Glenmore Park Home Extensions & Additions
A home extension in Glenmore Park reads the estate's age — the 1990s-2000s brick is entering extension territory as families outgrow it, while the newer premium stock mostly gets the honest not-yet.
The 450 to 700m² blocks hold rear wings and ground-floor suites, the clay junctions are engineered, and the master-planned amenity keeps the finished homes in demand.
At the $1.0M to $1.6M range, the right wing beats the friction of upsizing within the Penrith corridor.

The estate ages into it
Glenmore Park's earlier brick is hitting the point where families outgrow the original plan — and the rear wing or suite serves exactly that.
The newer premium homes get the honest not-yet more often than not.
Clay junctions engineered
The reactive ground moves seasonally, so new footings are engineered to move with the originals at the junction.
That footing engineering is costed into the scope up front.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Glenmore Park homes from the 1990s–2010s brick + premium contemporary were built to different standards — we open walls, check footings, verify load paths. The existing house has to carry the new work.
⏱Design follows the existing roof. A bad extension looks like a bolt-on; a good one reads as original. Matched brickwork or contrasting render (whichever the architecture calls for), tied-in roofline, continuous flooring where it should be continuous.
⏱Construction happens while you live in the house. That means weatherproofing every night, staging the works so kitchens and bathrooms don't disappear on the same week, and keeping the site clean of debris that doesn't belong in a family home.
⏱Finish is seamless. Paint match, floor match, roofline match, brick match where possible. The only way to tell the extension is new is the date on the plans.
⏱Quality Promise
We extend Glenmore Park homes with a structural engineer on every job. Second storey, rear addition, multi-room — engineered and priced upfront.
