Drafting services in Sydney (Drafting in Sydney) tells you: the estimate cost of construction work!
When it comes to doing a home project, every dollar counts. Especially with the market nowadays, it just gets harder and harder. The property market has been booming significantly and that doing extra work on an existing home may be the only way to go for many. Either a granny flat, first floor additions or building an extensions are a few options to be considered.
So when it comes to design and construction, how much does it really cost?
Before we start stressing you out with big numbers, let us break it down.
Home Project = Design & Approval + Construction & Project Management
Always set a budget for yourself. Don't ask the builder how much things are without knowing what you can afford.
How to work out how much to spend on a home design project?
When it comes to building or extending your new home, first work out the level of finishes you wish to use. Whether it will be a fancy home or a standard style will help indicate the amount that you will spend. Here’s some calculation you can use as guideline:
Range |
Cost per m² rate (exclude GST) |
Finishes/material example |
Basic |
Approx. $2000/m² |
Blue board, fibro board, colorbond roof, laminate joinery, standard carpet |
Standard |
Approx. $2500/m² |
Brick veneer, colorbond roof, laminate joinery, standard laminate flooring |
Luxury |
Approx. $3000/m² |
Double Brick, roof tiles, polyurethane joinery, timber flooring or engineering board flooring |
*Cost are estimate only and subject to the complexity of the design and final selection of material and finishes.
For example:
If you are planning to extend your home with a total of 80m² with a standard range of materials. You will be looking at 80m² x $2500/m² = $200,000 dollars (exc. GST).
What percentage does the Design and Approval part worth?
Generally, the design and approval stages ranges from 3% (New houses) and could go up to 6% (extensions and additions of complicated dwellings) of the total construction cost.
For Example:
With a total budget of $300,000 for an extension project,
5% of the cost goes to the Design and Approval Stage; $15000
