Hi, we're about to do an 8m x 4m 2-storey extension and have an oak tree 4metres from the proposed extension flank wall. We're also on heavily clay-based soil. One structural engineer has suggested pad and beams as being the easiest and most cost-effective solution, whilst another has said we...

Hi all, I hope you are well. Just looking for anyone's opinion on these cracks. Both cracks have been here since we moved in and after filling they have recently began to open again 18 months on. The first crack is against the join in the wall and runs vertical up the wall between the join. It...

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?

Morning, I'm wanting to build a summerhouse, and keen to find out all I need to know before starting. The plan is to build something 3mx4m, with the highest point of the roof being <2.5m high. The site is not very level, a few inches drop from one end to the other, and can get very damp in...

Hello, I am hoping to build a summer house/shed combo at the bottom of the garden. I am hoping to build it myself as I won't be able to find something off the shelf that will meet my requirements. It is going to be one big building with part of it serving as a shed and the other part a summer...

I hope that someone can help me. I am partway through constructing a close board fence next to my new single skin garden wall. The previous fence was posts and panels some of which were bolted into the wall, these recently took out part of the wall in a storm. Have got half the fence done...

I’m doing a rear extension on my bungalow, the floor is going to be block and beam. My question is... where the beams key into the existing cavity wall, do they have to knock through so that they sit on the inner load bearing skin? Or can they rest on the outer skin? any advice would be...

Hi all, Embarking on a small extension on the back of the house. No knocking through required, just using existing window and door openings. I've spoken to BC for some of the technical info, and am intending on doing a chunk of the work myself as much as possible. My questions are as follows...

HI All, Somewhat of a random question so don't shoot me for asking! I am building a retaining wall to form a driveway next to my house (its about 6m from the house). The height being retained is about 1m in existing made up ground forming a bank to the field next door which is about 1m lower...

Morning We have just commenced the build of an orangery off the back of our property. The plan and quote was to have a 7m x 4m beam and block base with an air gap of around 150mm, so a fair bit of excavation. However when the builder turned up he suggested a slab as it worked better with the...

Hi - I am applying for a build over agreement with Thames Water to build over a sewer. They require "Existing" and "Proposed": a) Cross-sectional foundation plan b) Ground floor plans How do people usually determine the existing foundation plan? Do you actually dig down until you see the...

Can anyone tell me how far, very roughly, the concrete generally projects from the face of an underpinned wall please? Been digging a small trial pit to expose the foundations of my neighbour's Victorian flank wall, as I need to build some new footings adjacent to this, and have exposed some...

Hey guys, I am working on a new construction home in Colorado and have done most of the drawings myself. I really love a slab floor and it is one aspect I don't want to bend on. Most of my professional work is in concrete and the home has a lot in it. All of the exterior walls are full height...

He'll, Need a bit of advice. I'm building a porch (well doing some of the donkey work to save money). I've gone down 900mm, but about 20cm from the bottom the electric cable runs thought it perpendicular at the front of what will be the porch. My builder friend says dig a few extra inches down...
