Frequently Asked Questions
As a rough guide a Dormer conversion can start at £28,000 and a Velux conversion at £18,000, however prices can vary due to the size of the conversion and complexity.
Yes. If your conversion is for habitable accommodation then it needs to be planned professionally to ensure it confirms to stringent building regulations, Top-Storey have the own drawing office, where our technical draughtsmen will produce your plans to the highest standards and specifications.
Under regulations that came into effect from 1 October 2008 a loft conversion or small dormer extension is considered a permitted development, and generally does not require planning permission. Permission is required if you plan to extend or alter the roof space more than specified limits and conditions:
Volume increase of 40 cubic metres for terraced houses or 50 cubic metres for detached & semi-detached houses. No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway (i.e. no dormer to face the street).
No extension to be higher than the highest part of the roof Materials to be similar in appearance to the existing house (i.e. in keeping with the house and street). Side-facing windows to be obscure-glazed; any opening to be 1.7 metres above the floor. Dormer extensions, excluding hip to gable dormers are set back, as far as practicable, at least 20cm from the eaves. Roof extensions are not permitted development in designated areas, i.e. National Parks, Conservation areas, World Heritage Sites.
However the majority of Loft Conversions including those with quite large dormers do not require Planning Permission as the development can be completed under Permitted Development Rights.
