All extensions and most conservatories require a Building Warrant in Scotland. Conservatory means a building attached to a dwelling and having an external quality door separating it from that dwelling and having not less than three-quarters of the area of its roof and not less than one-half of the area of its external walls made of translucent material.
A small conservatory with an internal floor area of under eight square metres does not usually require a building warrant.
A sunroom with a solid roof (either traditional tiles or modern lightweight material) has different rules and the light and ventilation of the adjoining room has to be taken into consideration as well as thermal properties of the building. This also applies to replacing a conservatory roof with a solid roof.
Cutting away a new hole in a wall to form a window or doorway also requires a building warrant.
The building warrant confirms that the proposed work meets the requirements of the building regulations and it is a legal requirement for you to have a building warrant before any work commences. The building standards process gives you permission for the design and construction of the work and the building regulations make sure that the work meets minimum building standards.
ERG Scotland can advise and guide you through all the stages of obtaining a warrant, arranging inspections during the work and obtaining the completion certificate at the end of the project.
