Put simply, building regulations Part A is focused on the structure and stability of a building. Essentially, it’s there to ensure that the building stays upright, even in the event of any impact.
It’s focused on ensuring that the foundations of the building can deal with the ‘load’ imposed by the structure itself. The strength and stability of the ground in terms of supporting the foundations and the structure is also covered.
There are two main principles to Part A (though obviously the regulation itself is very in-depth):
Other notable points
The full document is 44 pages long, so we’re obviously not going to cover the whole thing here. However, we’ve been able to pull out the main points that relate to skylights.
Openings, recesses, overhangs and chases
It’s a legal requirement that the number, size and position of openings and recesses should never affect the stability of a wall or the lateral restraint afforded by a buttressing wall to a supported wall. Essentially, any opening must not impact the stability of the property.
(Though less relevant to skylights, it’s also worth noting that no openings should be provided in walls below the ground floor except for small holes for services and ventilation.)
Small single-storey non-residential buildings and annexes
In these properties, one or two major openings of not more than 2.1m in height are permitted in one wall of the building or annexe only. The width of a single opening or the combined width of two openings cannot exceed 5m. The only other permitted openings in a building or annexe are traditional windows and a single leaf door.
Section 4: Roof covering
This is the main section that could potentially impact on skylights, as it applies to the roof area, so we’ll go through the relevant points here:
(It’s worth noting that we’ve not covered 4.2 and 4.6, because they aren’t as relevant to our topic and – in the case of 4.2, it’s actually just a note about the other clauses under section 4!)
