  • Two architectural sketch design options

  • Two 3D architectural visualisations (1x per design option)

  • Overarching architectural concept and design direction

  • Proposed material and finishes concept palette

  • Review of relevant Council planning controls and site constraints

  • Coordination of preliminary DA/CDC approval pathway advice by an independent Town Planner*

  • Coordination of an indicative construction cost assessment by a qualified Quantity Surveyor*

  • Recommendations and next steps

  • Meeting 1 – Initial Briefing & Site Measure: A consultation to discuss your brief, project aspirations and requirements, and obtain a measure of the existing spaces.

  • Meeting 2 – Feasibility Study Presentation: Presentation and discussion of the design options, planning considerations, indicative costs and recommended next steps.

An obligation-free first step towards creating a more functional, considered and timeless home.

This service is suitable for detached houses where you are considering a renovation or extension involving changes to floor area, internal layouts, walls, glazing and/or roof form.
