You'll notice that the portico has a pvc downpipe inside the pier and that's what the op was obviously trying to do with the garage down pipe. That section of the garage will also have downpipes from the second story feeding on to it. Personally I'd be doing the roof differently to the way it's drawn, but that's the cheapest way to do it and rainheads are the only option with the way it designed to be constructed.

It's just doesn't happen here in WA. It's drawn that way for a reason. Maybe over east you have more options to run downpipes internally but with double brick and suspended slabs it's a different kettle of fish.

Core drilling the existing slabs etc as you say would be a pain. The few double brick homes with concrete slabs I've worked on before have had a couple of internal stacks one for sewer and the other two for downpipes and if they are designed right at the start they can be hidden. It depends how much of an issue the owner has with downpipes at the front of a house and how keen the builder or his designer are to accomodate them I guess. Stewie Re: Downpipe in cavity? 16May 30, 2015 5:46 pm Hi stewie. Absolutely agree with the plumbing stacks. I think the days of running plumbing down the outside of buildings is long gone. It looks so ugly.

It's a garage pier that is structural. It's holding the lintel and formed concrete beam for the upper floor. Just about every double story house in WA has the identical set up. My house is exactly the same. Get a nice rain head and use round downpipes and they look fine. The house has not been built yet. We are at pre-start stage. Currently the drawing shows no cavity but can't the cavity be created just like how they did it to the garage wall on the left where a cavity downpipe is there as well?

Why do you have to drill the second story slab when there isn't a slab directly above it? The builder did notify me that the variation item is done but I have yet to get the details and the price of the variation. I will post it once I get it.

Stewie I am currently finalizing my pre-start and will post what the builder proposes. Re: Downpipe in cavity? 20May 31, 2015 1:52 am There is a slab above it. The second story slab runs right over to the zero lot garage wall as noted on the ground floor plan. If the house is only at pre start then it is achievable but they will have to make provision for it by having a penetration through the slab and a small stack in the front corner or running the cavity wall all the way through to the front of the garage. I would be interested in what they are going to charge you to do this.
