Years ago, a developer came to me and told me he was selling land very cheap ($60,000-$70,000). However, the blocks required water tanks and treatment systems ($20,000). He wanted to product house and land packages for under $250,000. Even then, that was a tight budget. So we set to work to design the most cost-effective homes we could.
What we came up with were 3 bedroom home designs that looked really nice and were much cheaper than anything else selling at the time. The homes included:
* rectangular homes, no more than 7-7.5m wide;
* a low-pitched hip and gable roof with a patio awning attaching to the side;
* Hardiplank cladding;
* sliding windows throughout, with some double sliding glass doors.
Sounds a little boring? Well, painting the cladding light grey and adding white windows, gave the home a stunning look that suited every area from the beach to the bush.
For owner-builders, this was a very easy home to build.
Over time, we specced the design up a little and now it is the Cooroy design on our website range. Modifications of it continue to be a popular choice, and some owners have added a full wrap-around veranda, which looks amazing.
As you add larger spans, kick-outs in the design and a more complicated roofline, the costs start increasing quickly.
Top 3 Design Aspects that Will Add to the Cost Dramatically:
large open spaces, voids and raked ceilings
large windows, louvres, casement windows, stacker sliding doors and bi-folds.
