A custom home in Penrith costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Penrith City Council approvals and fixed-price construction.
Custom Homes Designed for Penrith
Penrith's 450m² duplex minimum is the lowest in the region, but flip that fact around and it says something about custom homes too. This council backs residential building, and approvals here move with less friction than most of Sydney. The established streets hold 1960s to 1980s fibro and brick on 450 to 750m² blocks at $850K to $1.3M, ringed by Westfield, Nepean Hospital and the stadium, a full-service city, not a fringe suburb.
One overlay demands respect. The Hawkesbury-Nepean corridor brings flood planning controls on the western edge, so floor levels and siting get set by the mapping on affected blocks, checked in an afternoon, before you buy. The fibro streets are the classic pipeline. End-of-life house, land underneath doing the appreciating. Build new on it.
What I would check first on a Penrith block: any flood planning control on the western edge, the age of the existing house, and the zoning. Those set the plan.
We build these to last, fixed-price, licence HBL 487805C. We will run your address through the flood mapping first, then talk plans.
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.

A council that backs builders
Penrith's 450m² duplex minimum, the lowest in the region, says something useful: this council backs residential building, and approvals move with less friction than most of Sydney. The established streets hold 1960s to 1980s fibro and brick on 450 to 750m² blocks at $850K to $1.3M.
It is a full-service city, ringed by Westfield, Nepean Hospital and the stadium, not a fringe suburb. The fibro streets are the classic rebuild pipeline: end-of-life house, land underneath appreciating.
Flood mapping first on the western edge
One overlay demands respect. The Hawkesbury-Nepean corridor brings flood planning controls on the western edge, so floor levels and siting get set by the mapping on affected blocks.
It is checked in an afternoon, before you buy, so it is never a surprise. Send us the address and we will run it through the flood mapping first, then talk plans.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. 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 Penrith block actually allows under R2 controls. Walk away with a realistic shortlist of design directions. Floor plan designed specifically for your Penrith block — orientation, setbacks, views, slope, and how you actually live. 450–750m² typical (Cranebrook/Werrington/Cambridge Park/Kingswood/St Marys); 250–450m² master-planned (Jordan Springs/Caddens/Glenmore Park new release) blocks allow generous layouts. Multiple options, 3D renders, and finishes palette.
⏱The Penrith construction phase. Fixed price, programmed, supervised. 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. Penrith City Council has typical processing windows we plan around so the build start date isn't a moving target. You see the lodgement reference, the assessment progress, and the issued certificate at each step. Construction runs 24–40 weeks depending on size and complexity. Your project manager provides weekly updates with photos and milestone tracking. Every stage is inspected before the next begins.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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. You move in to a finished home, not a defects list to chase.
