How to Plan, Budget, and Manage Your Extension
Planning a home extension is an exciting opportunity to create more space, add value to your property, and tailor your living environment to your needs. However, without careful planning and management, it can become overwhelming. In this guide, we’ll walk you through the key steps to plan, budget, and manage your extension effectively, ensuring the process is as smooth as possible.
Step 1: Start With a Clear Vision
Before diving into the details, take some time to clarify your goals. Ask yourself:
- Why do I need this extension? (e.g., more space, better functionality, increased property value).
- What purpose will the new space serve?
- How will it fit with the existing layout and style of my home?
By answering these questions, you’ll have a clear starting point. It’s also worth gathering inspiration from magazines, Pinterest, or architecture blogs to refine your ideas.
Step 2: Set a Realistic Budget
Budgeting is one of the most critical aspects of any home extension project. Here’s how to approach it:
-
Research Costs
- Get a general idea of extension costs in your area. In London, for example, extensions can range from £2,000 to £3,000 per square metre, depending on the quality of finishes.
-
Factor in Hidden Costs
- Planning permissions and building regulation approvals.
- Professional fees for architects, structural engineers, and surveyors.
- Unexpected expenses, like dealing with old pipes or unforeseen structural issues.
-
Set a Contingency
Always allocate 10–15% of your budget as a contingency for surprises during construction.
Step 3: Work With the Right Professionals
The success of your extension often hinges on choosing the right team.
- Architects: Working with a skilled architect can save you money during construction. A well-thought-out design will optimise space, materials, and construction methods, helping avoid costly changes or errors down the line.
- Builders: Finding the right builder is crucial. At Extension Plans, we can recommend experienced builders who consistently deliver quality work and understand how to implement designs efficiently.
- Project Managers: If your extension is large or complex, hiring a project manager can save time and reduce stress. We can also recommend trusted project managers who will oversee your project and ensure it stays on track.
Step 4: Obtain Planning Permission and Approvals
Depending on the size and scope of your extension, you may need to apply for planning permission. Some extensions fall under Permitted Development, which streamlines the process.
To avoid delays, check with your local council and ensure your design adheres to the rules. An architect or planning consultant can help navigate this process.
Step 5: Plan the Timeline
Home extensions don’t happen overnight. Here’s a general timeline:
- Architectural Design: 1–5 weeks.
- Planning Permission (if needed): 8–12 weeks.
- Construction: 2–6 months, depending on the complexity.
Working with an experienced architect can streamline the design and approval process, saving both time and money. Clear, precise plans will minimise misunderstandings during the construction phase.
Step 6: Manage the Construction Phase
When the work begins, it’s crucial to stay on top of things.
- Regular Check-Ins: Visit the site regularly to ensure progress is on track and address any issues early.
- Communication: Keep an open line with your builders and project manager.
- Stay Flexible: Unexpected challenges may arise—be prepared to adapt your plans if necessary.
With the right builders and project manager, many of these responsibilities can be delegated, giving you peace of mind while your extension takes shape.
Step 7: Focus on Finishing Touches
Once the main construction is complete, the finishing touches bring your extension to life. Choose fixtures, fittings, and décor that complement the rest of your home while reflecting your style.
