HI Emily Carpeting bedrooms is only dictated by your budget. The only variable is the price of the carpet, all other costs (installation, smoothedge, underlay) will be the same no matter what you choose. When you say remove wooden floors....do you know what is already installed? If you are only wanting to take the wood from the bedrooms but leave it in hallways etc, then the cost to remove wood planks (laminate?) may be around $20 per m2... A lot depends on how the timber was installed, so I think it's best to get in a professional and get a free quote. Good luck.

10% is actually the rule of thumb number that I have heard used for years. Of that 10%, about 60% typically goes to construction docs and the other 40 goes to the earlier phases of the job. Pre-design, if any, is often done hourly. None of this is set in stone anywhere and it will vary depending on the designer's experience and overhead, the complexity and size of the job, etc. There is certainly nothing alarming or unreasonable about asking 10%, and in design, as in most things, you generally get what you pay for.

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.

I didn't see this either , and how long is a piece of string ? Wellington ( a bit like parts of Queenstown ) is known for steep slopes and high winds , so the actual design will affect things a lot -- my sister once 'conned' me into moving her to Wellington when she got a Government job . We loaded one of my small trucks and drove several hours , when we got to her new place on the side of Mt Victoria with lovely harbour views , it seems she had forgotten to mention that the new house was the one up there -- yes , a 1920's build 130 steps up from the street . Hard enough moving a glass fronted china cabinet and solid Kauri 1880s dining table -- imagine carting every bit of timber , tile , window , kitchen appliance up there !
