Is my property suitable for an extension?

There are a number of factors that affect your house's suitability for an extension, including:

  • Area - if your house is in a conservation area or a district with planning restrictions, you may have more limited extension options.
  • Neighbours - your direct neighbours will have a say in whether your plans negatively affect their quality of life.
  • Budget - your plans should ideally give a decent return on your investment with regards to property value and living space.
  • Timetable - having a set deadline on your build can affect the type of extension you can manage.

At J Build we have years of experience planning and implementing home extension designs. Your satisfaction is our number one priority so we will ensure the final build matches your desires as closely as possible.
