I'm looking to build above a single skin garage and I'm wondering if anyone can help, who perhaps has experience of this and can provide any photos of diagrams.
I've done some research into the possible structural solutions for this and the common replies tend to be:
1. Knock it down and restart
2. Using steel on pillars (however, I've been unable to find any diagrams and images showing this in any detail).
My single skin garage looks like this from the front (columns at corners are 1x1 bricks)::
From the back it looks like this (columns at corners are 1.5x1.5 bricks):
The existing raft foundation spec is this (main width and depth of the foundation is 600x600mm with 150mm slab, 50mm sand, 150mm compacted hardcore)
I'd like to look at options of building on the existing foundations and leaving the following existing brick structure:
The reasons for this are:
- There appears to be sound external brick with 4 good pillars, one at each corner.
- The existing garage door can remain/be reused
- The existing front door can be reused and brought forwards (for a longer hallway)
- Cleaner and less disruptive building works
I'm interested in feasible loading bearing methods to have a timber frame dormer roof (with around 1m high timber wall needed) on top of this and which methods would be best. This is my rough proposed design. I'm assuming a lightweight cladding and I'm hoping for the main frame to level to the edge of the remaining brick below.
I'm assuming the following are sound areas for load bearing points (2 pillars at front, 2 pillars at back and appropriate connection to the side of the existing house):
