A side-return that brought light into a dark 1930s semi

The situation before

A family in a classic Luton 1930s semi with a narrow galley kitchen and an unused alley down the side.

What triggered it

“I didn't want any nasty surprises. We'd heard horror stories about budgets doubling.”

How we challenged the brief

We agreed a fixed fee and a realistic build budget up front, and resisted the temptation to over-glaze — one well-placed roof light did the heavy lifting on light.

The design solution

A side-return infill plus a modest rear extension, opening the ground floor into a bright kitchen-diner with a clear sightline to the garden.

+£55,000

An estimated £55,000 of added value, a home that finally works for family life, and a project that came in on the budget agreed at the start.

There were no nasty surprises. The fixed fee was the fixed fee.
