    Any reason why you didn’t use reinforced mesh before you poured concrete in? Been a brickie for over 25 yrs, every extension i’ve build always made sure i had steel bars and lifted it up on half bricks and then poured concrete over it. At times i even drilled bars into an existing house footings and left them sticking out so when i poured concrete i always thought it bonds better. Makes me wonder Was i doing it wrong all them years? 😂

    It depends on the requirements of building regulations - the weight & design of the intended structure, materials, type of soil, history of earthshifts etc. In this case the foundations for the extension were actually deeper than the foundations for the house - built back in the 1950's with much fewer regulations.

    BC has advised the firm sandy soil that is typical for my street a strip foundation at 900mm depth would be adequate for 2 story. We are planning a rear infill extension. I've done a trial excavation to 1.2m next the exisiting outrigger. I think I've hit hit the foundation. It wasnt possible to dig deeper with the tools I had and the time. Would it be normally required to dig to the same depth and "join" the new foundations to the old? Can you have foundations at different levels? Brilliant little series.

    In the UK, a Building Regulation application is valid for three years from the date of deposit. If you have started the works within the three years, there is no time limit to finish. However the onus is on the owner to ensure regular visits to check progress.

    It all depends on the earth, weight of construction, existing building & footings... BUT, 10cm doesn't sound like enough! Building regulations will specify the correct depth for the construction, so you'll need to consult building regs to ensure these are sufficient.

    It's more to do with the make-up of the ground, and the solidity of it - the UK doesn't have as much ground movement as, for example, the US or Asia, so steel rebar for small structures isn't always necessary. Large structures / houses, absolutely, but small > medium extensions, not so much.
