Custom Home Annangrove — Design, Approval & Build Under One Contract
Full design-and-construct service in Annangrove 2156: site assessment, architectural design, The Hills Shire Council approvals, engineering, construction and handover. One builder, one price.
Quick Answer
A custom home in Annangrove costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, The Hills Shire Council approvals and fixed-price construction.
Custom Homes Designed for Annangrove
A custom home in Annangrove is an acreage build, and that changes everything about how it is approached. On 1 to 10ha RU2 holdings, the home is one element of a whole-of-site design that has to account for bushfire, on-site services and how the house sits in the landscape. Owners in the $3M to $8M-plus range are building the long-term family estate, not a project home on a slab.
The compliance stacks up. Bushfire overlays are significant, so an RFS assessment and BAL-rated construction apply, there is no reticulated sewer so a certified on-site AWTS system is designed in, and Hawkesbury Sandstone means excavation is priced by test dig. Siting the home for aspect, access and the equestrian or lifestyle use matters as much as the floor plan.
What I would check first on an Annangrove holding: the BAL rating and RFS path, the AWTS design, and where the home should sit on the land. Those drive the whole project.
We build these fixed-price, licence HBL 487805C. Start with a full site constraints review and we will run it.

How It Works
From First Call to Final Key
First meeting is about getting the brief right — number of bedrooms, lifestyle priorities, future-proofing, budget envelope, and what you'd hate to compromise on. We pair that with what your Annangrove block actually allows under R2 Low controls.
⏱Floor plan designed specifically for your Annangrove block — orientation, setbacks, views, slope, and how you actually live. 1–10ha (acreage) blocks allow generous layouts.
⏱We prepare everything needed for approval — engineering drawings sized for Class M ground conditions, BASIX certificate, geotech report, survey, and stormwater plan. All documentation handled in-house.
⏱Lodgement, RFI responses, condition negotiation, and CC issue — all managed in-house. The Hills Shire Council has typical processing windows we plan around so the build start date isn't a moving target.
⏱Construction runs 24–40 weeks depending on size and complexity. Your project manager provides weekly updates with photos and milestone tracking.
⏱Handover is a sign-off process, not a key drop. We walk every room with you, mark anything below standard, complete those items before settling, then issue OC, warranty, and documentation.
