Well balancing out material and costs labour costs is one thing but 2 story is quite a bit cheaper to build ; far less foundation and roofing area. It also simplifies the plumbing and of course is far more energy effective as downstairs heating will also contribute to upstairs heating. PROs can develop on this. And as Curt points out, modular is a very fast and cost effective solution which can allow you to put your pennies into better quality. Be very careful to select a known and competent professional if you go this way though, i don't know about NZ but europe abounds with cowboys ; low costers are to be strictly avoided.

Hey guys - im wanting to renovate my small bathroom, its around 56 sqft, replacement of standard shower over bath, single vanity and toilet, tile floor and tiled wall just within shower/bath alcove. No changes to plumbing location. Have a quote for $9500 just for labour and rough materials (I have purchased all fixtures, finishings etc for a total of 3k), is that labour quote reasonable? Nothing is tricky, ie; standard stacked tile pattern etc. Im in Oakland, CA, so I imagine that effects the price. Any advice would be massivly appreciated! Thanks!

We asked a similar question when we bought our piece of bare land. We were advised that building a simple shape would reduce costs... so we've built a t shape. Single story is almost always cheaper. We have a builder who is happy to let us do a lot of work with him. We also choose to live on site, which saves us a lot in fuel. The kids and I clean up the building site most days. We've been able to separate the rubbish out between actual rubbish and recyclable material. As for cladding, we were going to do a mix of corrugated iron with plywood board and batten. But given some of the additional hassles, I don't think there's much in it cost wise. However, in saying all that, we chose to invest in long term benefits, so our house is exactly what we want and should be cheap to run. We were hoping to build for $1800 /sq m but we're still coming out at about the $2000 mark.

Debating replacing a 10 degree roof with a 45 degree roof to optomise going off the grid. Building is 9 metres wide [includes 500 eaves] by 12 metres long. We would increase the length to 16 metres to cover an existing deck with ancient corrugated plastic roof. Question is cost. We have the room to build the roof on site and crane into place otherwise make it offsite. We would need to put a couple of windows in length to give character. We would use dark grey ribbed coloursteel ideally and reclad south and west walls with the same material. Does anyone out there have an opinion?
