Our approach to conversions and change of use in Oxfordshire

A conversion often starts with a building that was never designed for its new use. We begin with a detailed site visit to understand the structure, services and condition, and work alongside your architect and consultants on planning and Building Regulations. At Horsefair on Chipping Norton’s high street, a former restaurant became a front commercial unit and a separate home at the rear, with floor levelling and new services throughout.

Our two in-house teams cover most of what a conversion needs, from groundworks, brickwork and structural alterations to roofing, plastering, flooring, NAPIT-accredited electrical work and Gas Safe registered heating. Coordinating these trades ourselves helps us sequence the strip-out, structural work, first fix and finishes in the right order. Where part of a building stays in use, or neighbours share a busy high street, we plan access, deliveries and working hours to keep disruption down.

Older commercial buildings often hide surprises, from uneven floors to dated wiring and tired structures, so we keep you informed as the work opens up. If something unexpected appears, we explain the options and any effect on scope and programme before going further. Compliance runs through every stage, including fire separation, sound insulation and ventilation for new homes, and at the end we walk through the finished property with you and remain on hand for aftercare.

testimonials

“North Oxford Developments completely transformed our home. What started as a tired, outdated property is now a beautiful, modern space that works perfectly for us as a family. The new extension and open-plan kitchen have made such a difference — it’s now the heart of our home. The quality of the finish throughout is excellent, and every detail was clearly thought through. The team were reliable, professional, and always kept us informed. They stuck to the timelines they set out and made the whole process far less stressful than we expected. We’re absolutely delighted with the end result and wouldn’t hesitate to recommend them.”

testimonials

“North Oxford Developments delivered an excellent result on this project. Building two new flats from the ground up alongside an existing property is no small task, but they managed it with confidence and professionalism throughout.

The finish on both units is to a very high standard, and their attention to detail really shows. They were well organised, communicated clearly, and kept the project running smoothly from start to finish.

We were particularly impressed with how they handled the logistics and coordination across the site. The end result speaks for itself, and we’d be more than happy to work with them again.”

Change of use in Oxfordshire: planning, prior approval and Building Regulations

The first question for any conversion is whether you need full planning permission or can use permitted development. Class MA allows many buildings in Class E (Commercial, Business and Service) to become homes through prior approval rather than a full application. The building must have been in qualifying use for at least two continuous years, and the earlier vacancy requirement and floorspace limit were removed in March 2024. Listed buildings, National Landscapes such as the Cotswolds and some other areas are excluded, and an Article 4 direction can remove the right locally.

Prior approval under Class MA is not a formality. The local planning authority considers transport, contamination, flooding, noise from nearby commercial premises, natural light in habitable rooms and, in conservation areas, the impact of ground-floor changes on the area’s character. New homes must also meet the nationally described space standard. Many conversions, including those in listed buildings, most mixed-use schemes and buildings outside Class E such as pubs, still need full planning permission, so speak to your architect and local planning authority before committing.

Whichever planning route applies, turning a commercial building into homes is a material change of use under the Building Regulations. The new dwellings must meet requirements for fire safety, sound insulation, ventilation, energy efficiency and more, so an application to a building control body is needed. As a commercial client you also have duties under CDM 2015, and in older non-domestic buildings an asbestos refurbishment and demolition survey should be carried out before strip-out begins. Local policies differ between Oxford, Cherwell and West Oxfordshire, so check early.

Frequently asked questions about conversions and change of use in Oxford

Not always. Class MA permitted development allows many Class E buildings, including shops and offices, to become homes through prior approval instead of full planning permission, provided the conditions are met. Listed buildings and some protected areas are excluded, and Article 4 directions can remove the right. Building Regulations approval is still required, so check with your local planning authority first.

Prior approval is a lighter application for development that is already permitted in principle. The council only assesses specific matters, which for Class MA include transport, contamination, flooding, noise, natural light and, in conservation areas, ground-floor impacts. If approval is given, the conversion must be completed within three years. It is not the same as full planning permission.

At least two years. The building must have been in qualifying commercial, business and service use for a continuous period of two years before the prior approval application. The earlier requirement for it to be vacant for three months was removed in March 2024. Your local planning authority may ask for evidence of that use, such as leases or trading records.

Yes. Our Horsefair project in Chipping Norton turned a former restaurant on the high street into a front commercial unit suitable for office or retail use, with a self-contained home at the rear. Mixed-use schemes need careful planning around separation, fire safety, sound insulation and access, and they often need full planning permission rather than prior approval.

Converting a commercial building into homes is a material change of use, so the new dwellings must meet requirements including fire safety, sound insulation, ventilation and energy efficiency. You will need approval from a building control body, with inspections as the work progresses. We coordinate the trades and work alongside your architect and building control so each stage is ready for inspection.
