Thanks for replying Woody. No load from door as it’s ground supported. Just load from near flat roof. Can I assume dead load of 0.75kN? Do I need to add in additional load if the joists are sitting on the lintel? Hoping to avoid paying for SE to do calculations since building control is not...

Hello, I want to put in 3m bifold doors in a garden room. The construction is block and render with flat roof. Currently trying to work out what type of lintel is best for the bifold doors. I guess there are 3 options: 1) RSJ (is 127x 76 x13 sufficient?) 2) Flitch beam (8x2 joists with 8/10mm...

The glazed door was required if we build an side extension. My friend wanted to put a door here to have an own entrance instead using the shared porch.

Yes, in the approved plans for the side extension, it was stepped back by 1m. I think this distance was requested by the council. I would have suggested to build the side extension without integrating with the main house if the council was ok with not having a glazed door. The council said she...

Thanks for your suggestions. The gate won’t be 2.4m high, just the gate posts and the boundary wall. From reading other posts on this site, the ground level for the boundary wall is taken from the neighbour side so as long as the wall is no higher than 2m on their side then we should be ok...

Looking for some advice on planning permission and building regulations for a covered walkway/lean to for a friend. She applied for planning permission for a side return extension with a door at the front of the house which was approved. I think the council said the door had to be glazed as...

Thank you for everyone’s advice and comments. I have learnt a lot and understand some things better. Now I am not so clueless about kW, Amps, diversity, etc. This is a great forum.

Says 40A on the MCB

Having read a lot of posts on this forum 2 nights ago, I did get the impression that he knows his stuff. If it was up to me, I would follow his advice without question but it’s not..someone else need to sign off the work. Can you imagine me arguing with the electrician… “I read on the...

Glad to hear it. I will tell the electrician your recommendation.

Thanks for your reply. Isn’t it best to have hob on its own circuit? This seems to be the common recommendation that I read about on the internet. Along with future proofing using 6mm cable instead of 4mm. I don’t think we can connect the oven to hob circuit as the hob is on island and I guess...

I will ask him when he is back from holiday. I assume the hob is separate to oven because it has a separate mcb on consumer unit. If I turn off the fuse for oven, the 3 appliances is also turned off.

The is some sort of plastic cover with wires on the wall where the oven will go. I know it needs to be hard wired in. I think we will need to run a new 6mm cable and create new circuit for just the oven.

Hob is 6.4kw. Only the 3 appliances and oven on the new ring circuit. The manufacturer’s manual says 4mm so I guess that need to be the minimum cable size?
