I’m attempting to replace a mixer tap cartridge, but it has disintegrated during removal. I’m left with the plastic outer body stuck in the tap. Any ideas how I might be able to remove this? I’m not sure if I’m supposed to turn it, or pull it. Neither seems to be working. Thank you!

We’re thinking of having the door to our extension in the blue shaded area - which passes through the existing SVP. How easy is it to rotate the exit pipes for the two toilets to go the other direction to join to a relocated SVP (proposed pipes shown in red). Could this work all be done...

We have water coming into the room below the roof on the sides of the room when it rains. I'm unable to climb onto the roof to take a closer look as it is too high and I don't have access from below. I've taken a look at the roof from the window above and the flashing looks a bit suspicious -...

We have planned an unventilated pitched root which at the top will join to a flat warm roof. For the unventilated pitched roof (as in the detail attached), would it be a good idea to add in some tile vents just to make sure there is a bit of extra air flow in there? Thank you

Hello. When I look at construction details for warm flat roofs I see the VCL is placed above the joists. However for a warm pitched roof the VCL is placed below the rafters. For example see the attached image from...

Our design company is doing building regs full plans drawings. Once approved by BC how closely to these plans does the builder need to stick? Can materials or the build be altered at build time (presumably with approval of the approved inspector) - or is this something that the inspectors would...

Hello, if the party wall process has been started before planning permission has been granted, and then planning permission is refused, is there an easy mechanism to end the party wall process? The party wall act doesn’t seem to have much on cancellation. Then if following refusal a new...

Hello, We’re figuring out the design for our crown roof - something like the attached image, where we have a flat part on the top (with appropriate fall to stop water pooling), and then it would be pitched on three sides. Would this kind of roof be better as a cold roof or warm roof? I...

Hi, Our extension width and length is not divisible by an exact number of bricks (taking into account a standard mortar width of 10mm). This is for an extension with planning permission - not permitted development. What might be the best approach? - create the walls slightly under the planned...

Hello, I’m trying to design a crown roof for our rear extension with two of the sides at 270cm (to reduce light impact for the neighbour) and 300cm at the other two side (to allow us to have higher kitchen units). This creates the problem of what to do at the transition between the heights. I’m...

Hello, we are planning a rear extension which will add an new UFH system, one extra radiator, and an extra towel rail. Currently we have a 10 year old Worcester Bosch 25si combi boiler which is doing alright. It has recently been serviced and the gas engineer said it is looking good...

With the 2023 building regulations changes it looks like the external wall width (from exterior brick to finished plastered internal wall) for a new extension would be: 102.5mm - exterior bricks 150mm - cavity for standard insulation (unless using some higher performance / more expensive...

Hello, hoping I can get some feedback on a drainage layout I'm trying to do for our extension. This is an update on an earlier design I posted - I've now removed the internal manhole and it is located outside instead :) We have a private combined drainage system that heads over to our...

Hi, I’m having difficulty finding an answer to what seems a simple question. What is a typical depth for a warm vs cold roof in a rear extension? i.e the measurement from the underside of the ceiling to the top of the roof. Thank you!

Hi, I'm trying to self plan a rear extension to our semi-detached house, and hoping someone could give some feedback on my drainage plan. Currently the rain water pipe (RWP), and soil vent pipe (SVP) connect to a manhole at the rear of the property. This is a private drain, that then runs into...

Hi, we currently have a vertical soil vent pipe. It is in the way of where we would like to build a rear extension. I’m hoping someone could offer some guidance here as without moving this pipe we’d be unable to open up the rear of the house. Is it likely to be acceptable to remove the bottom...

We had our verge mortar replaced one month ago. The roofer took off all the tiles, replaced the under cloak, and then put new mortar down and replaced the tiles. Would anyone have any ideas of what went wrong? The mortar has come away from the under cloak along its full length, and a few...

I'm thinking of doing some work on the gable wall of our house and would need scaffolding installed. Set back ~30cm (is that gap allowed?), from the part of the wall to be worked on. This would be to allow some repairs to cracks in the render of the wall, some repainting, and then installation...

Hi all, We are getting penetrating rain coming in through our gable wall. The gable is made of block work added for a hip to gable loft extension, with a very thin concrete render over the top. There is some cracking visible as seen in the photo. We are thinking of the following solution: 1...

Hello, Hoping someone might be able to help with our drain connection idea. We currently have a private drain that passes behind our house over to our neighbours garden that is marked on the Thames Water plans. From our neighbours garden it then goes into the main sewer. We'd like to do a rear...
