mandrake

hey everybody, we are building a side extension on our bungalow, we have ensuite and a separate bathroom, both toilets line up with each other on the plans, can we run the soil pipe under the suspended floor to start from one toilet then pick up the other and run it under our dining room and lounge in a straight line and come out the side wall into a chamber and away, i wasn't sure if you can run soil pipe like this has one of the things ive had little to do with in the past. any advice or help gratefully appreciated.

hey everybody, just joined, im renovating a 1950s hip roofed bungalow, im building an extension on the side of it and am going through regs and stuff, anyway the existing roof is cut with 100x30 rafters, 125x75 purlins, my question is can i use the same sizes for the roof extension, this is one of many questions to come, thanks for any help or advice i get though.
