building control

I'm planning a knock through between my kitchen and dining room and need beam/RSJ calculation (and drawings?!) For building control, but the local structural engineer is "unable to assist in the small project" as they are "too busy". Has anyone used an online Structural Engineer? One I was...

Hi, We’re part way though an extension and are doing some bits ourselves. The builder did the construction, but we’re doing the roof insulation and the boarding. We’ve used 10cm kingspan between the rafters, and will then cover the whole thing in 2.5cm Kingspan, which is what building control...

I am opening up a load bearing wall between kitchen and lounge and I am also installing an additional WC in a storage room (next to bathroom). I am not quiet sure how building notice works so would appreciate some pointer. So far the questions I have are: 1: Do I need to submit 2 building...

Hi, I am hoping for some advice. My builder has completed a loft and the building inspector has said the insulation is not sufficient as it has a u value of 0.22 and not 0.18. I have spoken to my builder and he says we could argue on the basis of height that additional insulation would not be...

I've just bought a house with a very usable cellar - it's been insulated and has heat and light and fully decorated - all with planning permission. We bought it as a non-habitable room for storage as it didn't meet building control. I've looked at the regulations and I'm not sure why it hasn't...

Hi, Hopefully someone can help me ...... I am currently selling my late father's property, one which he built in 1971, this is a 5 bedroom house with a loft conversion (2 bedrooms) constructed in 1982. Due to the fact there were no records from BC during the local search by solicitor, the...

I'd like to install an external mains socket on the outside wall of my house in the back garden. This would be a weatherproof IP66 13A socket with RCD. It would be connected as a spur on my ring main with a fused spur switch on the inside wall. Would this need building regulations please? Does...

I have just installed the following two beams for my loft conversion. 5.1m 203x203x46kg on 100x150x500mm pad stones. Unfortunately these are sticking through the roof slope. I have been told by an architect these can be cut at 45 degrees halfway up the beam without compromising the structural...

Hi all, We are newbies, planning to build our first rear extension. Currently we look to switch from expensive-and-not-very-responsive architects with whom we have started to work on options for our rear extension, to some more affordable architectural design bureaus. One option is to take the...

Hi. I have new upvc windows & doors to fit in my new extension with 150mm deep external sills. The BCO has said he wants them fitted in the middle of insulated cavity closer ( screwed into thin plastic?!! ). Obviously if I fit them there the external sill will not over hang and be sitting on the...

My local building control are happy for me to install my own woodburning stove, and they'll sign it off within their fee - provided it meets regs. So, I've designed it, but will it pass? Here's my design, any thoughts, constructive criticism or total freakouts from knowledgable DIY'ers or pros...

Hi All I hope someone here can guide me on the below. I have had built decking in my back garden. My garden itself is sloping. As a result of the slope the deck from the back of my house is below 30cm, in height, from the ground whilst the front of the deck is approx 50cm, in height, above the...

I'm renovating my house, part of which involves knocking through what used to be an external wall, into an existing extension. I've got structural calcs for the works to re-support the wall and am aware that it will need to be inspected by a BCO, but this has led me to check whether the...

I've started a massive upgrade on my house following finding out I had a cowboy builder who done my loft did everything wrong as he didn't fire proof and insulate the loft which is technically dangerous. Which the building control failed to enforce the regulations at the time and after forcing...

2.2m x 4m shed. I've built a timber shed in my garden that's within a metre of the house and boundary, I've been informed by the council that I'll need a building warrant. They've stated that unless it's a metre away from the house and the boundary then I need a warrant. Surely this means...

I am building a lift from ground to first floor and hanging it off the side wall of the house. The lift platform is 1x1.2m and the shaft is to be constructed using SIPs. The top of the shaft will be in line with the eaves. Do I need either planning or building regs approval for this - I can't...

Hello all, I have tried searching for this everywhere but cant find the answer. I wanted to know if, according to building regs, the cooker hood ducting has to go out of the nearest external wall? I plan on having an extractor hood with an external motor so instead of it coming out of the...

Hi all, wondered if anyone can help. I can't seem to find definitive answers online and am dubious about contacting building control and flagging them as to my intentions unnecessarily. We've had a new 5m x 3m log cabin installed in our rear garden and planning to hook up a toilet, hand basin...

Oil tank located currently in an outhouse needs to be replaced and doesn't meet current regulations anyway. Not many options to put it anywhere else as the yard between the outhouse and house is pretty small. Has anyone installed an integral 60 minute fire-checked bunded tank (like the tuffa...

Hi there, As per the title I have granted PP to build above my flat roof single storey kitchen. I understand that a steel beam will need to be inserted into the load bearing walls. How does this work in terms of building control, structural plans etc. Will the inspector's need to see...
