The design process
-
During this stage, we will meet with the client to ascertain the brief, budget and other parameters for the project. It is useful in this stage to view the existing space, undertake an internal measure and commission a survey to produce a set of existing information.
-
This stage involves the preparation of design ideas in response to the client’s brief. Designs will be presented to the client to ascertain the best way forward.
-
During this stage we develop the client’s chosen concept into greater resolution to establish the required size, construction, finishes and massing, with another client checkpoint to ensure we are on the right track.
-
Once the developed design has reached agreement with the client, we can prepare all of the necessary documentation and coordinate with the required constulants to produce an application for Council, be it a Development Application or Complying Development Certificate.
-
Once planning approval is received, we commence with detailed construction documentation through the preparation of drawings, schedules and specifications required to allow the project to be constructed. This stage includes the Construction Certificate required by Council in order to commence works.
-
This stage involves the procurement of the project for construction, which may include Tendering to a selection of contractors to seek competitive pricing, or liaising with a preferred contractor.
-
During the site works, we as architect can impartially administer the Contract between client and contractor, helping to ensure outstanding design decisions are adequately managed, maintaining adherence to the project programme and budget, and the client’s vision.
-
We love to stay in touch with our clients to hear feedback about the finished product, assist with any queries where possible and evaluate the performance of the building.
