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.

The London Borough of Waltham Forest is a London borough in north east London, England. The local authority is Waltham Forest London Borough Council. It covers a total area of about 14.99 square miles. The borough is located in between Epping Forest and Essex towards the north, Redbridge to the east, Newham and Hackney to the south, and Haringey and Enfield to the west, where the River Lea and Lea Valley and the surrounding parkland forms a green corridor separating north and east London. Significant districts are Leyton and Leytonstone in the south, Walthamstow in the centre, and Chingford in the north.
In line with population estimates from the middle of 2014, Waltham Forest is a borough with a permanent population of about 268020 individuals. The north and south of the borough, split by the North Circular Road, contrast markedly in terms of ethnicity and socio-economic indicators, with built-up urban districts in the south having inner-city characteristics, and more affluent residential development in the north with open spaces, parks, and playing fields.
Historically referred to as the seat of the Arts and Crafts Movement under the stewardship of William Morris, Waltham Forest has continued to support numerous contemporary artists and art groups. These include the North East London Independent Artists group, based at the Changing Room Gallery in Lloyd Park, the 491 Gallery in Leytonstone, and a variety of independent artists, also primarily inside the Leytonstone area. Waltham Forest was among the list of six London boroughs that hosted the 2012 Summer Olympics.

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.
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.
Windows or lightwells can be a great way to introduce natural light into your basement, making it a more valuable, enjoyable space. However, they’re not always an essential requirement.
It’s important for your basement conversion to meet ventilation and fire safety building regulations. Windows can be a good way to do this, but they’re not the only option. Stack or mechanical ventilation, or ensuring that stairs up from your basement connect to an exit can be a good alternative.
So, while windows can be a great asset to your basement conversion, if you can’t afford them or they’re not structurally feasible, you can still create a basement conversion without them.
