A Commitment To Quality,
Craftsmanship & Trust
My journey in the property and construction industry began as a property developer between 2010 and 2013, providing valuable experience in project planning, development, and delivering successful residential outcomes. Since 2014, I have been leading my own building projects through Trajcon, focused on creating exceptional homes built with quality, precision, and integrity.
At Trajcon, we believe that every exceptional home begins with a clear vision and is brought to life through meticulous planning, skilled craftsmanship, and unwavering attention to detail.
Our mission is simple: to transform architectural concepts into homes that reflect the aspirations, lifestyles, and long-term goals of our clients.

Over the years, we have built lasting relationships with homeowners, architects, consultants, and developers by consistently delivering projects with professionalism, reliability, and a commitment to excellence.

Victorian Building Regulations & Pre-Contract Checklist
Residential construction in Victoria is governed by the Building Act 1993, Domestic Building Contracts Act 1995, NCC 2022 7-star NatHERS energy efficiency standards, and municipal ResCode. Before signing any contract, verify these 6 essential consumer protection checkpoints:
Check Builder Registration
Ensure your builder holds an active Domestic Builder (Unlimited) licence with the Victorian Building Authority (VBA).
01Review Contract Terms
Execute a standard Major Domestic Building Contract (HIA or Master Builders) with a clearly defined fixed-price scope and transparent allowances.
02Domestic Building Insurance
DBI is legally mandatory in Victoria for all domestic construction valued over $16,000, protecting your project from start to finish.
03Soil & Foundation Engineering
Confirm foundation data and geotechnical soil classifications (AS 2870) are fully accounted for before slab engineering sign-off.
04Permits & Approvals
Establish whether your site requires council town planning permits, special overlays, or independent building surveyor approvals.
05Statutory Milestone Payments
Verify progress claims match Victorian statutory caps: 5% deposit, base slab (10%), frame (15%), lockup (35%), fixing (20%), handover (10%).

Builder Due Diligence & FAQs
Frequently Asked Questions
10 Questions to Ask Before Signing a Building Contract in Victoria
Before committing to any builder, ensure your contract scope and site management are completely transparent:
- Have you built homes of similar architectural complexity?
- Who coordinates the working drawings and engineering?
- Are all council and statutory building permits included?
- Is the price a genuine fixed sum with defined specifications?
- What items are Prime Cost (PC) or Provisional Sums (PS)?
- How are design variations documented, priced, and approved?
- Who will be managing daily construction on my site?
- How often will I receive progress reports and site visits?
- What stage inspections occur prior to final handover?
- What certificates and warranty documents will I receive?
A custom home builder coordinates and constructs a residential dwelling built entirely from individual architectural plans, rather than repeating standard volume catalogue floorplans. The custom builder coordinates site surveys, soil testing, engineering design, town planning permits, building approvals, material procurement, licensed specialist trades, and staged building inspections from site establishment to final occupancy certification.
Custom home costs are determined by site conditions (soil reactivity class and topography), architectural design complexity, structural engineering requirements, total floor area, selected building materials, internal joinery and fixtures, statutory council overlays, and NCC 2022 7-star NatHERS energy efficiency compliance. A transparent builder will provide an itemised, fixed-price HIA contract based on working drawings and engineering.
A typical single or double-storey custom home takes approximately 8 to 16 months from the issuance of the building permit to practical completion and handover. The exact timeframe depends on site complexity, architectural scale, basement excavation, weather contingencies, and material lead times. The construction period is formally specified in your major domestic building contract.
Yes. Trajcon Builders & Developers specializes in challenging Melbourne sites, including sloping blocks, narrow urban infill allotments, and irregular parcels. Challenging blocks often require custom stepped concrete slabs, split-level framing, bored piers, subfloor ventilation, and engineered retaining walls to maximize space, daylight, and views while maintaining council ResCode compliance.
In Victoria, residential building projects valued over $10,000 must use a Major Domestic Building Contract under the Domestic Building Contracts Act 1995. The most widely accepted industry standard contracts are issued by the Housing Industry Association (HIA) or Master Builders Victoria (MBV). These contracts legally protect consumers by defining fixed pricing, progress milestone payments, completion dates, and statutory warranties.
Any modification to architectural plans, structural engineering, or fixture specifications after the building contract is executed is handled through a formal Variation document under Victorian law. The builder details the exact cost and timeline impact, and the variation must be signed in writing by both the owner and the builder before the altered work is carried out on site.
Under the Building Act 1993 and Victorian building regulations, every new custom home carries statutory warranties: 6 years for structural defects and 2 years for non-structural defects. In addition, builds over $16,000 are backed by Domestic Building Insurance (DBI). Trajcon also includes a dedicated post-handover defects liability maintenance period to ensure every finishing detail meets our master craftsman standards.
