HI @ProDave according to their specs: "General Purpose Walling Durox Supabloc is recommended for general-purpose walling applications including inner leaves, solid external walls, internal partitions, and solid walls below DPC. "

Hi @PeterW roof 100mm, walls 75mm, floor 50mm this is the type of foundatin I plan on using I dont think anybody would be bothered to! I am commited on this! Regarding the footings I can prob dig another 10cm

50cm footings deep and wide, 100mm screed. FYI the thermal bocks are lightweight (6.3kg compared to 19kg for a standard concrete block),single skin, warm roof composition will be 11mm OSB top deck 100mm celotex 18mm OSB sub deck 220mm C24 joists

I want to avoid Building Control (less than 30m2), and come to think I was just greedy going for 8x6, if it wasnt for this Im sure the building would be already up!!!

Hi @ProDave thanks for your feedback! I already got the thermal blocks at a bargain (Durox Supablocs), they were literally free from some over order and they are already with me so cant go back on the building method! I think I did research the caravan thing sometime ago, would need a Lawfull development certificate too! @joe90 thank you, BC said "If the building was a garage the proposed footings would suffice, if the building is for another use full strip footings of at least 1 metre depth are required." By the way, this was back in 2018, hence why I gave up after getting the planning decision for the 8x6m garden room. Regarding BC visit, this would not apply as Im going for less than 30m2 internal area, what I was concerned was if LA would come for a visit and see us already raising walls! I want to crack on ! with the covid situation dont think anybody would come, seems everyone on my LA is working from home

Hi @joe90 this is what he said: "I have checked our guidance and this cannot be achieved through a Non Material Amendment application due to the difference in size" where would I be able to validate this I would not mind making the application again, its just the time it takes, seems a bit non sense as I have been approved a bigger one but to go smaller (isually going bigger is always issue)

HI @PeterW Thank you for your feedback (not only here but on most of my threads!). Im not looking to change the method of construction, I got the thermal blocks for such a bargain, they are just stored and ready to go. FYI the height of the building willbe about 2.65m

Hi all, hope everyone is safe and well. I am after some advice regarding a proposed garden office/room I would like to build. I have previously written a thread on this forum regarding a 8m x 6m garden office that I planned on building last year, howeverI ended up not going ahead with this as 1 - B.C. was advising for really deep foundations and 2- due to some other personal matters. However I am now in a situation where I have my mother in law moving in as she is elderly, and guess what, I am losing my work office. Im sure it will be great to have her with us, but I have no space to work now as I work from home. So I have made the decision to build a smaller footprint garden room (6.5m x 5m ) that falls short of requiring Building Regs, the internal area will be 27.5m2. It will be built with thermal blocks on render, warm roof and insulated plasterboard. FYI, I have been removed P.D rights. It will replace the current approved plans for the 8x6. So a little bit of history regarding planning, planning application for my build was approved back in 2016 (build completed in 2017), having an approved garage plan, for which I replaced with another one with increased footprint and height (Variation of Condition to replace the approved garage); this was approved in 2017, and then replaced again (with another Variation of Condition ) with the current approved garden office/room plan of 8m x 6m one with a flat roof. (you must have figure out by now I am an undecisive person !!!) ? I contacted the planning officer regarding my new proposal and questioned if I could make another variation of condition, he advised that I should make a full household planning application. He also mentioned that since it is a smaller size building we could not go through a non-material amendment. So I am a bit frustrated as a full planning application may take some time to be decided, as I am in a bit of a hurry to get my mother in law moved in. My question is, since I already have approval for the 8m x 6m garden room, is there a problem if I “start” with footings, and block walls while the other application goes through? “Technically” I have approval, obviously the footprint is smaller now, but would they come with a tape measure and look around if I am actually building a 6mx5m instead of a 8mx6m? Just looking for some thoughts on this! Again, thank you all for the help and feedback for the last 5 years or so!

Hello everyone, just updates! Paperwork sent to S.E. now waiting. Also got an very nice quote for Steico Joists, £980 Exc VAT but including delivery.

I did think the same thing, just left the option here so the forum can decide for me!! But the price difference with the posi joists compared to less work do make it attractive The quote also includes the gabble ladders, Im no joiner nor a specialist, but I believe these 2 would be for the overhangs on the left/right? If so, much easier to build

Ok I will call up and check Quick number crunching, I just had a local timber merchant return me a quote for posi-joists so have got in front of me 2 options for the main roof structure: Universal Steel Beam 6M - £423 Timber Joists - Structural Graded C24 Treated Carcassing Timber 47mm x 200mm x 5.4m (37x) - £851 Total: +/- £1274 (Inc VAT) Posi Joists: 6800mm (14x) + Gabble Ladders 6800mm (2x) + Framing Anchors (56x) Total: £1440 (Inc VAT) What would you guys say about this?

Correct if Im wrong...what length would the firring timber be? from what I understand they are long runs (max size I found was 4.8m)? Thick head me!

Good morning! I must be misunderstanding this completely...the joists are running over the 8m span, not the 6.....the slope would not be to the rear, but to either left or right?

I will try to figure this out still confusing to me (sorry for newbieness)

Yea, I see the point, what I have not understood is, where do the firring strips sit if my joists are going the other way I want the slope to be?
