Foundations Help and Advice Needed

[Mattyi26]

Hi All,

My first post on this forum which has given me plenty of information so far!

My Plan;

I currently have a 10 year old 2 bed terrace house and wish to add a conservatory to the rear. The first issue i have is approx 300mm from my boundarys is 2 small round inspection chambers one each side (one for kitchen waste and one for bathroom and downstairs toilet). The only service my property and these have a slight angle pointing towards the middle of my garden. My proposed conservatory size is 2750mm x 4000mm (almost the whole width of house bar 300mm each side)
The problem i have is the run is going the same direction as i would need to add foundations. I am not sure if i can lintal over these pipes to bear the weight as these are so close to my boundary at the house and i cant dig under my niebours garden for the concrete side obvously.

Could i use steel lintals fixed onto my house brickwork bridging the drainage pipes with the other end on a concrete base/pillar as there is plenty of room further away from house.

I can add pictures tomorrow to help explain situation if need be.

Thank for any help provided.

Matt

Photos and a sketch would help

Hi pal,

Not a completely relevant answer, but I recently built a conservatory using a Durabase system, a steel frame that has legs that sit on top of 300mm^3 concrete pads, thus removing the need for trench foundations.
I had a very simple area to work with so it was ideal. Worked out a little cheaper than having trenches dug and also with very little drying time you can build up very soon after. Less mess too. Good luck

.....and about a quarter of the quality.

Noseall are you talking from experience?

I like to over-engineer and my base was rock- solid. I'm not saying it's a better choice, but on my simple site, it provided a perfect base for full height panels. I didn't like the modular dwarf walls they do, so if you are referring to that, from afar Id agree with you.
But from a foundation POV, given my terraced home, it was far less messy and gave an excellent base. Noggins created for existing drain access, very very sturdy.
