Money-saving Tips on a Knockdown Rebuild 


The first money-saving tip is to carefully consider the materials you choose. Obviously, you want the design of your dreams, and you want high quality, but there will be places to splurge and places to scale back. 

Energy Efficiency 

You can save money in the long run by investing in energy-efficient materials, fixtures, and appliances in your rebuild. This may also qualify you for government incentives, which will deliver more savings. 

The House Plan 

The Achilles is a stunning design, but the Tyndall delivers four bedrooms and two bathrooms just the same. So, if lot space isn’t an issue, there’s no reason to build up when you can build out for cheaper. 

Cordeux and Hamilton designs offer five bedrooms, but if you don’t need the four bathrooms the Cordeux offers, the Hamilton delivers three, which is just as sweet. 

The Homebuilder 

Choose the right team to work with. The more experience they have the more efficient they will be, which is good for the cost of rebuilding a house.
