New Garage

[J5]

How do
We are in the process of making a double length garage; car at the front, workshop at the back. I've been looking at the previous posts here and looking at this interactive doodah...

The old garage was in two halfs, brick at the front end and concrete panel extension at the back (on a concrete base). Total floor 27 square metre-ish. The concrete panel section has been knocked down already. The new garage (30sqm ish) will in effect be further down the garden as it will start where the old brick garage finishes. The brick bit will be knocked down once the new garage is in place.

1) We plan on reusing the concrete panels for the new garage (we have a stock pile of extra panels that the previous owner left behind). The only problem with building regs that i can think of is that the garage is on the the boundary and not a metre away as required if the floor space is greater then 15sqm... but the old one was on the boundary too so not sure if thats ok, seeing as the new garage will be about 5m further down the garden?

2) On another note. The old concrete base sits about 9" above ground level. We have cleared the ground around the old base as far as we wish to extend. We have a huge pile of building rubble from another job (mostly whole bricks), can we use this anywhere in the new base at all? Either as sub base or chucked in the concrete itself. Also, should we be tying the old base to the new base somehow?

A thousand thanks in advance.

Concrete panels are non-combustible, so no problems there with b/regs and boundaries

You rubble can be used as hardcore if broken down into 1/4 bricks and less (no voids) but not in the concrete as they pieces will be too big.

The slabs can be separate. But form a proper butt joint and seal it afterwards

Thanks for the info.

Ah yeah, combustible-ness, that brings the question of what to make the roof out off. The old garage was that see-through corrugated fibreglass sheet (like a glass house in the summer). We were thinking of doing a flat roof and then felting it, is that too much timber for the regs or is there something better we can use on a flat roof?

Previously it looked like they had attempted to seal the gaps in the slabs with tar but thats nasty to work with diy style. I was considering expanding foam or buying silicon sealant in bulk lol. Any better suggestions?
