Double up • Double storey • Second Floor
If you’ve run out of space, going up in traditional brick and mortar may not be a viable solution as your foundations may not be designed to carry the extra load. You may also not be ready to move out and have concrete works in your home for an extended period.
However, there is a solution. Lightweight dry construction that complies with every aspect of the national building regulations and approved by your local council.
We don’t remove your ceiling during the construction process and only disrupt you at the point where we built the staircase to connect the top and the bottom floor.
Mezzanine Floors
Do you have a big double volume space that’s wasted? A Mezzanine floor may be just the solution for you.
