Our process

Step 1:

Initial meeting

During our first meeting, our goal is to listen carefully so we can visualise your second story 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 second storey extension in Perth.

View all testimonials

The BEST renovation & second storey addition builders in WA. Quentin, Clint and everyone of the people that work for them are amazingly talented, approachable and want more than anything for their clients to be happy customers. I totally recommend them.

Joanne Bastian

Green-Shore were fantastic, extending out and up our 1920’s 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 sire are at the top of their game. Thanks guys.

Ray & Tania

We have just completed a second storey addition to our 1910 built home with Green Shore. I wish there were more than 5 stars to give these guys. They are awesome! This is our third build and 2 of the 3 previous builds with different builders were a nightmare. With these guys we could relax and know that everything was extremely well organised and finished to a very high standard.
