House Extension

We at Southwest Builders can help you to make your dream House Extension.

Building an extension is a great way to create extra space. Whether it's to accommodate your growing family, or simply to help you spread out a little.

Extending the house is an economical way to provide for the extra space needed whilst maintaining all of the comforts of your existing environment and lifestyle. In addition to this, the investment in your current property will most definitely be reflected in its property value.

Important Factors to Consider

  • Will you require planning permission or building regulations?
  • Will you require structural calculations?
  • You are allowed to build under permitted development approximately 70 meters cubed, subject to no previous construction work.
  • Cost: £1300 - £1600 per square meter for a single-story extension. We offer no-obligation quotes.
  • Will the central heating boiler be capable of further expansion?
  • Will the builder install our kitchen or bath-suite?
