I'm being particular as my deck is 1m high, spans over a sewer and I need to satisfy a building control officer. I've gone for some Wickes face-fixing multi-truss hangers. Pricey though. Speaking to a couple of builders I know, they would just screw the thing together as long as the deck was...

Any recommendations for what joist hangers to use for a standard deck made out of 6x2? 'Jiffy' type ones are cheap but won't leave a flush finish for the deck boards as they strap over the top. The face fix ones are either 'mini' and too shallow or seem a bit heavy duty and really expensive...

I've thought of a new way to run this into an existing 110mm trap/gulley so this should be fine. Putting in a new 110mm drain would've been even more of a problem than an elephant-sized soakaway. How come a 40mm trap can cope with the huge flow of a bath emptying but can't cope with runoff...

Hi, I've recently had an extension built and the BCO wants the guttering to run into the combined sewer with a trap. A soakaway isn't suitable as next door downhill is a big stone barn with poor footings, poor soil and is very close to my house. It will be a huge faff to run downpipe to...

Hi, I'm building a raised deck that goes over a sewer. I have planning permission and permission from the water board to access the sewer inspection chamber (putting a hatch in the decking). I am supporting the deck at one side from the house wall. Can I just support the other side? Tricky...

Hi, Can anyone recommend a uPVC or aluminium conservatory supplier/manufacturer that provides structural calcs? I've seen a couple but I wonder if anyone had any other names. its only a tiny project but I've been around the houses and I am going to need structural calcs for my...

Hi, The conservatory I'm planning on building is 900mm above ground level and according to the BCO, this means it is 'controllable' and they want to see full calcs to show structural integrity. (Conservatory is at internal ground floor level but because of sloping site, its is 900mm above...

http://www.planningportal.gov.uk/permission/commonprojects/conservatories/ Building regulations will generally apply if you want to build an extension to your home. However, conservatories are normally exempt from building regulations when: They are built at ground level and are less...

Rang the Building Control Officer today who said my build is 'controlled' by them as it wasn't clear that the new conservatory was outside the existing thermal envelope of house, plus the floor is 900mm above ground level at the back of the house due to a sloping site. Coupled with it being over...

Thanks for getting back to me, and quickly. Access to the conservatory will be a new door where an external window currently is. Taking window out and cutting out the wall below the window and using existing lintel. They said it had to be full plans as I'm building over the shared sewer. I've...

Hi, I'm wanting to build a 2 x 5 metre small conservatory that covers a manhole/inspection chamber for a shared sewer. The water company has given me written permission to build over the existing manhole and build a new inspection chamber instead, however I'm having problem with local...
