Guardian Home Modular Extension Turned into a Contemporary Kitchen

Building control approval for your peace of mind

Local Authority Building Control Registered Partner Authority Scheme Logo

Under certain criteria, the Modular Home Extension System would be exempt from Building Control approval - however, we strongly recommend that approval always be sought.

But, as the Modular Home Extension System carries LABC / LABSS certification, the Building Control process should proceed faster, smoother and without complication.

Local Authority Building Standards Scotland Logo

Due to the high performance insulation and with Building Control approval, the Modular Home Extension System, may allow the removal of the wall between the house and conservatory, providing the flexibility to extend and enlarge an existing kitchen, living room or bedroom.

In compliance with LABC / LABSS, the Modular Home Extension has a ventilated roof.

Slots in the ring and ridge beams allow air to flow freely through the roof thereby avoiding condensation and allowing any moisture to exit. With many unproven roof conversions, moisture can form inside the roof causing staining and mould growth to the internal plasterboard, leading to deterioration or even failure of the roof components.

Get it Right First Time

Building work of any kind can be a daunting process.

Don’t be persuaded to go for an unproven, cheap wrap-over option which will cause you problems and cost you money in the long term.

Our Full Service Package is the hassle-free way to achieve the Home Extension you want. Tatchell's will manage your project and keep you informed at every stage, providing a seamless process from your original enquiry, through planning permission to final installation and certification.
