🏡 Planning a House Extension or Renovation?

A Handy Guide to Help You Prepare and Make the Most of Your Project


✨ Introduction

Extending or renovating your home is an exciting opportunity to reshape how you live. Whether you're craving more space, improving functionality, or adding long-term value, careful planning makes all the difference. This guide brings together expert tips and real-life lessons to help you approach your project with confidence and clarity.

ree

🔍 1. Define Your Why

Before you dive into designs and finishes, take a step back.

Ask yourself:

  • What do I want to achieve?

  • Who is the space for—me, my family, future buyers?

  • Am I solving a problem or creating something new?

Having a clear purpose will help guide your decisions throughout the project.


💷 2. Budget Wisely (And Then Some)

Renovation budgets rarely stay exactly on track.

Make sure you:

  • Include design fees, permissions, structural surveys, and VAT.

  • Allow a contingency of at least 15–20% for unexpected costs.

  • Get multiple quotes—and be wary of offers that seem too good to be true.

Better to over-prepare than be caught out mid-build.


🏛️ 3. Know the Rules

Every area has different regulations.

You may need:

  • Planning permission

  • Building regulations approval

  • Party wall agreements

  • Listed building or conservation area consents

Check early, and speak to your architect or local authority to avoid costly delays.


👷 4. Build the Right Team

Good people make all the difference.

  • Choose an architect or designer who understands your goals.

  • Vet your builder—look at past projects and check reviews.

  • Consider project management support, especially for complex builds.

Trust and communication are key.


🕰️ 5. Plan for the Long Haul

A typical timeline might include:

  • Weeks or months for design development

  • Planning approval periods (8+ weeks)

  • Contractor lead times

  • Construction (which can run 3–9 months or longer)

Start early, and don’t rush—especially if you have deadlines like school terms or new arrivals.


🌞 6. Prioritise Light, Layout, and Flow

Great spaces aren’t just bigger—they’re better to live in.

Think about:

  • Natural light and window placement

  • How rooms connect and feel together

  • Circulation, sightlines, and ease of use

These subtle elements turn a build into a home.


🛏️ 7. Can You Stay Put?

Living through a build can be a challenge.

  • Expect dust, disruption, and restricted access.

  • Consider temporary accommodation, especially if kitchens or bathrooms are affected.

  • If staying, plan safe, contained zones for daily living.

A smoother living arrangement = a less stressful build.


🔌 8. Don’t Forget the Details

Little things can trip you up if left too late.

Plan early for:

  • Electrical points and lighting

  • Storage and cabinetry

  • Heating, ventilation, and insulation upgrades

  • Flooring transitions between old and new spaces

Think through how you'll live in the space, not just how it will look.


♻️ 9. Build for the Future

Design for now, but keep tomorrow in mind.

Consider:

  • Energy efficiency and sustainability

  • Accessibility or multi-generational living

  • Flexible layouts that can adapt over time

Smart planning adds long-term value and resilience.


🧘 10. Expect a Journey

No matter how well you prepare, building projects have ups and downs.

  • Stay in regular contact with your team

  • Keep records of decisions and quotes

  • Be kind to yourself—it’s a big undertaking

Celebrate the milestones and remember why you started.


💬 Final Words

Your home should work for you, not just look good. With thoughtful planning and the right support, your extension or renovation can be one of the most rewarding projects you ever take on.
