Our Process.

Client focussed from the start.

Step 1: Let's get acquainted.

Let’s talk

Getting to know you, your wants, needs and desires is paramount to creating a unified build brief that will act as a road map for your completed home. Our Home Owner Specialists will talk you through all of the possibilities. We will talk about layout design, finishes and any additional extras you would like to include. Don’t be afraid to push the boundaries, we like nothing better than a good challenge. Once we have an idea of what you would like to accomplish with your new home, we can get started on the paperwork. Don’t worry, with our help, it won’t take too long.

Preliminary Works Agreement (PWA) and/or Preparation of Plans Agreement (PPA)

Once we’ve have your ideal home design, finishes and specifications finalised, we can sign the PWA or PPA documents. This is a formality to agree upon what work we will be completing and draft a build schedule so you know the time frame of the process.

Finance review

A review of finances establishes the real budget for the project and your borrowing capacity which, let’s face it, is fundamental to what you want to create. It is important that we are realistic about what is achievable within your budget. Don’t be fooled by those who offer you dreams but then deliver a substandard reality. We want a realistic budget that you can live with and deliver a product that meets or exceeds your expectations.

Sales sketch

Once finance has been approved, we will order a ‘sales sketch’, which is a rough plan and outline of your home. 

Step 2: Dotting the i’s and crossing the t’s.

Let’s get the paper work out of the way. We understand that this step can be daunting, especially if you don’t understand industry terminology or processes. Don’t worry, we will guide you through it step-by-step.

Land contract

If you purchased your block independently, you or your real estate agent will need to provide the completed land contract to us. If you purchased a house and land package directly through us, then we will organise this on your behalf.

PPA and plans

The sales sketch outlined in Step 1 are prepared, finalised and signed by both Hamlen and the home owner. All structural changes must be finalised at this point.

Building contract

The final HIA Building Contract is signed by both Hamlen and the home owner.

Finance approval

This is the final step of the paperwork. We will need a letter from your bank that acknowledges your loan approval. This step can take up to 30 days, so if you are in a particular hurry to get the building process started, we advise looking into this as soon as possible.

Our aim is to be completely transparent and ensure that we all understand the contract clearly. So please, don’t hesitate to ask as many questions as you like. We’re here to help and want you to be 100% comfortable with the final contracts. 

Step 3: Preparing for the build.

Site survey

A land surveyor conducts a detailed inspection and services assessment of the block and reports it’s findings to Hamlen. This tells us exactly what we are dealing with and highlights any issues that need to be resolved before we start building. 

Soil testing

Geotechnical testing and analysis of your blocks soil conditions is required so that engineers can design the necessary footings and concrete slab for your home. 


A structural engineer will design the necessary site works and structural engineering required to create your new home.

Design and styling / pre-start

Architectural floor plans and elevations are created. Selections of fittings, fixtures and finishes both internally and externally are completed.

Planning approval/ developer approval (if required)

Working drawings

The final working drawings are completed by Hamlen. The detailed designs and specifications required for construction are handed over to the supervisor.

Building certification

An independent review of the working drawings and specifications is conducted to ensure that the build abides by the planning approval of the BCA (building code of Australia) and meets all relevant Australian Standards. Once building certification is complete by either private certification or shire the plans are stamped and a building permit is issued. 

Step 4: Your home is born.

Site start

Your block of land will be prepared so that it is ready to build on. Site excavation will commence, underground connections will be laid and finally, the concrete slab will be poured. Upon completion of slab pour a 21.5% (includes 6.5% deposit) progress payment is due.


You home starts to come together when the bricklayer sets out the walls in accordance with the working drawings. Once approved by our supervisor, bricklaying commences to plate height and the doorframes are installed. Once doorframes are installed a 25% progress payment is due.


After brickworks reaches plate height the roof framing is installed, followed by roof cover and gutters. A 20% progress payment is now due.


This is a major milestone in the building process and is literally when your home can be ‘locked up’. Brickwork, wall cladding, windows and doors are complete. Once lock-up stage is complete a 18.5% progress payment is due.

Final fixings and fit-off

We begin the final touches, which includes dry lining the walls with plasterboard, installing cabinets and joinery to your kitchen, tiling all wet areas (bathrooms, laundry etc.), bench tops are laid, and shower screens, mirrors and door furniture are installed. The plumbing and electrical connections are also finalised.

Practical completion inspection (PCI)

The construction of your home is now nearing completion and our administration team will book in your practical completion inspection. Your site supervisor will meet you at your new home and demonstrate all of its features and functions. Any minor defects or incomplete items will be collated into an inspection list and agreed with you for rectification. Upon reaching practical completion the final progress payment of 15% is due as well as any additional variations you may have ordered.

Hand-over of keys

Once final payment has been received we will hand over the keys to your new home. Congratulations. 

Step 5: Caring for your new home.

After care and maintenance

Our service doesn’t end when we give you the keys. At hand over, we also present you with a Home Care Manual that provides you with information about your new home. It even comes with a defect checklist that you can fill in should any problems arise. All of our homes come with a six month Warranty Service Inspection and Review where we will address any issue that arises. Further to this, we will aim to complete any defects within four weeks after the inspection.
