Liverpool · L16
The L16 family who no longer had to guess what came next
In Liverpool (L16), a growing family wanted more from their home — more space, and a proper connection to the garden they'd been staring out at through a cramped back door. What made them hesitate wasn't the idea. It was not knowing what the process actually involved, or who was making which decision when. We gave them a clear plan from the first conversation.

The challenge
Wanting the change, unsure of the process
The house worked, but only just. Living space was tight, the connection to the garden was an afterthought, and the family had reached the point most homeowners recognise — wanting more room and more light, but not knowing where to start.
It wasn't the design decisions that worried them most. It was the process: who handles planning, what the council will and won't allow, what happens if something gets rejected, how long it all takes. Without clear answers, an extension can feel like a leap into the unknown.
They didn't want to become experts in planning policy. They wanted someone to tell them plainly what was possible, what wasn't, and what came next.
Our approach
Clear answers, at every stage
This was a Clear Guidance project, so our focus from the first conversation was making the process legible — what permitted development covered, where a full planning application was needed, and what the realistic timeline looked like for their L16 property.
We handled the planning submission itself, so they weren't left interpreting council correspondence on their own, and we talked them through the design in plain terms — how the new layout would open the living space to the garden, and why each decision was being made.
At each stage, they knew what was happening, what they needed to decide, and what we were handling. No guessing, no chasing us for updates.
A growing family in Liverpool who wanted more living space and a proper connection to the garden — and clear guidance through a process that can otherwise feel like guesswork.
The outcome
More space, and no uncertainty along the way
The result is a home with genuinely more living space and a much stronger connection to the garden — bifold doors that open the extension out, rather than the tacked-on back room they had before.
Just as important to the family was how the process felt: clear from the start, with planning handled and decisions kept simple, so the stress usually associated with extending a home never really showed up.
Good to know
Extending in Liverpool
Do I need planning permission for a rear extension in Liverpool?
Many single-storey rear extensions fall under permitted development if they stay within the size and height limits, so no full application is needed. Larger or wraparound extensions, or homes affected by an Article 4 direction, are more likely to need a full planning application. We check exactly where you stand before design work begins.
How long does planning permission usually take for a home extension?
A standard householder planning application typically takes around 8 weeks once validated by the council, though it can run longer if further information is requested. We build a realistic timeline into the plan from the outset, so there are no surprises on timing.
How much does an architectural designer cost for a home extension in Liverpool?
At Diogel we agree a fixed fee before we start, rather than charging a percentage of the build cost, so you know the price up front. What's included — the design, planning drawings, the application and site visits — is set out clearly, with no surprises.
Do you design home extensions across Liverpool and the North West?
Yes. We've completed hundreds of home projects across the North West, Milton Keynes, Luton and North Wales. You can see the spread of completed projects on our project map.
