Creating Your Dream Space Underground: What You Need To Know

An unused basement or cellar holds exciting potential as an extension to your home. However, before you convert it into a home gym, an office, or whatever your dream space may be, there are several important considerations to keep in mind. In this article, we’ll answer some common questions about basement conversions to ensure you’re well-prepared for your renovation project.

Do I Need Planning Permission? 

Yes, you will need planning permission when converting a basement or cellar. Typically, a simple conversion from a storage room to a habitable area only requires building control approval. However, if you plan to make structural changes like adding windows, doors, or external access, you may need to obtain additional planning consent. Whether you need any extra planning permissions depends on the scope of your specific project. One of our surveyors can advise you on how to obtain this permission to comply with local regulations.

Will Damp or Mould Be an Issue? 

Before starting your project, we will need to address any potential damp or mould issues. Basements are prone to dampness because they are below ground level. Your basement or cellar may be suffering from a moisture issue if you notice any of the following signs:

  • Discoloured or wet patches 
  • Salt residue or damage to wall plaster
  • Musty odour
  • Mould
  • Tide marks on walls 
  • Decaying or warped skirting boards
  • Peeling paint

Will I Need Professional Assistance?

Converting a basement can become a complex and lengthy task, requiring professional assistance. While some DIY can be tempting, there’s nothing worse than a project half-done or one that needs extra attention later. 

Our basement conversion specialists at ABS Basement Systems will work alongside you to give your basement the treatment it needs. We install expert dry basement solutions from basement tanking and repairs to humidity-controlled ventilation, thermal insulation, and mechanical and electric services, adhering to the basement waterproofing guidelines set by the British Standards Institute.

How Long Does a Basement Conversion Take?

A basement conversion can be completed in just a few weeks unless there are severe moisture issues. Installing a sump pump and other basement waterproofing systems may delay the project by a month or two. Whatever your project requirements, our basement conversion specialists at ABS Basement Systems can assess your basement, provide a quote, and give you an estimate of how long the job will take.
