Important
Advertised base prices and package prices rarely include realistic site costs. Always request a site-specific quote based on your actual lot before signing a building contract. Contact the Bingara Gorge land sales office for current land pricing and availability.
Before You Buy Land
Soil Classification
Before finalising your build contract, arrange a geotechnical soil test for your specific lot. Reactive clay soils common in Australian growth corridors can require reinforced raft slabs or waffle pod slabs, which affect site costs.
Site Costs & Slope
Site costs vary by lot. Factors include soil class, slope, retaining wall requirements, stormwater connections and developer covenant requirements. Always request a site-specific site cost estimate before signing.
Developer Design Guidelines
Most master-planned estates including Bingara Gorge have design covenants covering facade materials, fencing, driveway finishes and landscaping. Check the developer's design guidelines before finalising your home design.
Wollondilly Shire Council Requirements
Building approval in Wollondilly Shire Council may involve additional overlays or requirements. Your builder should handle council submissions, but it's important to understand any local conditions that could affect your build timeline or budget.

Builder Red Flags
Watch For
Lots of Provisional Sums
Multiple PS or PC items in the contract are budget gaps you'll pay to fill — each one a potential cost blowout.
Site Costs Not Explained
If a builder won't break down site costs for your specific lot, expect a large variation after you sign.
No Detailed Inclusions List
If you can't get a full written inclusions list before signing, you don't know what you're actually paying for.
Upgrade Pricing Not Provided
If upgrade costs aren't documented upfront, you'll be choosing blind — and paying retail rates later.
“We’ll Work That Out Later”
Any builder who deflects important questions with this phrase is avoiding a commitment — walk away.
Soil Classification Ignored
If a builder won't discuss soil class or slab type before contract, they're not pricing your slab realistically.
Engineering Not Discussed
No mention of engineering requirements or retaining walls means those costs will surface as variations.
Unrealistically Cheap Base Price
A price significantly below competitors usually means essential items are excluded or will be charged later.
