reduces costly revisions.
Our award-winning project, Church Hill Barn, has received national recognition for its heritage-sensitive barn conversion design. It won the Sunday Times British Homes Awards, was a finalist at the Architects’ Journal Retrofit Awards, and was featured on Grand Designs.
These accolades reflect our expertise in barn conversion architecture, planning strategy, and working with historic rural buildings.
