"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”

As experienced barn architects, David Nossiter Architects help clients transform agricultural buildings into distinctive homes, combining sensitive design with practical solutions for modern living.

With extensive experience in both traditional and steel-framed structures, David offers bespoke architectural solutions tailored to each project’s unique character and context.
Barn conversions involve complex planning, structural and heritage considerations that require specialist architectural expertise to successfully convert agricultural buildings into homes.
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 while creating liveable, high-performance homes.
A specialist barn conversion architect understands that every agricultural building has its own history, structure and opportunities. Whether working with a traditional timber-framed barn, a listed agricultural building or a modern steel-framed structure, the design approach must respond sensitively to the existing building and its surroundings

Converting barns or other rural structures involves intricate planning, requiring an architect experienced in existing buildings, heritage considerations and rural planning policy. A specialist barn conversion architect can help unlock the potential of your building while preserving its character and creating a functional, contemporary space. David 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.
