    My mum is looking to have a small orangery / extension on the rear of her 1970s bungalow. Currently the area she'd like it sited on is slabbed.

    Essentially it's going to be a single storey extension with roof lantern.

    What's the best build up?

    For the floor could she even lay EPS straight on the slabs, screed on top?

    Then timber frame or block on flat with EPS EWI built on the slab?

    In my head I was thinking of a a basic timber wall plate attached to the existing rear wall and a flat roof with appropriate timbers for an EPDM flat roof?

    The orangery will eventually house her kitchen.

    Input appreciated

    Build a proper extension WITH foundations!

    VictorianEco - I looked into this for our bungalow.

    The orangery would have been a steel frame job, basically a steel goal post arrangement out in the garden with suitable cross members to form support for the flat roof and roof lantern and attached to the bungalow wall resting on piers. There would have been concrete foundations with well insulated sub-floor, screed, dwarf walls and lots of DG windows. It never happened because my wife wanted a conservatory and guess who won!
