How 10 day extension (Guardian extension) is built video 



3 steps to your 10 day extension

Step 1 – BASE

We have two styles of foundations for extensions, QuickBase and Durabase. Pile style foundations are versatile and have been used on small extensions to skyscrapers. During your home visit, we will analyse the area for the intended extension and recommend the best option. We can also do traditional wet based systems.
Benefits of pile base systems are that they are quicker to install, more cost-effective and can be constructed on difficult foundations making it a perfect option for many homeowners in Bristol/ Bath.

Step 2 – WALLS

We use Kingspan TEK panel system for the walls of your 10 day extension. High-specification, highly energy-efficient wall system which has proven itself as an industry leader in pre-fabricated walls. With a wide range of wall options like bricked and rendered makes it suit your home perfectly.

Step 3 – ROOF

Guardian Warm Core Roof is an insulated tiled roof system with an aluminium structure that is lightweight enough to be installed on conservatoires.
