Hi Ferdinand - many thanks for the comments. The detail of the gutter lining finishing definitely needs further development - as you suggest I was planning to mortar into the brick joint. You raise a very good point about access and maintenance, there are two existing windows roughly above the gutters at either end of the proposed roof. These would be ok for cleaning the gutters, although if repairs were required it would obviously be preferable for the roof to be able to support someone. The proposed roof has two large skylights so if the additional weight of a person has to be factored in then maybe I need to run it past a structural engineer before taking it any further. Thanks again, JM

Thank for the tip - I'll have a look into GRP - always thought EPDM may be more likely to leak at junctions so GRP could be a good call.

Many thanks for your helpful replies. I've started the process with Thames Water as suggested and it seems to be going ok! Thanks again! JM

Hi all, I'm designing an extension to the rear of my house and was planning a very shallow pitched roof with a couple of roof lights. Having struggled to find the exact detail online I've drawn up the detail below indicating the roof junction, skylight & hidden gutter. I have little experience in construction and would appreciate any comments/potential problem areas. Many thanks, JM

Hi, We're planning to build a ground floor extension to our 1960/70s terraced house, which is semi-detached at the end of the row.We have a manhole cover to the side of where we plan to build the extension and although we don't plan to build over it, we were wondering if anyone could give advice on whether the sewer pipe is public or only serves our house. Photos below. If anyone could advise the best strategy for dealing with sewers/drainage, so as not to risk any issues when creating the foundations of the new extension it would be greatly appreciated. Many thanks, JM. 1. This is the man cover removed. To the top left is the end of our house, the extension would continue along this line of brickwork. 2.Close up of sewer pipes. 3.Sketch showing layout of sewer and house.
