These are the technical rules and regulations governing any extension building alterations you wish to carry out to a property. Although a modest extension may not require planning permission, it will still need to comply with the building regulation requirements. The Building Control Department of your Local Authority will be able to advise what is involved and, depending upon the scale of the work, you may decide to ask for help from a chartered surveyor or architect.
It has to be said Building Regulations can cause estate agents problems when we are asked to sell a property where, it later transpires, some aspect breaches the Regulations or the work was undertaken without the necessary approval.
Building Regulations cover such matters as the structural integrity of the work, the provision of services, insulation standards as well as health and safety considerations such as compliance with the fire regulations, etc. Sometimes retrospective consent will be necessary but, in extreme cases, remedial work may be required.
