    Hello,

    Iam looking to build a two storey house in Ryde area and the land has a 4m drop from front to rear backyard fence.

    Have anyone built with Ryde council before?

    Could someone recommend builder who will build on sloping block?

    Would anyone share there experience and costs when building on a sloping block?

    What important design elements should i specifically look out for that can be detrimental to the completed house if i don't get it right at the drawing stage?

    Love to hear your comments and ideas.

    Be one with the land :) get the balance of cut/fill and excavating and retaining walls. Design needs to work with the land

    Split levels work well

    My PPOR is a 2.5 storey house built into a sloping block. There is an upstairs/ downstairs and an in between level which extends out the back. I think it's a great design.

    it looks great!!! our slope is actually steeper than yours.

    may i ask did you go through CDC or council?

    was it significantly more expensive?

    what foundation did the builder use? screw or bored piles?

    The design that I had on a block had slabs at two different levels - combination of slab on ground for garage with thickened edge beams and strip footings with slab on fill. There were also a couple of 300 dia bored piers.

    Alternatively, there are several other options for adjustable steel piers if you want timber flooring

    Our backyard is cut in about 1m from the ground above - has a retaining wall. Then within the backyard there are stairs about 1.5 high with a retaining wall which allows both the middle and lower levels access to the backyard. Our front yard has a gentle slope. I'm not sure exactly but I'd say our block has a 3-4m drop back to front. Everything is terraced though, so it doesn't feel like it.

    We bought it new, but was already being built. We didn't go through the approval process.

    Pic is from the middle level looking out to backyard. You can see the retaining wall at the back. My land has been cut down about a meter to level the backyard.

    You can't see in the pic, but there are stairs on the left near the house that go down about 1.5m and allows access to the backyard for the
    The second pic is taken from the stairs . Sorry for the bad pic, it's all I had.

    The way they built in the good ole days on stumps with bearers and joists.

    Can be cheaper on slope as you don't need to cut into the ground till flat. Can just stick out of the ground at one end or step down.

    i actually spoke to a builder and was advised that the old days stumps and bearers were no good since the piles does not go deep enough into the ground. So if the stumps move then you will get major structural cracks to the house.
