The dormer loft is built vertically on top of an already existing sloping roof and requires relatively simple building works.

Hipped Roof

A hip end is the sloping end to a roof and a gable is the triangular section of wall which stands between two sloping roofs.


Roof with sloping window pointing towards the sky fitting to the roof-line and leaving the original roof structure untouched.


Located to the rear of the home, with a flat roof type and back wall sloping inwards at an angle of 72 degrees.

Certifications Completed

Once the loft conversion in Archway or Highgate has been finalised and has approval from building control, our team will present you with a folder that includes every key document related to the project, such as the electric and gas certificates, the building completion certificate, manufacturer's warranty and instructional documents, as well as a 15-year structural warranty.
