Our process

Step 1:

Initial meeting

During our first meeting, our goal is to listen carefully so we can visualise your house extension as clearly as you can.

Step 2:

Initial design and pricing

Using our extensive design and construction expertise, we’ll create a concept and give you an estimated cost.

Step 3:

Preliminary Planning Agreement

Once you’re happy with the design, we’ll ask you to sign a PPA and pay a nominal fee to progress to the contact stage. We’ll later deduct this from the contract total.

Step 4:

Approval process

We work with local governments every day, so we’ll handle the entire council approval process, including full work drawings.

Step 5:

Materials and final cost

We’ll work with you to choose the right materials and finishes for your home. Once you’re happy, we’ll present you with a fixed final price.

Step 6:

The contract

With your designs, materials, and approvals finalised, we’ll sit down to sign the building contract and answer any questions you have along the way.

Step 7:

Confirmation and timeframe

Together, we’ll finalise the start date and set realistic building timeframes. That way, we can do a great job, not a rushed one.

Step 8:


During construction, you can continue to live in your home with minimal disruption, thanks to our in-situ method.

Step 9:

Your dream come true

When construction is complete, your dream will be a reality. You’ll be able to enjoy the many advantages of a house extension in Perth.

Green-Shore were fantastic, extending out and up our 1920s home. Clint is professional, flexible and got our job done a few weeks ahead of schedule to a very high level of workmanship. His staff and all sub-contractors on site are at the top of their game. Thanks guys.

Ray & Tania

I used Green-Shore to design and build my ground floor extension. A professional and conscientious service from start to finish. The project was managed effectively and completed within a short timeframe by a great team. I would recommend this business.

Tom Dobson

Green-shore finished our renovation 3 months ago – single storey extension including kitchen / living / dining, butlers pantry plus master bedroom and ensuite, to a 100 year old brick & tile house in Vic Park.
Very happy with the Greenshore experience.
