Why Our Building Company

Dedicated Project Manager in EN4, EN5 AND NW7

The project manager is the first point of contact and manages the project alongside you by providing information about the happenings on the job site and ensuring that everybody stays connected. He also supervises and reviews the progress each week, ensuring that it moves forward as planned.

Routine Building Control Checks

The building control officer will perform regular inspections throughout the Barnet’s loft conversion project to ensure that the work follows the latest building regulations. Once the loft conversion is complete, the building control inspector makes a final visit before issuing a certificate of completion.

All Relevant Certification for the loft in Barnet

Once the work is complete and building control has approved it, you will be provided with a completion folder containing all relevant documents, including the gas, electric, and completion certificates, as well as all the manufacturer’s instructions and guarantees and a 15-year structural guarantee certificate.

No Subcontracting Work

You can rest assured that we will never subcontract your work, which means that you will always have the same team of experienced professionals on hand throughout your loft conversion in Barnet.



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.

Having gained a lot of experience in converting lofts throughout in areas such as north London as Highbury, Harrow and Finchley, our team of loft specialists have a good understanding of all the components required to create the ultimate loft space.
