Barn & Agricultural Conversions

New use for buildings that have run out of one

Traditional barns, agricultural buildings and farm diversification — including conversions to holiday letting.

Book a free consultation All services

Redundant agricultural buildings are among the most rewarding conversions and among the most technically demanding. The structure was never built to be lived in, so damp, insulation, floor build-ups and openings all have to be resolved without destroying what makes the building worth converting.

There are generally two planning routes: a full application, or permitted development for agricultural-to-residential change of use. The permitted development route has specific qualifying criteria and was amended in 2024, so the current position needs checking against your building rather than assumed.

Our Holiday Let Accommodation Conversion in North Norfolk converted existing agricultural silos — an unusually constrained structure — into letting accommodation.

How a conversion runs

1

Stage 1 — Preparation and Brief

Stage 1 is where we begin to understand your project. We are really interested in your project objectives and if you have a project budget. We often need to have a look at your property and assess the location and context before providing any advice. It’s important at this stage that we can clearly define your Project Brief, including spatial requirements.

2

Stage 2 — Concept Design

Stage 2 is where the design of your project really comes to life. Initially, we observe and record project opportunities and constraints onto a Site Analysis drawing. This can include details of; site access, restrictions from neighbouring properties, overlooking, noise, sun-paths, levels, views, security, local planning policies and historic maps etc. This research can make all the difference resulting in a design that makes the most of the site for your needs, and that is favourable in obtaining planning permission. We also record and update your project brief and any project strategies for approval.

3

Stage 3 — Spatial Coordination

Stage 3 is where the final concept design is formalised for planning approval or permitted development. The design evolves to include selected specifications and coordination with other consultants is carried out as required. A check review of Building Regulations at this stage ensures the design is compliant and ready to move forwards without significant changes. It’s important to develop and integrate the key features of a project at this stage, including strategies for sustainable design.

4

Stage 4 — Technical Design

Stage 4 is when all the technical design for your project is prepared. This includes detailed drawings and specifications for a contractor to price. As lead designer we often recommend any relevant additional Consultant Contacts required at this stage and often help with obtaining quotes for their involvement. If they have not already been appointed, this can include Structural Engineers, M&E Engineers, Interior Designers and Landscape Architects etc. but is dependent on the project. When all required consultants are confirmed, we arrange Design Team Meetings to discuss and develop the Technical Design.

5

Stage 5 — Manufacturing and Construction

Stage 5 is the manufacturing and construction stage of your project. Your preferred Contractor leads this stage to deliver your project on-site and your consultants provide support and guidance along the way.

6

Stage 6 — Handover

Stage 6 is the Handover for your project. At this stage we can help with the creation of a Building Manual, including the preparation of As-Built Drawings. We like to have a de-brief with the Project Team at this stage to discuss Project Performance and any learnings to take forward.

Danny is a joy to work with! Very creative and professional, and always available on the end of a phone. The plans he did for us were way beyond our expectations and flew through pre-planning with the notoriously tricky Broads Authority. The design is exceptional - well within the brief, yet far…

Barn & Agricultural Conversions — Frequently Asked Questions

Can I convert my barn under permitted development?

Possibly. The agricultural-to-residential route has qualifying criteria covering the building's prior use, its condition, floor area and the extent of works required. The rules were amended in 2024. We assess eligibility for your specific building rather than working from the previous position.

What if the barn is listed or in a conservation area?

That usually rules out the permitted development route and means a full application, plus listed building consent where relevant. It does not rule out the conversion — it changes how the design has to be argued.

Can the building take it structurally?

That is the first thing to establish. Some agricultural structures need substantial intervention, and the extent of that work can itself affect which planning route is available.

Can I convert to holiday letting rather than a dwelling?

Yes, and it is a common farm diversification route. The planning considerations differ from a residential conversion. Our North Norfolk silo conversion was designed for letting accommodation.
