Here’s a list of things to consider regarding adding an extra room in your house: Checking your deeds
First check the deeds to your house. It is crucial that you pay special attention to the deeds as they may contains information on the work you can and cannot do to the house.
Consult a solicitor for any extra help and advice in interpreting the deeds.
Note that if you’re allowed to build an extension, you’ll have to notify your mortgage lender if you are still paying a mortgage on your home.
the amount of space you’d like to add and how much space you can actually create from your existing house. When drawing a sketch to the extension, take into consideration the layout of your pipe runs and all electricity circuit layouts for an effective plumbing and wiring plan.
Size, setting and neighbours
You’ll need to determine the size of the new extension and its location. Extensions have to comply with Permitted Development or be approved with a Planning Application (or Lawful Development Certificate.) Most extensions also need Building Control Approval. Prior to starting the extension project, tell your neighbours about your plans. Get permission in writing from your neighbours about the project and make sure your neighbours are aware that extensions can take months to complete. If your neighbours have an extension, it’s worth finding out their experience with their project as rules and permissions vary from place to place.
As you need to add in an extra room at first floor level, planning and building a two-storey extension is complex. The extra space required for the first-floor room is taken from existing rooms and corridors so that your home’s structure isn’t compromised. For two-storey extensions, you also need to consider how the new extension will affect ventilation and natural lighting to the existing rooms. Simply adding a second storey on top of a single-storey extension is relatively easier to accomplish.
