Great excellant link thankls for info. For emgergancy escape they specify: 'however it should be noted to produce the required opening area a minimum 750mm x 450mm opening must be provided' so a 980x780 should be fine here..... Ventalation: Room size is 6.32m2 so 1/20th is...

About to fit a top hung Velux type roof window and wanted to know the minimum size the window can be but still conform to building regs. The window will be the only window in the bedroom of a dormer bungalow on the first floor and so will be the sole means of escape in a fire etc. I'm hoping...

The lintel only seems to catch about 1/3 of the outer brick leaving 2/3 exposed. At first i thought there was no lintel!! have you ever seen this? I'm ssuming your can just cement the piers to the existing brickwork !?!

becuase window is 3m wide.

With regards the original ceiling joists that are staying in place, ceiling hangers have been removed so would these ceiling joists need to be secured to the new floor joists? The ceiling joists are 3x2 and span around 3.2m??

Lintels will be staying in and window will be no wider than original. Brick pillars will be around 2 bricks wide.....

Thanks for your quick reply. Thats sorts the bedroom window out. Can you advise on these other two situations: 1. 1x large Lounge oblong window we want to split into 3 smaller windows again with brick pillar divides but depth of window increased so it is from floor to ceiling in height? 2...

planning I mean. BR would be involved as it's a window.

Are you permitted to divide one large bedroom window into two smaller windows with a brick pillar between the two?

Great view! It's a hell of a lintel. OK 300cm!

I'm in the process of planning to change some of the windows in my home. I understand we need building regs but if some of the windows will not be the same size as the original will planning need to be involved? Heres a rough idea of what we are changing: 1. Current Lounge window 3000cm x...

I was thinking along those line too. My main concern was getting the hanger at the right height, ie not touching the top of my downstairs ceiling and the same height as my other joists. So I think the timber hangers may be better suited.....

Which in your opinion are easier to install? The block to the right and left is cinder block would this have any influence?

Thankyou all for your help and advice, very much appreciated.

Thanks again. Would your suggrstion be inline with the building regs? If not, what do they specify......

Thanks tony. Any suggestions regards insulation of the roof in pic one?

OK great thanks tony, so the left Pic looks fairly straight forward with timber screwed to the block with 4” screws and hangers for the joists. The other side I have attached a diagram of what I think is what your saying???? and ensuring the timber is a good 2” from the chimney stack….. how...

they will be 3.2m span. they will be 175mm x 50mm joists. Its getting the joists stuck to the wall is my main concern......

Have removed a large wardrobe/stud partition underneath a supported purlin in my bedroom to open up the room into the eaves on the 1st floor of my dormer bungalow, and gain around 1.5m of floor space either side. I now need to add floor joists as there are currently only ceiling joists where the...

We have just removed a stud partitionin our dormer bngalow to open up our bedroom towards the leaves of the house, this means that part of our ceiling will now be the roof of the house. I want to insulate this to keep online with building regs but the rafters are only about 3 to 4 inches in...
