Why Your Home Project Takes Longer Than the Drawings Suggest

The drawings look finished long before the house is. Understanding the phases of a project helps you plan realistically and spot the places where your own decisions can save or cost the most time.

The phases most projects pass through

  1. Pre-design. Gathering information: your goals, your budget range, the survey, the zoning and any special conditions affecting the site.
  2. Schematic design. Early options for layout and massing, reviewed with you until a direction is chosen.
  3. Design development. Refining the chosen direction: materials, systems, structure and details are coordinated.
  4. Construction documents. The detailed drawings and specifications used for permit and construction.
  5. Permitting. Submission, plan check, response to review comments, and permit issuance.
  6. Bidding or contractor selection. Pricing the project and choosing a builder, if not already done.
  7. Construction. The build itself, with inspections along the way.

Where the time hides

Permit review is the phase that surprises people most. Review times vary widely between cities and project types, and comments from reviewers often require drawing revisions and another round of review. Specialist reports, such as a geotechnical investigation on some sites, or energy compliance documentation, can also add steps. Ask your architect which of these are likely to apply to you instead of expecting a single number.

What you control

What you do not control

Weather, material availability, inspection scheduling and the unknowns revealed once walls are opened are outside anyone's control. A good schedule includes room for them, and a good professional will tell you which parts of the timeline are firm and which are estimates.

A schedule is a set of assumptions. The best ones say what the assumptions are.

If you are weighing a large project, start with the remodel-or-rebuild question, or ask what to expect in the early phases through the contact form.
