Hello Everyone, I am progressing with some quotes for the foundations for my Potton home. I must admit, the prices have me a little daunted as they seem to be a lot MORE than I was told about 6 months ago. I am not suggesting I am getting "shafted" but I want to run it past you guys to see what you think. I am building a Potton Timber Frame and have been advised that Block and Beam would be the way to go ....easier and more friendly on the surroundings (i.e better received by planners) The house area from looking at the architects footprint and adding on roughly 50cm around (I just did this to be on the safe side for my working out ...I am not sure if it actually done) ..I am coming up with an area of 121.81 Sq Metres with a Perimeter of 49.82 Sq Metres. Now I have the first quote and it is over £23k, I know this company is trusted and has done many foundations for timber frames...But does this seem expensive? I have snipped the basics from the quote below ..so you can see what it entails ...hopefully someone on here will know what some of the specifics mean thanks
Can anyone remind where I can find the post discussing how many ducts to put in before pouring slab as I cannot find it. I have so far: Main electrical incoming supply Telecoms (Phone and Tv for exterior aerial) Power to garage Power to gates and possible camera/intercom (in separate duct) Exterior lights (may come from detached garage but I realise better control from house) Water Duct from plant room to kitchen island electric and water (internal duct) ASHP (water and power) Spare All these will basically come up in the plant room and some may never be used but better to have them in when we pour the slab. Any others that people have put in or wished they have put in or can point out the thread I cannot find.TIA
Thanks to the members of buildhub for the constructive advice and a good ground worker we have managed to get our foundations in. The archeological watching brief wasn't the problem we had feared and nothing was found to delay this first step of our build.
I've realized we have the available height to add an additional sheet of insulation under our 100mm ground floor slab. Originally I had planned on using 2 x 100mm EPS70 with the DPM underneath as stated by Jabfloor. If I add an additional 100mm sheet on the bottom would there be any issues using it as a blind and sandwiching the DPM above it but below the upper two sheets? Consensus seems to be EPS can get wet - but Jabloor to state DPM first then EPS hence the doubt... Also any additional issues going thicker with EPS70 rather than one of the denser variants? thanks
