• Essential Home Extension Planning Checklist

  Expanding your home is a significant investment. Before the first brick is laid, we recommend homeowners in North Somerset consider the following essential steps:

  • Define Your Purpose: Are you looking for a quiet home office, a larger kitchen-diner for entertaining, or an extra bedroom? Defining the primary use helps our builders optimize the layout.

  • Budget for the “Hidden” Costs: Beyond the build, remember to account for VAT, architect fees, structural engineer reports, and internal finishes like flooring and lighting.

  • Check Your Boundaries: Identify the exact location of your property lines and any shared “party walls” with neighbors. Early communication with neighbors is crucial for a smooth project.

  • Review Local Planning Constraints: While many extensions fall under Permitted Development, others require formal Planning Permission from North Somerset Council. We can help you determine which applies to your project.

  • Utility Access: Locate your existing drainage, gas, and electricity meters. Moving these can impact the overall cost and design of the extension.

  • Structural Integrity: Consider how the new extension will tie into the existing house. This often involves the installation of steel beams (RSJs) to create open-plan spaces safely.

You can refer to our Testimonials page to see our reviews from previous clients who we have carried out extensions for. When carrying out work we are very conscientious about the cleanliness of the site and during an extension it can get dusty and untidy, but we make sure at the end of everyday to have a clean and tidy site and our equipment stored safely.
