You’ve found the perfect plot or home and are excited to begin your project — but the whole process can feel confusing and a bit overwhelming at first. Starting a building project in London is an exciting step, yet it’s important to understand how the process works and make sure you’re well prepared. Doing so will help everything run much more smoothly from the very beginning.
To make things easier, we’ve created a helpful checklist to guide you and ensure you start your project on the right track.
Step 1: Initial Conversation & Site Visit
Everything starts with a simple conversation. No pressure, no technical jargon.
We’ll usually ask:
- What are you trying to achieve?
- Is it a full home build or a home extension?
- Do you already have drawings from an architect?
Then we arrange a site visit. This is where things become more practical. You’ll notice we’re not just looking at the space — we’re thinking about structure, access, neighbours, and what’s realistically possible.
For most people, this stage is more about clarity than decisions.
If you’re still exploring options, speaking to experienced home builders London early on can save you from going down the wrong path.
Step 2: Design & Planning Stage
This is where your ideas start turning into actual plans.
If you don’t already have one, we’ll typically involve an architect to prepare drawings. Depending on the project, a structural engineer may also be needed — especially for extensions involving steel beams (RSJs) or structural changes.
Now, here’s where it depends:
- Some projects require planning permission
- Others fall under permitted development
In London, especially areas like Hammersmith or Chiswick, planning rules can be quite specific. So getting this right early matters more than people think.
At the same time, we make sure everything aligns with building regulations, so you don’t run into issues later.
Step 3: Quotation & Project Breakdown
Once drawings are ready, we prepare a detailed quote.
Not just a number — a proper breakdown.
We’ll walk you through:
- Materials
- Labour
- Timeline
- Key stages of the build
In my experience, this is where trust is built (or lost). If something isn’t clear, we’d rather explain it properly than rush you into a decision.
And yes, sometimes budgets need adjusting — that’s normal.
If you’re comparing quotes, make sure you’re comparing like-for-like. Cheaper isn’t always better, especially in residential construction.
Step 4: Approvals & Pre-Construction Setup
Before any work starts, we handle the necessary approvals.
This may include:
- Finalising planning permission
- Submitting details for building regulations approval
- Coordinating with your architect and structural engineer
We also plan logistics:
- Access to the property
- Material deliveries
- Neighbour considerations (important in London)
It might feel like things are moving slowly here, but this stage prevents bigger problems later.
Step 5: Construction Phase
This is where things finally get real.
Depending on the project, the process usually includes:
- Groundworks and foundations
- Structural work (including RSJs if needed)
- Walls, roofing, and external structure
- Plumbing, electrics, insulation
- Internal finishes
You’ll notice there’s a rhythm to it — some weeks feel fast, others slower. That’s just how building works.
We keep communication open throughout. Most homeowners appreciate regular updates, even if it’s just a quick check-in.
If you’re working with home extension builders near me, this is the stage where coordination and experience really show.
Step 6: Final Checks & Handover
Towards the end, we go through everything carefully.
This includes:
- Final inspections for building regulations compliance
- Snagging (small fixes and finishing touches)
- Making sure everything works as expected
- We don’t just hand over keys and disappear. If something needs adjusting, we sort it.
Because honestly, the last 5% of a project often matters the most to homeowners.

Frequently Asked Questions
Do I need planning permission for every project?
Not always. Some extensions fall under permitted development, but in London it can vary by area. It’s always safer to check early.
When should I involve a structural engineer?
Usually when structural changes are involved — like removing walls or installing RSJs. For extensions, it’s almost always required.
How long does the process take?
It depends on the size and complexity. Smaller extensions might take a few months, while full builds take longer. Planning and approvals can also affect timelines.
Will I need an architect?
Most projects do. An architect helps turn your ideas into workable plans and ensures everything meets regulations.
What’s the biggest mistake homeowners make?
Rushing the early stages. Skipping proper planning or ignoring building regulations can cause serious delays later.
A Final Thought
If I’m being honest, no two projects are ever exactly the same.
Some run perfectly smooth. Others have small surprises — that’s just part of construction, especially in older London properties.
But what really makes the difference is having a clear process and the right people involved from the start.
For most homeowners, once you understand the steps, it all feels a lot less complicated — and a lot more manageable.
