Service index

01

Integrated service

Planning & Development Consultancy

Before design begins, the opportunity must be understood.

Planning work frames the decisions that follow: what the site can support, how development may be organized and which constraints need to be resolved before design progresses.

When it happens

Early opportunity, site evaluation and project definition

Relevant project typesResidential / Commercial / Mixed-use / Institutional
Conceptual physical masterplan model illustrating planning and feasibility
01Site intelligence / development framework
Capabilities and documented experience include6 items
  • Urban Planning
  • Master Planning
  • Site Planning
  • Feasibility Consultancy
  • Viability Consultancy
  • Development Planning
Deliverables can involve4 items
  • Development frameworks
  • Site-planning studies
  • Feasibility inputs
  • Planning coordination information
02

Integrated service

Architectural Services

Purpose, context and possibility, given form.

Architectural work translates purpose, site and program into coherent spatial and building decisions, then develops those decisions into information that can be coordinated with engineering and construction.
