A common question we get from clients is, “How long should I allow before starting my home extension or refurbishment project?”
Many homeowners are eager to get started immediately, but several steps must be completed before any work can begin on-site. From obtaining statutory approvals to finalising the design, these preparatory stages are essential to ensure a smooth construction process.
In this guide, we’ll outline the key steps involved and give you a realistic timeline for launching your project.
1. Statutory Approvals: The Essential First Step
Before construction work begins, you’ll need to obtain several statutory approvals.
These typically include:
- Planning permission
- Building regulations approval
- Party wall agreements
- CDM (Construction Design and Management) regulations compliance
Each process can take time, and delays are common, so factoring them into your project timeline is essential.
Failing to secure these approvals before starting work can lead to costly interruptions and legal issues. Be prepared for statutory approvals to add weeks or even months to your project schedule, depending on the complexity of your plans and local regulations.
2. Measured Survey and Design Phase: Aligning the Vision
Once you engage us, we’ll begin the measured survey and design phase. This is when we’ll take detailed property measurements and develop accurate architectural drawings.
Throughout this phase, you’ll have multiple discussions with our team to ensure the design aligns with your vision.
Finalising your design during this phase is crucial, as making changes later during construction can be costly and cause delays. This stage typically takes 3 to 6 weeks, depending on the scale of your project and the complexity of your requirements.
3. Planning Submission and Building Regulations
After your design is finalised, we’ll prepare the planning submission. We may sometimes begin drafting building regulations drawings concurrently, but this comes with some risk if the planning authorities request changes.
Obtaining planning permission can take at least 8 weeks or more, depending on the local council and any potential objections. Once planning permission is secured, finalising the building regulations drawings can add 7 to 8 weeks to the timeline.
4. Party Wall Process: Navigating Neighbour Relations
You must follow the Party Wall Act procedures if your project involves party walls. This step can run parallel with building regulations but may take up to 2 months, depending on how quickly your neighbours respond and whether they agree to the proposed works.
It’s necessary to avoid future disputes and ensure that all parties are on the same page before construction starts.
5. Allow 6 to 8 Months Before Construction Begins
When planning your timeline, you should allow 6 to 8 months from the initial engagement to the start of construction. This accounts for:
- Statutory approvals (planning permission, building regulations)
- The measured survey and design phase
- Finalising construction drawings
- Completing the party wall process
By allowing sufficient time for these steps, you’ll avoid unnecessary delays and ensure the build process is as seamless as possible.
Final Thoughts: Plan for a Smooth Construction Process
Proper preparation is key to a successful home extension or refurbishment project. By allowing 6 to 8 months before the start of construction, you ensure that all necessary approvals, design decisions, and construction details are finalised.
Rushing this process can lead to costly delays and complications, so take the time to plan thoroughly.
