Is My Property Suitable For A Basement Conversion Mayfair ?

Before undertaking a basement conversion project, it is a must to ensure that it is a realistic investment for your property. A basement can be the ideal option if you are searching for space for a playroom, a home theatre, a bespoke gym, or, on a more practical note, to move the utility room to create more space above ground.

Whether converting your basement from a cellar or storage room to a more habitable space or excavating the ground beneath your home to create a whole new space, consider the following to determine whether your property is suitable for a basement conversion.

  • Building access -
    Does your property have ample on-site access for builders during the renovation process to remove soil and waste, supply equipment, and store materials while causing you minimal disruption? You will need to find temporary accommodation if you do not have enough rooms.

  • Neighbours -
    Do not forget you have neighbours! When carrying out a basement conversion, see the impact it would have on them. Inform them about the work you are undertaking and seek a party wall agreement. This will ensure that their property is not disrupted by your work.

  • Structure -
    What is your property's structural condition and the current walls and foundations? There are a variety of elements which can impact and weaken the structure of your house.

  • House type -
    The potential of your house for a basement conversion Mayfair could be based on your type of property.

  • Geology -
    A local building control officer will help you decide if your property is appropriate for a basement conversion.

  • Water table -
    The water table on which your property is constructed will impact the structure selection and waterproofing of the conversion of the basement. If you have a higher level of the water table, without the water saturating the basement, you may not be able to dig as deep and it will cause more structural problems, making the conversion more difficult.

  • Ventilation -
    How much ventilation is needed in the current basement? Or how quickly will ventilation be applied to a new basement? Building Regulations say that with an opening for kitchens, bathrooms and utility rooms, you need to provide rapid ventilation.

  • Foul drainage, Groundwater drainage and damp -
    You would need to protect your basement from groundwater that is drawn into your basement if your basement is not already waterproofed, as this can lead to flooding and dampness.

  • Light -
    Lighting is important, but since basements are underground, they do not receive a lot of light. Installing a glass rooflight to ensure that your basement receives more light.

  • Height -
    Is your basement sufficiently high as it  should have a height of at least 2.4 metres. If your ceiling is lower than this, to build more space, you will need to dig a little deeper, which will make your project more costly.

    Enable insulation, lighting, ventilation, and plumbing to decide whether you need to excavate further down and whether your property is suitable for a basement conversion when considering the height of your basement.

  • Insulation -
    If your basement is not already well insulated, you will need to instal in all exterior walls and floors.

  • Fire escape  -
    An external door or window for escape in the event of fire should be built if your basement is transformed into a habitable room.
