Design & Build
From Your First Idea to Your Finished Home. We Are With You Every Step.
Great homes do not start with a quote. They start with a conversation, a vision, and a process built around you. At BGH Construction, we have developed a clear and structured journey that takes you from your very first idea all the way through to handover, with complete transparency, expert guidance, and no surprises along the way.
STAGE 1: CONCEPT AGREEMENT
Every project begins with understanding what you want to achieve and whether it is realistically achievable within your budget. After an initial site meeting and discovery call, we enter into a Concept Agreement with you.
Under this agreement, BGH Construction engages our architect on your behalf and briefs them on your scope, budget, and design direction. The architect meets you on site and works with you to develop initial concept plans, typically including floor plans and elevations, giving you a clear picture of what your project will look and feel like before any major commitment is made.
Once concept plans are complete, we refine your initial ballpark figure so everyone is aligned on investment before moving to the next stage.
The Concept Agreement is a paid agreement that covers the cost of the concept design phase. It is your first step toward a project that is properly thought through from the start.
STAGE 2: PRELIMINARY BUILDING AGREEMENT
Once you are happy with the concept and the investment figure is within budget, we move into a Preliminary Building Agreement. This is where the real detail is developed.
Under the Preliminary Building Agreement, BGH Construction coordinates and manages all of the following on your behalf:
-
Detailed architectural plans prepared for DA, CDC or CC approval
-
Structural and civil engineering
-
Geotechnical and hydraulic reports
-
BAL rating, environmental assessment, BASIX and NatHERS compliance
-
Council or private certifier application and approval management
During this stage we also connect you with our interior designer to begin your selections, kitchen, bathrooms, flooring, tiling, fixtures and fittings, and exterior finishes. Having your selections confirmed early ensures your Fixed Price Proposal is accurate and complete.
BGH Construction charges a fee for the preparation of your Fixed Price Proposal, specifications, and construction schedule, the amount varies depending on the scale and complexity of your project. We present the completed proposal to you in person and walk through every detail together.
The Preliminary Building Agreement is a paid agreement that covers the design, documentation, approvals and proposal preparation phase of your project.
STAGE 3 — FIXED PRICE CONSTRUCTION CONTRACT
Once your approvals are granted, your selections are confirmed, and you are happy with the Fixed Price Proposal, we move into a formal HIA Building Contract for the construction of your project.
This is a fixed price contract, the price you sign is the price you pay. Your proposal is typically 40 to 50 pages long and documents every inclusion, exclusion, specification and detail of your project. There are no hidden costs and no shortcuts.
From the moment construction begins, you have access to real time project updates through our Buildertrend app, weekly site meetings, and a dedicated site supervisor managing your project from start to finish.
The only time the contract price changes is if you request additional works outside the agreed scope, or if genuine unforeseen site conditions are encountered, both of which are communicated to you and approved in writing before any additional costs are incurred.
WHY BGH CONSTRUCTION
Most builders separate design and construction into different businesses, leaving you to coordinate between an architect, an engineer, and a builder who have never worked together before. The result is miscommunication, budget blowouts, and a process that is far more stressful than it needs to be.
At BGH Construction, we bring all of it together. One team. One relationship. One clear process from first idea to finished home.
We take on Custom homes & complex large scale renovations and additions projects that require real expertise to deliver, and we back every project with a 278 point quality checklist, post handover care at three and six months, and a commitment to you that goes well beyond the day we hand over the keys.
