Loft Conversions in Oxford, Aylesbury, Bicester & the Surrounding Areas

When it comes to loft conversions, our clients gain so much more than valuable new living space. Conversion projects also make a fantastic long-term investment, often increasing the market value of a home by tens of thousands of pounds. Naturally, certain conditions like location and the type of room installed effect the final valuation. DJT Builders (Oxfordshire) Ltd happily provides valuable advice and guidance from the outset, ensuring your final conversion provides the best possible return on your investment in every respect.

Based in Kidlington, our building company undertakes loft conversions throughout Oxfordshire and the neighbouring areas. We have direct access to all our primary service locations, including Aylesbury, Banbury, Bicester, Brackley, Buckingham, Oxford and Witney.


Whether you have design aspirations for a master bedroom, a children’s playroom, a home office, a man cave or simply some extra space to relax in, our building company offers a complete design-and-build service to optimise the most underused space in practically every home. Our builders and tradespeople have equal proficiency with every type of loft conversion, so we have the ability to meet every requirement.


Planning Permission


Due to their classification as permitted development, loft conversions rarely require planning permission. In short, this means that, subject to compliance with certain conditions granted by parliament, the conversion of any loft space outside of a designated area has very few planning restrictions.


These conditions include:


  • The build has no raised balcony and no raised platform
  • Loft conversions do not extend beyond the roof slope plane
  • The roof does not exceed an extra 40m³ on a terraced property
  • The materials used match those of the property’s current décor
  • The conversion doesn’t exceed the highest part of the roofing structure
  • The roof does not exceed an extra 50m³ on detached or semi-detached properties
  • Side-facing windows must have obscured glass and a 1.7m opening above the floor


Most homes in Aylesbury, Bicester, Oxford and the wider Oxfordshire region have no issues with permitted development rights as long as they don’t sit within a conservation area, national park, heritage site or a location classified as an area of natural beauty. Listed properties also have special requirements.


Please note, planning permission and compliancy with the latest Building Regulations represent two very different things. Even when completed under permitted development rights, loft conversions must fully comply with all relevant regulations pertaining to structural, fire and electrical safety.


DJT Builders (Oxfordshire) Ltd advises on your obligations during an initial consultation.


Loft Conversion Styles


Most of our clients have four different loft conversions to choose from, although the architectural style of the existing home usually has a significant say in the final decision. Each conversion varies in cost and complexity. Our building company typically completes each project within four to six weeks. More complex projects run slightly longer, sometimes extending to ten weeks.


The four standard types of loft conversion include:


  • Conversion with Roof Lights
  • Dormer Conversion
  • Mansard Conversion
  • Hip-to-Gable Conversion


We work in close conjunction with homeowners in Aylesbury, Bicester, Oxford and the neighbouring areas when conducting site surveys. During this process, we discuss every aspect of your conversion, taking into account your ideas, concepts and aspirations for the finished space.


As a proud member of the NHBC, DJT Builders (Oxfordshire) Ltd provides insurance-backed warranties. With our industry experience of more than 30 years, we remain the trusted building company of choice for loft conversions in the Oxfordshire region.
