    Volumetric Concrete....

    Hi, I'm coming to the point where I will actually need to get some concrete in. I like the idea of volumetric concrete so that I pay for what I use. I need about 1.2 cubic metres of concrete and will have to barrow it. Having phoned a few people up there seems to be a big difference in price...

    I am planning on building a couple of garden buildings, one 30sqm, and another smaller 'practice shed' that is around 9sqm. Both are on a hill, the smaller building on a steeper bit of land than the larger one (which is flat-ish mostly). Due to the location, materials have to be transported by...

    Securing wood in concrete

    I want to lay gravel over a section of my garden, but need to add an edge to stop the gravel travelling. I’ve laid some wooden battens into mortar (with a gravel bed underneath for drainage) and use screws about 1 inch proud in the under side of the wood to make them more secure in the concrete...

    There's a stream in my house

    Hi. I have just purchased a terraced house. Built circa 1890. It's in a row of 24 houses built on a relatively steep hill. The houses are built in pairs. Each pair is lower than the pair before as they step down the hill. I'm near the bottom. I'm situated so that, looking at the house, the house...

    Foundations for my outbuilding

    Hi all, I hope you are well. I'll try to keep this short. I am building an outbuilding (hopefully to use as an office / gym). The size is approx. 7m by 4m. It is being built on the boundary so within 1m. I plan to build it all of the light breeze blocks (except two rows of bricks at the...

One structural engineer has suggested pad and beams as being the easiest and most cost-effective solution, whilst another has said we...

    Extension Foundations

    Hello I’m looking at putting a single story extension on my house (roughly 4x4m). I’ve had a foundation inspection on my property and the foundations are about 3m down and are of raft/pile formation. Mu question is do the foundations of an extension this size need to be the same as the house?
