When I move I am thinking of building a garden office so I don't need to use space in the house for that.
I'd like to use Celcon 630 x 215 x 100mm blocks for speed of construction, and once I have the 1st course level and plumb I believe it is very easy to keep that all the way up using thin joint mortar. It will be below 2.5 meters tall, and will be no more than 12 sqm max, and it will be a simple rectangle shape. Single double glazed door, 2 double glazed windows, then metal studs inside for walls and floor, and insulated using the closed cell spray foam, similar in ceiling. So I think with the Celcon blocks and closed cell insulation I have the thermal and acoustics covered, plus vapor.
The one thing I am unsure about is is the 100mm wide blocks, will that be stable enough?, i.e. I don't want it falling over? I also don't want to build piers as it will be pretty small anyway. If it does need to be shored up somehow I was thinking 40x40x4mm hollow box mild steel posts at each corner going about 1 meter into the ground, and these would be filled with concrete for extra strength, then I'd notch out a 40x40 space on the blocks at the end so they go aroud the post, alternate this on each course so every thing is tied nicely to these posts, I'd then probably add 1 more down each side, offset from each other. Probably also tied the top together with the same stuff so the roof can rest on that, which is just a simple roof with a slight gradient for run off. Then render the outside with a waterproof through colour render.
Any of this feasible? Or is there a more simple way of make sure it doesn't fall over. I'm not too worried how long it takes, as I can take my time. I just want to make it nice looking and secure
Also, I'm pretty sure I don't need planning permission, but I would like a building control cert if I ever sell the house.
Also, the garden is about 120 smq, so it is pretty small with regards to that.
Also, example of what I mean by the notches, and steel posts, I think this should tie all the walls very nicely together, and add a lot of sheer strength.
