Please explain what is Stage 2 design development?

Stage 2 Design development is the preparation of all documentation in order to obtain a detailed and accurate tender for your specific project, either a new home, major renovation or a home improvement.

Your H4 Project manager will give you a quote for your specific project up front, so there are no surprises and you have absolute clarity for your specific project costs.

As an example a 300m2 low set home on a flat block, will have completely different costs to a 300m2 three level major renovation.

Also you may want to supply or look after certain materials or processes  ie; colour selections, town planning approvals, contract administration etc, You are in control of the process and choose the options that you may consider more or less important for you.
