extension

Evening, I’ve been thinking about extending my cottage for a few years, the house was extended in the 80s to add a kitchen and very small bathroom, annoyingly it was only to about two thirds of the area it could have been. I’d like to “square off” the current extension, add a nice family...

Roof type: pitched, tiled roof over a kitchen extension. Issue: there are two square gaps in the insulation between the skylights, each roughly 400–450 mm on a side. The gaps are clear openings in the insulation (not just compressed or thin spots). My question - Is there any valid reason a...

We had a double storey extension completed around 4 years ago. About 6 months after some cracks started appearing on the plaster which we put down to settlement. Now however there are a few more upstairs with gaps and I'm a little concerned. Are these anything to worry about? The kids do slam...

Has anyone here been through the process of obtaining joint names insurance (C and C.1) for an extension they are adding to an existing house? This is a requirement of the JCT contract we are using, and I'm curious as to the costs that people have paid for this. If you have been through this...

I have an outbuilding in my garden already, I'd like to make a small building to the back of the existing one and "connect" the 2 together. The reason for this is so that I can take a door out of the wall and have access to the new room behind. The new roof will be flat and the existing one is...

Hi all, We are doing a 6m deep rear extension and could really do with your thoughts _/\_ Our adjacent (party wall) neighbour currently has a 3m extension with pitched roof. We are looking to match the neighbours pitched roof (with pitched internal ceiling below) and then transition to flat...

Hi everyone I am going to prepare and lay the concrete floor to my extension myself. I will need to run a pipe under the floor to provide ventilation to the existing suspended floor. I have already laid down hardcore and sand. I wanted to do the concrete slab first and then the...

I am in the planning stage of a single floor rear extension with a flat roof. The extended space is everything below the green line shown in the attachment. The oil burner is currently positioned in red circle 1. For added context, but not critical for the help needed here: as you can see...

Hi I have recently moved into a 1930s bungalow which had a single storey with extension added in the 1970s. At first I noticed a crack that runs along the join of the extension to the main house at one corner which is both external and internal. Also recently though I've noticed the floor bumps...

Hi, we are getting close to digging footings for our single storey extension and am finding information on party walls confusing. All of the diagrams I have seen demonstrating the 3m rule are in relation to the adjoining property horizontally and not when the new wall is perpendicular to the...

Hi I've recently moved house into a 1920s bungalow. An excellent extension to the kitchen was added in the 1970s and I've noticed a crack at the corner of the door where the extension meetings the main house. The crack is both external and internal. I'm in a real panic that it's bad structural...

Hi, We live in a busy city where space is limited and have a bit of an odd shaped house, we’d love to extend it somehow but the orientation/layout makes it a bit tricky. I’m hoping someone out there might be kind enough to offer some advice! We’re a semi detached corner house, originally it was...

Need a (partly) insulated room as an extension at the back of a link-attached single garage. The area is currently covered with not very even garden tiles (ants and old hedge roots are to blame). No building DIY skills. Does not have to be same temperature as the house, just protected from the...

Hi First timer on the forum. I'm sure this question has probably been asked before - but I couldn't find it anywhere. Im building a standard single storey extension and all of the specs / drawings I can find online - show a typical construction of 12.5mm Plasterboard 40mm Celotex TB4000...

Hi, A confusing one. For our knock-thru and main steel at rear of house, our SE has specified insitu padstone as follows through onto the new extension wall (steel actually only 100mm dimension now, not 250mm): The builder has produced this with a day to go before steel installed! we...

Hi all! I'm soon going to have my kitchen extended by knocking out the external wall. The work will also involve sanding down an artex ceiling (we've checked and there's no asbestos, luckily). However, I have a dust allergy, and I'm worried about dust from the work in the kitchen getting all...

I'm on the verge of getting a house (or my other half is anyhow). It's a small semi, but with enough space for a decent sized extension. The plan is to extend to the side, the existing foul waste routes from the rear around the side and off at an angle to a newish sewage treatment plant(STP)...

Afternoon all. I have a dormer bedroom, built into a hip roof under what looks to be permitted development. There is a 2x2 m stone column, from ground level all the way up to the eaves of the hip roof which contains two stacked bathrooms, one for each flat (ground floor and first floor) which is...

Hi Looking for some advice... So I have a dormer style house (common in suburban areas in the UK) and due to lack of space to the side of the property unable to do a double storey extension as a couple of the neighbours have done So the front bedrooms are a large decent sized room and one...

Hi all, I've just bought a house and I've noticed a couple of issues with the flat-roof extension. It seems like there is quite a fair bit of damp that has occurred in the corners of the kitchen extension. The lead-flashing looks a little suspicious, and there's no coping stone either. There...
