We Provide A Comprehensive Loft Conversion Service That Is Fully Inclusive

Your loft conversion in Harringay starts with a member of our design team providing an on-site assessment to help with all of the various aspects involved in planning application and architectural drawings.

Why Our Building Company

Dedicated Project Manager at N4, N15 and N8

Regular Building Control Check in Harringay and Crouch End

Inspections are carried out regularly by your building control officer over the course of your loft conversion project in order to ensure that our work is compliant with all of the most recent building regulation requirements.

After we have completed your loft conversion in Harringay, your building control inspector makes a final visit and a completion certificate is issued.

All Relevant Certificates Provided For Your Loft

Once all work is complete, an approved building control inspector will provide you with a completion folder that contains all of the relevant documents, including the electric, gas, and completion certificates, as well as all of the manufacturer’s instructions and guarantees, along with a certificated 15-year structural guarantee.

Work Not Contracted Out

You can rest assured that we do not ever contract out. Therefore, throughout the entire course of your loft conversion, you will have the same experienced team at all times.



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.
