  • h4-meet-the-team
  • h4-project-road-map
  • h4-schematic-design
Step 1

Concept Design

Based on the information gathered in the Pre-Design phase, this is where your design really comes to life and is one of the most exciting steps in the process.

We start to adjust and refine the initial schematics into a realistic and buildable design, including 3D perspectives for a more comprehensive visual understanding.

Ask our Designer for a detailed Step by Step Process and inclusions.

Step 2

Design Development

During Step 2, your working drawings will be finalised.

Once we refine the minor amendments, a full set of working drawing documentation will be produced, which is suitable for local authority building approval as well as construction.

Almost all residential projects will require the input of specific consultants to enable some development approvals or final Building Approvals.

Examples of external consultants include: Engineering, Town Planning, Demolition, Ventilation unit design, NATHERS/Basix reports, Bushfire, Private Certification, etc

At H4, we work with some of the best industry professionals but also offer you the flexibility to select your own.

Construction Costs Calculator

This calculator helps you to estimate the minimum and maximum range of your possible project costs.

Costs provided are an average price, allowing for preliminaries, builders profit and overheads. The calculator can provide no more than a rough guide to the probable average cost of your project and can vary significantly based on site conditions, design, fit out and general scope of works.

At H4 one of our key differences is our process, which is designed to ensure that you have early information about your project cost, without having to spend thousands upfront.
