There is so much hype around home improvement, in part fuelled by shows like The Block, House Rules, Selling House Australia, Grand Designs Australia and of course, 9Life, which features home improvement shows from around the world.

There is, however, one key aspect missing from the majority of these shows and it’s the most important of all – a realistic cost! On a TV show, costs are reduced through sponsorship deals and discount agreements and budgeting doesn’t make for the most riveting of television, so it’s never discussed in great detail.

This phenomenon means many are unaware of the full cost of a home extension or renovation. The simple fact is that, unlike new builds, there is no simple m2 rate for this type of construction as there are too many differing factors. From the age of the house and type of construction to the size, scale, inclusions, exclusions and planning requirements, no two projects will ever cost the same

So how much does a house extension cost? In order to assist our clients, we’ve complied all the data from our previous jobs and experience and collated this into a rough price guide for common types of projects, including ground floor and second-storey extensions. It includes all the planning, approvals, complete construction, fixtures and fittings and painting. It doesn’t include floor coverings (carpets, floating floorboards etc) and window furnishings (curtain and blinds).
