The Ultimate Guide to Basement Conversion
Having more space or an extra room has proven to be very useful, which is why basement conversion has become increasingly popular. You can transform an unused basement into a beautiful living space without spending a fortune. However, basement conversion involves several processes, and this guide will cover all of them.
How Much Time Does a Basement Conversion Require?
The time needed for a basement conversion depends on your requirements and the size of the space you wish to utilise. Converting an existing room in the cellar using a waterproof membrane cavity system typically takes about three weeks, including sump digging and pump installation. However, converting and extending the cellar can take several months. The best time to carry out a basement conversion is during the summer.
Planning Permission and Building Regulations
Before proceeding with a basement conversion, you need to check with your local authority to determine if planning permission is necessary.
1. Planning Permission for Basements
In most cases, planning permission is not required for converting an existing basement or cellar. A simple ‘change of use’ is sufficient. However, if you plan to build a new basement, extend an existing one, or add a light well that alters the exterior appearance of your home, planning permission will be required.
2. Building Regulations for Basements
When converting a basement into a living area, you must obtain Building Regulations approval. This ensures that your basement is energy efficient and suitable for habitation. Building Regulations cover aspects such as fire escape routes, heating, ventilation, ceiling height, waterproofing, electrical installations, and water supplies.
Basement Conversion Costs
You don’t need to spend a fortune to carry out a basement conversion. The costs typically include:
- Flooring
- Heating
- Waterproofing
- Decorating
- Lighting
Things to Do Before Carrying Out a Basement Conversion
Before converting your basement or preparing for waterproofing, consider the following steps:
- Clear your basement: Remove dirt, dust, and debris.
- Check the walls: Look for any damage and fill holes or dents before proceeding with the conversion or waterproofing.
Heating a Basement
To create a comfortable environment in your basement, you must ensure it is adequately heated. Several options are available, depending on your needs and budget:
- Underfloor heating: This is a popular choice for basement conversions. It is typically installed in screeds over waterproofing membranes, providing even heat distribution across the floor.
- Radiators: Installing a radiator is another effective heating method.
- Electric heaters: While plug-in units may not be the most cost-effective option, they can offer a temporary solution.
- Oil heaters: These are portable and often cheaper than electric heaters.
Insulating a Basement
Insulating your basement ensures your home is more energy-efficient, helping you save on heating bills while creating a moisture-free, habitable environment. Insulation is usually installed when constructing a new basement rather than retrofitting an old one. Focus primarily on insulating the walls rather than the ceiling. Some affordable insulation options include:
- Blanket (batt and roll) insulation
- Foam board insulation
- Loose-fill insulation
- Sprayed foam insulation
Ventilating a Basement
Proper ventilation is essential for converting your basement into a habitable space, allowing fresh air to circulate and reducing humidity. You can achieve ventilation through windows (if available), staircases, fans, vents, and ventilation units.
How to Waterproof a Basement
To effectively waterproof your basement, you should be familiar with the various waterproofing systems available. The three main types of basement waterproofing systems include:
- External waterproofing
- Tanking
- Cavity drain membranes
Conclusion
Carrying out a basement conversion can be straightforward and cost-effective if you follow the necessary processes. By utilising the information discussed in this article, you can ensure a smooth and efficient basement conversion.
