Flats, Commercial, Public & ‘Other Residential’ Buildings
LBC (SOUTH) works with London Building Control Ltd, Corporate Approved Inspectors, who are one of the leading providers for certifying buildings under the Building Regulations. Together we have many years’ experience in the industry working on thousands projects.
The following notes concern building control for Flats, Commercial and ‘Other Residential’ – nursing homes etc.
For domestic buildings: extensions, loft conversions and houses- see the Residential Building section.
Public buildings, such as Schools and Health Care usually have their own government guidance which should be followed.
Houses in Multiple Occupation (HMO’s) with over 6 residents should follow the guidance below; where there are 6 or fewer residents it can be treated similarly to a house.
For ‘Commercial’, ‘Public’, ‘Other Residential’, HMO’s and work concerning the common parts of ‘Flats’ a consultation will need to be carried out with the Fire Authority as these also fall under separate legislation which is enforced by the FA (the Regulatory Reform (Fire Safety) Order 1985). The RRO controls fire safety in the workplace, including means of escape and access for fire fighting and vehicles. Particular attention needs to be given where there is sleeping accommodation : smoke detection and smoke ventilation of common stairs and lobbies will usually be required. Likewise basements and carparks will need particular care and may need additional ventilation.
Commercial buildings will require SBEM thermal calculations (with a Target Emission Rate compared to the Building Emission Rate). Flats require SAP calculations and associated Energy Performance Certificates at end of works. Air tightness tests will be needed for new buildings as part of the energy assessment.
Access for the disabled
Access and facilities for the disabled also need to be considered in some detail, often with an access statement, covering the provision for disabled toilets and facilities (showers, changing rooms, lowered counters etc). Wheelchair refuges by stairs may also be needed where users can await rescue in a fire. Additional ‘optional requirements’ may also be required under planning for new dwellings.
Acoustic testing is needed for flats and ‘rooms for residential purposes’ (such as hotels, residential care homes and HMO’s with more than 6 residents).
Often structural calculations are needed in support of the design – such as for steel columns or beams, or foundations etc.
