Extensions in Oxfordshire

We are based in Witney, Oxfordshire and happy to consult on local residential extensions.

It is never too early to contact us if you’re planning an extension, as early engagement will ensure you have the right advice from the start.

We can complete a site visit to help you assess the feasibility of the project before you spend money on an architect or planning.  A large percentage of the costs of an extension are in the ground, so SWJ Consulting Ltd plays a vital role in ensuring you can have the extension you desire and that plans are correctly implemented.

How we work

We will work with you and your architect to ensure the design you want is structurally sound and achievable. There is nothing worse than falling in love with your architect’s vision only to find out you might have to compromise because of structural concerns.

  1. We will complete a site visit to check the accuracy of any existing plans you have and identify any issues
  2. We produce initial design ideas for feedback/questions from you and your architects
  3. We complete detailed drawings for your contractors, architect and warranty provider

We are local to Witney and will look at plans and complete site visits within a 30 mile radius for small extension projects. Give us a call today to discuss your project.
