A modern extension the family in Luton are proud to open the doors on
In Luton (LU2), a growing family had run out of room. Family visits meant squeezing round a table that wasn't built for it, and the house no longer felt like the fresh, modern home they wanted to be proud of. So we designed an extension around them.

The challenge
A house too small for the life happening in it
The family had reached the point most homeowners recognise: the house that once fit them now didn't. Rooms felt tight, family visits meant shuffling furniture and eating in shifts, and day-to-day life had a background hum of needing more space.
What mattered to them wasn't complicated — a home that felt modern, that looked and felt fresh, and that they could be genuinely proud of when people came round. Somewhere comfortable enough that having family to stay didn't feel like a squeeze.
And the usual worry sitting underneath it all: spending real money and ending up with something that still didn't fit, or a design and planning process that dragged on with no clear end in sight.
Our approach
An extension designed around how this family actually lives
This was a Made-for-You Design project, so before any lines were drawn we looked at how the family actually used their home — where they ate, how they liked to host, what more space really meant for them day to day.
We agreed a fixed fee up front, so there were no surprises on cost, and we visualised the design so they could see and feel the finished extension before committing to it — the timber-clad addition, the run of glazing opening onto the garden, the room it would give them for family visits.
We handled the planning process on their behalf, so the technical side of getting the scheme approved wasn't something they had to learn from scratch. Their job was to tell us what mattered and make the decisions that were genuinely theirs — we carried the rest.
A growing family in Luton who wanted a more comfortable, modern home with room to host — and real pride in the place they live.
The outcome
A modern extension they're proud to open the doors on
The result is a warm, timber-clad extension with full-width bi-fold doors that open the kitchen and living space straight onto the garden — the kind of room that makes hosting family easy rather than a squeeze.
It's a home that finally matches the life going on inside it: modern, comfortable, and unmistakably built around how this family actually lives.
Good to know
Extending in Luton
Do I need planning permission for a house extension in Luton?
Not always. A lot of single-storey rear extensions fall under permitted development, provided they stay within set size and height limits — meaning no full planning application is needed. Larger extensions, or homes in a conservation area, are more likely to need one. We check exactly where your project stands before any design work begins.
How much of my garden will a rear extension in LU2 take up?
It depends on the depth of the extension and how close it comes to your boundaries, which is exactly why we look at your plot and permitted development limits early on. As a guide, single-storey rear extensions on semi-detached homes are typically capped at 3m under permitted development, or up to 6m under the wider Larger Home Extension scheme — we'll tell you which applies to your home in Luton.
How much does an architectural designer cost for a home extension?
At Diogel we agree a fixed fee before any work starts, rather than a percentage of the build cost, so you know the price from day one. What's included — design, planning drawings, the application, and site visits — is set out clearly, with no surprises along the way.
Do you design home extensions in Luton and across Bedfordshire?
Yes. We've completed hundreds of home projects across Bedfordshire, Milton Keynes, the North West and North Wales. You can see the spread of completed projects on our project map.
