    I'm looking to put up a large garage / workshop for personal use on land to the rear of my house.

    We have a garden, 200ft long and 19ft wide and I have had 30ft of that concreted to 1.5ft deep with reinforcement.

    I am hoping to build a steel framed building, clad with metal corrugated sheet over wooden purlins. The frame would be built for me and CE certificated.

    My problem is ascertaining what i can build within planing regulations.

    I have a fence either side for my neighbours which is the official boundary/curtilage I am working to.

    My reading of permitted planning section E leads me to believe that I can build within 1m of this but the building must be made of 'non-combustible materials' which I should think steel is under the blanket of.

    Eaves height seems to be safe at 2.5m but I am unsure what the height of the roof would be allowed at with respect to the boundary distance. It reads at 3m for a single pitch or 4 for an apex but is that considering the boundary?

    Also the floor area permitted.

    I was looking at a 9mx5m floor area but it reads that only a 30msq floor would avoid building regs.

    Any advice very welcome.

    Combustible materials is a building regulation requirement, not Permitted Development.

    You can build right up next to the boundary if you like. But if any part of the outbuilding is within 2m of any boundary, you are limited to a maximum of 2.5m to the highest point of the roof.

    If you want to go higher under permitted development (up to 4m) you need to ensure any part of your outbuilding is set 2m or more away from the boundary. Any breach of these heights near boundaries would mean you need full PP.

    Building regs aren't onerous for a garden outbuilding- hopefully you've got some pics of the hole in the ground before you poured an excessive amount of concrete in it.

    Planning permission - have a look on your local councils' planning portal, see if you can find any similar applications. And have a look in your neighbours' gardens - if anyone else has similar chunky structures you'll probably meet less resistance from planners. Again PP is not difficult or particularly expensive.

    Regarding your structure, tin sheets can end up giving you massive condensation problems, as well as being v cold in winter and v hot in the summer. Depending what you're planning on doing in there you might want to think about other options. And (if this is one of those ebay offers) check very carefully what is included in the price

    My neighbour a few doors up has a massive self built structure which is way above the regulations and he didn't apply for planning permission.

    I had a planning officer around when I tried to put up a wooden framed building (never even got the frame up) who informed me that it was the wooden construction that was the issue so it had to come down.

    What I need is a decent car workshop (not a garage per se) - but the kicker is I need to get my campervan in and out of it (through it if possible) - at 2.4m thats hard when planning only allows a 2.5m height.

    I've looked at concrete sectionals (major hassle, weight), steel frames (industrial, overkill) and metal kits (flimsy, insecure, pricey) and still no wiser. I'm happy to try and meet the planning regs but they aren't friendly to anyone wanting any height or width on a narrow plot.

    Lower the floor slab below ground level by about 450mm and have a small steel portal frame structure. Or better still have the entire thing below ground level with a big sliding door and ramp like Thunderbird Island.

    For the height you want its either the Thunderbird solution (which I contemplated a while ago & does appeal) or go the PP route. Structure- Breeze blocks would get my vote. Your height restriction is a feature of PD- if you go for PP you can apply for the height you want subject to normal planning criteria about overbearing.
