Custom Home Builder — Your Block, Your Design, Your Price
A custom home is designed from scratch for your specific block dimensions, orientation, slope, household size, lifestyle, and budget. Not a modified template. Not an off-the-shelf plan. Every Buildana custom home is unique — because every block and every family is different. That's the difference between a custom home builder and a project home builder.
Buildana is a licensed custom house builder serving greater Sydney — headquartered in Western Sydney with deep expertise across Fairfield, Liverpool, Cumberland, Canterbury-Bankstown and Blacktown. We handle everything — site analysis, design and construct, engineering, CDC fast-track approvals (10–15 business days for eligible builds) or full DA management, and fixed-price construction from slab to keys.
Single-storey family homes from $450K. Double-storey custom builds from $600K. Narrow block specialists for lots under 10m wide. Every custom home comes with a fixed-price contract — every inclusion itemised, no provisional sums, no allowances that blow out. The price in your contract is the price you pay. 6-year structural warranty under the Home Building Act 1989.

Every Buildana custom home is designed from scratch — no templates, no compromises.
What Is a Custom Home?
A custom home is designed from scratch for your specific block dimensions, orientation, slope, household size, lifestyle, and budget. It is not a template modified to fit. It is not an off-the-shelf plan with cosmetic changes. Every room, every wall, every window is placed with intent — based on how your family lives and what your block demands.
This is what separates custom home builders from project home builders. A project home starts with a fixed design and asks: “can we make this fit your block?” A custom home starts with your block and asks: “what is the best possible home for this site?”
Buildana has designed and built custom homes on standard suburban blocks, narrow lots under 10m wide, sloping sites, corner blocks, and battleaxe lots across Sydney. Every build starts with a site analysis — not a catalogue.
Custom Home Designs — Single Storey, Double Storey, Narrow Block
Single Storey
150–250m²
$450K–$900K
Suits standard Western Sydney blocks. Accessible, cost-efficient, popular with families and downsizers. Open-plan living, alfresco connection, no stairs.
Double Storey
250–400m²
$600K–$1.3M+
Maximises smaller lots and adds bedrooms without sacrificing backyard space. Upper floor typically houses bedrooms, lower stays open for living.
Narrow Block
Under 10m wide
$500K–$1M+
Very common in Fairfield, Cumberland and Canterbury-Bankstown. Requires specific engineering: courtyard layouts, tandem garaging, vertical massing, open-plan lower floor.
How Much Does a Custom Home Cost in Sydney? (2025)
Custom home price depends on size, design complexity, finish level, and specific site conditions. Here are the key cost factors that affect your custom built home cost:
Block Slope
Sloping sites increase slab and retaining wall cost. Cut and fill may be required.
Soil Classification
M-class reactive clay is common across Fairfield and Liverpool — adds $10,000–$30,000 to slab design.
Floor Plan Complexity
Every additional corner, angle and level change adds structural cost. Efficient layouts save money.
Finish Level
Standard, quality and luxury tiers. Biggest cost difference is kitchen, bathrooms and flooring.
Approval Pathway
CDC is faster and cheaper. DA required for heritage, flood or complex designs — adds $5,000–$15,000.
Site Access
Restricted access (narrow driveways, shared access) increases crane and delivery costs.
Not included in construction cost: land purchase, demolition (if applicable), council contribution fees (s7.11 on DA pathway), upgrades beyond standard inclusions.
