Planning a home extension in Hampshire? Whether you’re in Four Marks, Horndean or Ashurst, knowing what to expect — and when — is crucial for a smooth, stress-free experience.

Here’s a realistic timeline breakdown of a typical home extension project, from first ideas to the final finish.

📅 Stage 1: Initial Consultation & Concept Design (2–4 weeks)

Meet your architect, discuss your ideas and define your goals.
This includes:

• Site visit and measurements
• Initial concept drawings
• Feasibility check for planning permission

Tip: Start early — especially in areas like the South Downs or Alresford, where restrictions apply.

📄 Stage 2: Planning Application & Approval (8–12 weeks)

If required, your architect will submit your planning application to your local council (e.g. East Hampshire, Test Valley, or New Forest).

• Decision time is usually 8 weeks
• Allow time for feedback, revisions, or delays
• In conservation areas like Beaulieu or Wickham, expect stricter oversight

🧱 Stage 3: Technical Drawings & Building Regulations (2–4 weeks)

After planning approval, your architect produces detailed drawings for:

• Builders
• Structural engineers
• Building control compliance

At this stage, you’ll also begin getting contractor quotes.

🛠 Stage 4: Construction Phase (8–20 weeks depending on size)

• Small single-storey extension: 8–12 weeks
• Two-storey or large wraparound: 16–20 weeks
• Bad weather, supply issues or change requests may cause delays

Tip: Choose experienced Hampshire-based builders who are used to working with local architects.

🧽 Stage 5: Finishing Touches & Snagging (1–2 weeks)

Final checks, fittings, paintwork, and tidy-up. Your architect (if managing the build) will help with the sign-off and final inspections.

✅ Total Project Time: 6 to 10 months

Starting early and working with an experienced Hampshire architect will save you time, stress, and money — and keep your project running smoothly.
