Garage Constrution

    Hi, soon will be digging out for garage. Is going to be 11m x 7m, with 2 roller doors. Hoping to save costs by building it myself. For this reason i was initially thinking of going timber frame, but after costing for studwork, osd, membrane, battens and tongue and groove board, i thin simple block will be cheaper. My question though is on block size.

    What size of block and block layout should i be going with? Door openings will be 10 feet, roof contains a loft. Would regular 4 inch block be a bit skimpy? Was thinking it may need to be 6. No need for a cavity so single course will work fine i think.

    Any help, advice, experience would be greatly appreciated!!

    4 inch blockwork is not structural and will not be able to support any weight. You should speak to an engineer to be exact but I would guess 9inch would be the way to go (block on flat). You may need to put in a band beam depending on size and also a steel beam for the lintel over the ope. Get engineers advice to be sure as you dont want it to crack or move.

    9 inch seems a little overkill to be honest, county is full of 4 inch block garages, I was only thinking 6 to allow for the loft and long roof.

    Any other opinions or ideas?

    and I have visited a good quantity of them which have fallen or moved with the strong winds we had at the start of the year.

    I'm looking at this from experience and not a structural pov. 4 inch (block on edge) is a non runner for anything over 6 block high garden wall with piers.
    6 inch block on edge would still scare the sh1t outta me for what your talking about.
    9 Inch, or block on flat is the least I would consider.

    100mm (4") block walls alone will not be enough to withstand the loads of a roof of that size with a loft.
    150mm (6") block is unpopular with blocklayers in terms of coursing etc. and may be difficult to get.
    215mm (9") may do the job, but if you're going to use that many blocks why not build a cavity wall and leave yourself the option to insulate either now or later - I know you say you don't need it. but the option is good to have. Don't skimp on structure anyway, and as has been said, if you're unsure run it past an engineer. My guess is that a building with that plan area, no internal walls, a pitched roof and 2 large door opes will need some sort of structural design input.

    here ends the structural conversation. we cannot offer structural advice here. See the forum charter for clarification

    Sorry but I never raised a structural question. I am a qualified engineer and I have no issues with either timber frame or 6 inch block construction taking the load. I am not a builder however and my question was on possible construction methods for a self build. I was hoping to get people's experiences on such a project as I have none. Ideally I would be more comfortable building a timber frame but from what I can see, this would be a more costly option. I was considering a steel frame structure but the cladding and sealing is the most expensive part of the framing so I don't think I would save anything going that way
