    Self build shed opinion

    Im looking to build a shed 2.4mx1.0m so it fits into a small awkward space in the garden. It'll be a pent roof sloping rearward with double doors to the front. I fancied the rustic look whilst keeping it watertight. My plan was to use 3x3 fence posts for the uprights on each corner with a...

    Although I'm sure this should have been done differently, and I suspect there might be several wrongs in it, rather than start all again I need to rectify it so that I can finish the chipboard floor to the door opening. Suspended timber floor which is bolted up to the inner leaf. Top of the...

    I have a 60s house with an internal chimney through the centre of the building. Strictly, i'm not installing a wood burner, as i'm putting a gas wood burner style Yeoman CL3 in there. Having knocked the old one out, and pulled away the plaster, I can see that the lintel is doing very little...
