A custom home in North Kellyville 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.
Building Custom Homes in North Kellyville
A custom home in North Kellyville is a build-on-your-lot in a 2010s master-planned new-release suburb. The streets run contemporary brick and rendered homes on 350 to 650m2 R2 lots, adjacent to the Box Hill growth corridor, and at a $1.4M to $1.9M market a designed home lets you step past the volume-builder template. Strong young-family demand anchors the area.
The lots range from compact to mid-sized, so a double-storey design captures the floor area a family needs while keeping a usable yard. This is Wianamatta Shale, so footings get stable, predictable bearing and a slab off geotech is routine. On a new registered lot the pathway is usually clean, with estate design controls the main thing to answer and no demolition or heritage to manage.
What I would check first on your North Kellyville lot: the estate design controls, the double-storey design for the block, and the slab off geotech. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your lot and brief and we will draw it.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

How It Works
From First Call to Final Key
We start with a site visit or showroom meeting to talk through what you want to build on your North Kellyville block. We'll review The Hills Shire Council's planning controls for 350–650m² lots with R2 Low zoning and give you a straight answer on budget and feasibility.
⏱Design starts with site analysis — sun path, prevailing breeze, neighbour overlooking, slope, view lines from each likely living area. The plan is drawn to that, not dropped onto the block.
⏱Working drawings, structural engineering (Class M soil design), BASIX certification, geotechnical report, stormwater plan and all certification documentation prepared..
⏱Most custom homes in North Kellyville qualify for CDC with a 10–15 business day turnaround. If DA is required through The Hills Shire Council, we manage the full submission and respond to any requests for information.
⏱Construction is run from a programme, not made up week to week. Trade sequencing is locked in advance so the slab cures into a waiting frame and the frame waits for nothing.
⏱Walk through your finished home, collect keys, and move in. OC issued, defect-free inspection completed, 6-year structural warranty, and full maintenance guide provided.
