Workshop build

    I now rent 2 of these workshops and am taking out the concrete wall to make one big one.

    We are taking on someone and need the space and desperately need an office.

    My biggest question is, I want a small mezzanine but I need it floating as I need to drive vehicles under.

    My question is, is it possible to do this.

    Here is an old photo when we moved in and put a ramp up:

    Here is a rough drawing:

    Of what I want to do.

    And here is a drawing facing the shutter

    Is it possible to do some steelwork that will be strong enough to support it?

    The unit next door has a full mezzanine at standard staircase height and it's great but I can only go half as I need space for the ramp and tall Van's.

    If I cant do it will angle, I will have to put three steels? Or timbers? Inline with the left ramp post or just to the side touching and then run a beam across.

    Can the 30ft beam be timber?

    I know I need to get a professional in and that's not a problem just wanted some ideas first.

    I really want the spraybooth as well but if it is too tight then so be it.

    We want a year out of this place then move on to a bigger premises providing it all goes well.

    On the wall at the back we will be setting up cupboards and tool chests.

    I think the compressor will be best on a platform above the ramp as it's out the way and we can access it on the mezzanine to get to the compressor if needs be.

    Worse case it will just go in the back left corner on the mezzanine.

    Won't be spanning 10m in timber cheaply. 5m would be 9x2 doubled up and they may want a flat steel inbetween.

    First port of call would be a structural engineers mate. Building its easy enough but need the calcs.

    10m in timber would need to be a glulam beam , most likely flitch (steel) in between as stated above depending upon load and much much dearer than steel

    If you get building control involved it would escalate with them wanting floor core samples of the concrete and sub floor for load bearing of the stanchion position s

    Ok cheers. There would be a pillar in the middle if we did 3 uprights.

    I'm guessing then that having it floating will be a no go?

    as reference

    however a quick question whats at front in the space where 18ft area is it free there

    and i wouldnt build it where your ramp is as some vehicles are longer

    you could also build the structure frame easily and build it in wood beams

    this is certainly passable by the council

    Does your lease allow what you are looking to do ?

    Yes all allowed.

    Do you think that the "floating" idea with the steel angle bolted to the wall will work or can I just use 3 upright supports either timber or steel at both ends of workshop and one in the middle?

    the steel angle you will fail with if your still doing it in the 7ft area consider bolting a wood beam to the wall

    if only using as an office area and you keep the weight to a minimum office table and chairs and a seating area for dinner you shouldnt need to add further strength either side or in the middle against the wall but if you want to do use 3" box section with a flat top plate and a plate to fasten to the wall mainly for beam strength you will need 3 of these made up

    upgrading to a thicker I beam/rsj and fitting a wood beam to the rsj this will need to be drilled out so you can bolt the wood beam to the steel beam

    then wood from the wall to the steel beam and floor it out a wood frame can then be built on top of the steel beam to make your office up

    you would need concrete pillars built up either side for the steel beam to sit upon

    its also the cheapest option for you

    staircase up one side of the frame but you also have to consider head height and also a platform area cant use a staircase and then straight into you office area due to safety aspect

    Have a look on eBay for used mezz floors.

    Bear in mind if the council find out your rates could go up.

    Also bear in mind EN 1090 if doing it in steel and your insurance. Particularly employers liability. God forbid an employee has an accident. They’ll do anything to get out of it.
