Primarily office space, used all year round Mon-Fri 9am-6pm. I have considered electric UFH, but I am also slightly put off from our days in a flat where we seemed to be heating everywhere else bar the rooms we were trying to heat… having said that it was built from a converted maltings and wasn’t necessarily insulated well. Internal floor space, I am looking at 3m x3.6m, next to the boundary. Garden room will be full south facing on the shorter end which will have the Bi-Folds and I am considering triple glazing. The property to the east has a ground level 300mm lower than mine, and to the south is about 150mm. I am looking at maintaining the door threshold consistent with the garage which is one brick above my ground level, and putting a trench and drain round to deal with any residual rain water. We live at the top of a hill, so don’t tend to have issues with flooding. Frame to be 5” x 2” with a two 10mm flitch beams in to ensure spans at otherwise 400mm offsets. I think I can get away with a warm roof and am considering putting sedum on top of it. For cladding I was looking at Cladco’s composite and using their composite battening, mainly because to ease in maintenance.

Looks very nice by the way.

So I was looking at this and thinking how would you go about putting bifolds in. My guess now would be to strip foot the front to the width of the bifolds, and use some engineering bricks/blocks for the bifolds to sit directly on tied back to the slab through the EPS.

I realise this was a year ago, loving all the detail that was given. Just wondered how people dealt with the thresholds, especially if anyone had put in bifolds and how they sat them on the raft? I was looking at VuFold but they seem to want the frames sat at a maximum of 5-10mm from the front of the “brickwork” (Even our house ones (another brand) are 30mm back), which then means the outer EPS presumably would be load bearing? With bottom hung bifold did anyone put in a strip of Armatherm/CompacFoam/Other or is that simply far too much hassle and overkill?

Will be building a garden office and decided on a concrete insulated raft. There’s some interesting posts and wanted to ask a couple of questions regarding detailing with bifolds… so will head over to the threads and see what people have done.
