The Leyland annex that gave two grown-up sons a place of their own
In Leyland (PR25), a widow wanted her two grown-up sons to have proper independence — space that was genuinely theirs — without losing the closeness of family life next door. An old, unstable double garage wasn't doing anyone any good sitting empty. So we turned it into the answer.

The challenge
A garage going to waste, and sons who needed their own space
The existing double garage was past its best — not stable enough to safely add a second storey as it stood — while both of her sons had reached the stage where they needed genuine independence: their own front door, their own space, without moving away from a mother who wanted to stay close.
It's a brief a lot of families will recognise in outline, even if the details are their own: grown-up children who still need support, and a home that hasn't caught up with what the family actually needs now.
She'd also been let down before — a previous builder had left snagging work unresolved — so trust in getting this one right, from people who'd see it through properly, mattered as much as the design itself.
Our approach
A separate space, designed around this family
This was a Made-for-You Design project, so we started with what independence actually needed to look like for this family — a self-contained space with its own kitchen and living area, and a bedroom, built by demolishing the unstable garage and rebuilding in its place.
Because the property sits in a rural setting backing onto open fields, we flagged early that a heritage impact assessment would likely be needed and that the planning process would probably take longer than a typical extension — better to know that upfront than be surprised by it later.
We agreed a fixed design fee before any work began, and visualised the scheme so she could see the new annex — and how it would sit alongside the house — before committing to it.
A widow in Leyland who wanted her two sons to have independent living space of their own, created by rebuilding an old garage rather than losing the home they already loved.
The outcome
A place of their own, without leaving home
The design turns a garage that had become dead weight into a genuine two-storey annex — independent living space for her sons, built where an unused, unstable structure used to stand.
It gives the whole family what they actually needed: proper independence for her sons, and the peace of mind of still having them close by.

Good to know
Extending in Leyland
Can I convert or rebuild a garage into independent living space in Leyland?
Often, yes, though a self-contained annex with its own kitchen and living space is more likely to need a full planning application than a straightforward garage conversion, particularly if you're rebuilding rather than converting as-is. We check your specific circumstances before any design work begins.
Does a rural or countryside setting affect what I can build?
It can. Properties in rural settings, near listed structures, or with heritage sensitivity sometimes need a heritage impact assessment as part of the planning application, which can extend the timeline. We flag this early, rather than let it become a surprise partway through.
How much does an architectural designer cost for an annex conversion?
We agree a fixed fee before any work starts, rather than a percentage of build cost, so you know exactly what the design and planning work will cost from day one.
Do you design garage conversions and annexes in Leyland and South Ribble?
Yes, we've completed home projects across Leyland, South Ribble and the wider North West. You can see examples of completed work on our project map.
