What to Include in Your House Extension Brief (With Free Template)

Starting a home extension? One of the best things you can do is create a clear project brief, especially before speaking to an architect.

Here’s what to include in your brief, plus a simple downloadable outline to get started.


📝 Why a Brief Matters

Your brief is your roadmap. It helps your architect understand your:

  • Goals and priorities
  • Budget and timeline
  • Must-haves and deal-breakers

A clear brief = fewer surprises, faster decisions, and better results.


📄 What to Include in Your Extension Brief

  1. Your Goals
    What’s the problem you’re trying to solve?
    E.g. “We need more space for family meals and entertaining.”
  2. Rooms and Functions
    List what you want the new space to include.
    E.g. open-plan kitchen, utility room, office nook.
  3. Style and Look
    Do you prefer modern, traditional, or something in between?
    Include images or Pinterest boards.
  4. Budget Range
    Give an honest idea — e.g. £50K–£70K — so your architect can design accordingly.
  5. Timing
    When would you like the project to start and finish?
  6. Planning Considerations
    Mention if your home is listed, in a conservation area, or under any restrictions.

🧠 Architect Tip

Live in Winchester, Alton or Brockenhurst? Local planning policies can vary — a detailed brief helps your architect anticipate what’s possible.
