Draw on expertise
It may be tempting to go without architectural input to save on your extension, but maximising budget is about achieving a great design as well as not overspending. The right designer will be able to help you save where you can and concentrate resources where they’re needed. Prospective designers should visit your property, so they’ll be able to assess potential difficulties that can add to costs, too. Check that they’ve worked on similar projects, and have a good record with local planners.
