How Does It Work?
The Base Room™ uses a method of construction tried and tested both in Europe and the United States. More recently this method was seen in practice on Channel 4’s Grand Designs. Insulated Concrete Forms (ICFs) are exceedingly robust but also very versatile. The outer casing provides superb thermal insulation, whilst the inner concrete core provides overall strength and deadens any airborne sound. Most of the structure (90%) is laid below ground with steps leading down to the new room but the final element above ground allows the introduction of up to 360º daylight. The Base Room™ construction allows total flexibility for windows and doors and the timber roof is strong enough to support a garden terrace with decking or planting. As for the internal finish, well that's up to you!

Prior to the undertaking of a Base Room™ project, a full site survey must be carried out; this is important for many reasons:
- To check the ground for any pipes or sewerage channels.
- To verify the space where the Base Room™ is to be built and make sure we are using the most suitable position.
- The initial build of the Base Room™ takes an average of 12 weeks, underscoring the importance of the initial site survey so as to minimise the effects on your home.
While any building project will necessarily cause a degree of disruption to certain areas of a property, The Base Room™ Company is fully committed to ensuring this is as minimal as possible. The use of specialised equipment at every stage of the Base Room™ project will guarantee that mess and disruption to your lifestyle and home is kept to an absolute minimum. The initial survey enables us to determine with you, the customer, the perfect course of action to suit both you and the project. A build-time of just 12 weeks confirms the value of this investment into your property.
