Basement conversions fluctuate in cost depending on project scale, professionals hired and location. If your basement conversion doesnât need any construction work, then it should cost relatively little. However, the majority of projects at least need damp proofing and water proofing work, if not insulation, heating, electrical work and more. This means that even smaller basement conversion projects are still relatively expensive. The average UK cost ranges from £30,000 - £50,000.

If your basement has a cavity drain membrane, it’ll need a pump to move water away from the exterior of your basement and prevent flooding.
Sump pumps can be noisy, but they don’t have to be. Generally, if you have a well-designed pump that’s installed correctly, you shouldn’t find it a problem. For best results, hire a skilled, experienced professional to supply and install your drainage system.
The best way to go about converting a basement depends on its current condition and what you’d like to use it for.
If you’re happy with its size and structure, and just want to turn it into useful storage space, then your project shouldn’t be too complicated. You’ll simply need to make sure it’s damp proof and waterproof – either by fitting tanking or a cavity drain membrane with a sump and pump. You may also need to invest in new flooring, fit basic lighting, and plaster and paint the walls and ceiling.
If you’d like to turn your basement into living space, then you’ll need to think about ventilation, insulation and heating. If this involves creating a kitchen or bathroom, you’ll also need to incorporate plumbing.
If you want to extend your basement, add lightwells, or fit windows and a sunken garden, this makes things much more complicated. You’ll probably want to hire an architect or basement conversion building specialist to help you with the design and planning, and you’ll need a structural engineer to help you ensure your property is sufficiently supported.
In some cases, it’s possible to convert a basement into an apartment. This can be a great way to incorporate an additional dwelling into your property and increase its value. However, converting a basement into an apartment can be quite expensive and time-consuming.
As with any type of dwelling, you’ll need to think about basic things like access, damp proofing, ventilation, insulation, heating, electrics, plumbing, lighting and décor. If you’re planning on extending your basement, then you’ll also need to ensure that your property is sufficiently supported.
It’s a good idea to consult a professional, like a basement conversion building specialist, to find out how feasible your project is before you go ahead with it.
Whether a basement is worth converting depends on your location and how much work it requires.
A basement conversion can be a great way to add space to your home, and can raise your property value. However, it can also be one of the most expensive ways to do this, so if there’s a possibility to extend your property, or convert a loft or garage, it’s worth considering this first.
You should also compare how much your basement conversion will cost with the amount it could raise your property value by. In some areas, a quality basement conversion could earn you money in the long run, but in others it’ll only cost you. If you’re planning on staying in your property for a long time this might not matter to you, but if it’s not your forever home then it’s an important thing to think about.
