Basement construction and conversion in North and West London

A basement or cellar conversion or construction can add a great deal of usable storage or living space to any property, not to mention value.

New builds - adding a basement or cellar at the outset is a cost-effective way of maximising your property's potential.

Conversion - this is becoming increasingly popular; unsurprisingly, given that it's a more affordable way of adding space to your home than relocating.

Basement ideas

Straightforward storage space is always an option, but the potential for basements is almost limitless. A bedroom or two is an obvious choice, with or without a bathroom, but others prefer an office. Many people choose to focus on entertainment space - playroom, games room, gym or spa, or all-round entertainment space for music, films and so on.

If the money and the space are available, then the possibilities are almost limitless. We can help you make the right choices to meet your needs, budget and space.

Your basement need not be confined to a single level below your property either. Two level basements are possible, and you can also extend below your garden or driveway.

Surveying, planning and designing your basement

The first step is to ensure that your basement is suitable for conversion. Some areas of London are vulnerable to subsidence or have a high water table. The structure and fabric of your building is also an important consideration.

Unless your alterations are very minor, you will also need planning permission, and it's vital to identify and draw up detailed plans for what's required, and also to know what is likely to get passed and what isn't. We can assist with ideas as well as all areas of regulation, supplying or working closely with your chosen professionals, including architects, party wall surveyors and structural engineers, as well as local planners, seeing through your basement projects from conception through to completion.

Basement construction

The construction itself covers all aspects, including site preparation, demolition and disposal of excavated material. All necessary areas of construction and suitable materials are covered, including underpinning or more modern techniques such as reinforced concrete walls. At all times the project is carefully project managed.

We also take care to ensure thorough waterproofing - an important consideration in many areas of North and West London, where subsidence and high water tables can be an issue.
