Convert a cellar space into a utility space

Hello, You should start by contacting a specialist basement conversion company or a main builder who handles damp proofing, followed by a plumber for the fixtures. You will need tanking to stop water damage, and a saniflo pump if the toilet is below the main drain.

Good morning, I'm Andy from Asset Construction UK, we have completed many conversions, every cellar project is different and a lot needs to be taken into consideration, ie, celling heights, floor and wall construction type, invert levels of external sewer manholes, weather an internal sump and automated pump is required and the best type of tanking your cellar would require..... not to forget the costs involved to carry out these works to end up with a completely dry moisture free livable basement. We converted our cellar two years ago to create a wine cellar, utility room, hallway, double guest bedroom with an en-suite with French doors leading out to a sunken court yard for that early morning coffee. If you would like to get in touch please feel free to do so. Good luck with your project and which ever company / builder you use make sure they have the correct insurance for this work as it does not fall under the standard builders insurance policy and is very costly. Kind regards. Andy. Asset Construction UK.

Hi Charlie, Thanks for your question. The first person I'd recommend speaking to is a builder who has experience with cellar conversions, as they'll be able to assess the project as a whole rather than just one element of it. The key things that need looking at are whether the cellar is dry enough in its current condition, whether waterproofing (such as tanking or a cavity drain membrane system) is required, where the new drainage can connect into the existing foul drain, and whether there's sufficient headroom and ventilation. One other important consideration is the drainage. If the cellar floor is below the level of the existing foul drain (the invert level), waste from the proposed WC and washing machine may not be able to discharge by gravity alone. In that situation, a packaged lifting station or sump pump system is commonly installed to pump the waste up to the main drainage system. This is a well-established solution and can be incorporated into the overall design if required. From what you've described, creating a utility room with a washing machine, WC and basin is certainly achievable in many cellars, but the most appropriate solution will depend on the existing structure, drainage arrangement and condition of the space. I'd recommend arranging a site visit with an experienced contractor who can assess these elements, discuss the options with you and then provide a practical design together with a quotation. Good planning at the outset will always save time and money later on. I hope that helps, and I wish you every success with your project. Kind regards, Colin Cronin Prembuild Midlands Ltd

The best place to start is with an experienced builder who specialises in basement or cellar conversions. They can assess the space, check whether waterproofing (tanking or a cavity drainage system) is needed, and confirm whether it’s possible to install a toilet, sink and washing machine based on the existing drainage. If it’s feasible, the builder will usually organise the plumber, electrician and any other trades required, as well as advise on any Building Regulations requirements.
