The Luton family who got their modern kitchen without the budget spiralling
In Luton (LU5), a growing family wanted a home that finally felt modern and comfortable — somewhere they could take real pride in. The worry holding them back wasn't the design. It was the fear of costs creeping up once work began. So we agreed the fee before a single wall came down.

The challenge
Wanting more from the house, without an open cheque book
The family's home had fallen behind what they needed and how they wanted to live. It wasn't dramatic — just a kitchen and living space that felt dated and cramped, the kind of thing you notice every day but keep putting off fixing.
They wanted the obvious things: somewhere more modern, more comfortable, somewhere they'd feel proud to be in. But like most homeowners looking at an extension, they'd heard the stories about costs creeping past the original number, and they didn't want to sign up for that kind of uncertainty.
What they needed wasn't just a nicer kitchen. It was a clear number, agreed early, that wouldn't move once the work was underway.
Our approach
A fixed fee, agreed before anything started
This was a Stay on Budget project, so before any design work began we agreed a fixed fee for our part of the job — no percentage-of-build-cost creep, no surprise invoices later on. They knew what the design and planning stage would cost from day one.
We then focused the design on real, visible improvements within that budget: a bright, open kitchen-diner with space to cook, eat and sit together, and doors that open the room out to the garden. Every decision was about getting genuine value into the space, not adding extras that pushed the number up.
They didn't need to chase us for costs or wonder what was included — the fee was set, the scope was set, and we kept them updated at each stage so there were no surprises.
A growing family in Luton who wanted a more modern, comfortable home — and the pride that comes with real improvements — without an open-ended budget.
The outcome
A modern family kitchen, and a budget that held
The result is a light-filled kitchen-diner that opens onto the garden, with room for the whole family to cook, eat and spend time together — the kind of space they can be genuinely proud of.
Just as importantly, the number they agreed at the start was the number they paid. No spiralling costs, no last-minute extras — just real improvements to the home, delivered within the budget they set.
Good to know
Extending in Luton
Do I need planning permission for a kitchen extension in Luton?
Not always. Many single-storey extensions fall under permitted development if they stay within the size and height limits, so no full application is needed. Larger extensions, or homes in a conservation area, are more likely to need planning permission. We check exactly where you stand before any design work begins.
Does a previous extension affect what I can add in LU5?
It can. Permitted development rights are often calculated cumulatively, so an extension already built on the property can reduce what you're allowed to add without a full planning application. We check your property's planning history as a first step, so you know your real starting point.
How much does an architectural designer cost in Luton?
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 Luton and Bedfordshire?
Yes. We've completed hundreds of home projects across Milton Keynes, Luton, the North West and North Wales. You can see the spread of completed projects on our project map.
