Do I need planning permission?

You do not need a planning permission if you're just turning your cellar into a living room. You will need planning permission if you need to excavate the floor in order to have more headroom. You would need approval if your house is in a protected area. You will also need to comply with building regulations in case of creating an emergency escape route or achieving sufficient levels of insulation.

If you are unsure, seek advice from loft conversion specialists.

Common problems with basement conversions

  1. Ventilation - Many cellars smell dank and are badly ventilated. Carpets and soft furnishings can go mouldy if you do not tackle this issue. Windows can open whenever possible, but you can need to use a dehumidifier or a built-in mechanical ventilation system if the issue persists. To include the new basement spaces, you may want to expand your heating system, so you will need to ensure that your boiler is capable of dealing with extra radiators.
  2. Dark - Some cellars are damp because of a lack of ventilation and some are damp because water courses run below them. Various measures can be used to prevent moisture but it is invariably better to consult an expert. Get this right, because nobody wants to spend time in a damp basement. Check your flood risk too. If it’s high, it might be wise to take extra steps to avoid any potential for flooding.
  3. Damp - To avoid the gloomy space, a good design is a must. In case if you are using the space as a storage area or a utility room, less light would work. However, if you are planning a kitchen, bedroom, or a living room, you will have to find ways to bring in natural light. To increase the light, glazed ceiling panels, light wells, and skylights can be effective. You can also use the space for an indoor swimming pool or cinema room if your budget allows.
  1. Drainage - The construction of a bathroom or tub will require the drainage system or plumbing. There might also be a need of installing pumps or the drains might have to be redirected. 

Do we have to move out?

Moving out depends on the amount of work to be done. In case you don’t have any basement or you have solid floors, the work will be extensive.
