How the architecture process works from scratch to handover

The six stages of an architecture project, what you receive at each one, and how construction oversight works.

An architecture project moves through six stages: briefing, preliminary study, schematic design, legal/permit design, detailed design and construction oversight. Each stage has clear deliverables and a client approval before moving forward. The full process usually takes four to eight months, depending on complexity and the size of the property.

The biggest source of anxiety in a project is not cost: it is a lack of predictability. Knowing exactly what happens at each stage, what you approve and when, transforms the whole experience.

The six stages of the project

  1. 01Briefing and diagnosis — an in-depth conversation about routine, schedules, sensitivities, budget and deadlines, plus the technical survey of the property or site.
  2. 02Preliminary study — first proposals for spatial organisation, massing and siting, presented in floor plans and 3D images so a direction can be chosen.
  3. 03Schematic design — the chosen concept is developed: final dimensions, main materials, lighting and fitted furniture.
  4. 04Legal design — documentation for approval by the city, the fire department and other bodies, when applicable.
  5. 05Detailed design — construction detailing, specifications, finishes schedule and coordination with engineering and building services.
  6. 06Construction oversight — periodic site visits, technical responses to the builder and checking what was built against what was designed.

What you receive at each stage

  • Technical floor plans, sections and elevations to scale.
  • 3D images of the main rooms for confident decision-making.
  • Specification booklet with materials, brands and alternatives.
  • Finishes list and descriptive report for budgeting.
  • Site visit reports during construction, with photographic records.

How long it takes

Apartment interiors usually take two to four months of design. Full single-family homes take four to eight months. Construction follows, with its own timeline — and that is exactly where oversight prevents rework and unexpected costs.

How the client is involved

Each stage ends with a presentation and a formal approval. You decide between alternatives presented with pros, cons and budget impact — never on a design that is already closed. We work in person in Curitiba and remotely throughout Brazil, with video meetings and full material sent ahead of each session.

A good project is a project decided on paper. Every doubt resolved before construction costs a fraction of what it would cost afterwards.
