It’s true that many people who desire a home conversion for their property are put off by the whole process, due to the fact that they are unaware of what the first stage is. Maybe you are unsure whether or not you need planning permission or an architect? Or perhaps, you’re in the dark about how much a proposed project may cost and how long it will take? Kent Extensions take the confusion out of building a House conversion, by answering all these questions on your behalf. As we work closely with companies who can apply for planning permission and involve architects with the project, complete building applications and assist in delivering full project proposals and costs in writing, we therefore help you with all those questions you naturally have before you want to proceed.

Many people put off extensions because they do not know what the first stage is. Frequently asked questions tend to be:

  • Do I need planning permission? (See below for more information) 
  • Do I need an architect?
  • How long will the project take?
  • How much will it cost me?

We work closely with companies that can apply for planning permission on your behalf, get architects involved, complete building application work, provide you with a full cost and project plan in writing and help you with all your questions that naturally you will want to know before you proceed.
