Isla Renwick · Architect · Edinburgh

Buildings that sit in the ground as if they were quarried from it.

I design houses, studios and small civic rooms in stone, brick and timber across Scotland, and I stay on site until the last joint is pointed.

Strata kilmorack house 1

Kilmorack House

A new house on a Beauly hillside, built from the sandstone lifted out of its own foundations and roofed in larch that will silver with the fence posts.

Houses
Strata granary 1

Leith Granary

Six flats and a shared workshop inside a bonded warehouse that had stood empty since 1994, with every brick kept and every window widened by exactly one course.

Retrofit & conversion
Strata fife 5

Kincraig Links Pavilion

A sandstone and blackened-timber pavilion on the dunes that reads as a steading from the road and a lantern from the beach.

Civic & community
Strata courtyard 1

Braid Hills Courtyard House

A low concrete house wrapped around a walled courtyard, so that the wind goes over the top and the garden gets the sun.

Houses
Strata studio 1

Corstorphine Garden Studio

A single concrete room at the end of a long garden, for a printmaker who needed north light, a sink and a door that locks.

Studios & garden rooms
Strata stair 3

Portobello Stair

A new precast stair threaded through a Victorian villa so that three floors read as one house again, lit from a single rooflight at the top of the well.

About

The person at the drawing board

Isla Renwick in the studio on Candlemaker Row

I am Isla. I trained in a school that still made us draw by hand and I have never quite stopped: the first idea for every project is a pencil section on tracing paper, and the last is a note on site about the pointing.

My work is mostly houses, a few studios and the occasional small civic room, almost always in stone, brick or timber, and almost always somewhere the weather has an opinion. I take on four or five projects a year so that I can be on every site myself.

Clients

What the people who live in them say

She was on the scaffold more than the plumber was. Our house is warm, quiet and entirely made of things that were already on the farm, and she argued with the mason on our behalf for eleven months.
Catriona and Doug Mackay Kilmorack House
The drawings were the clearest I have priced in thirty years of building. Every joint was drawn, every stone was accounted for, and when something arrived short she was there the same afternoon with a decision.
Ewan Ritchie Main contractor, Quarry Steading
The trust wanted a building that would disappear from the road and we got one. What we did not expect was that the cafe would become the village's living room. The committee still argues about the bench.

Why I still point the last joint myself

An architect on site is either a nuisance or a colleague. Here is how I try to be the second one, and why the last day of a build is the one I never miss.

20 June 2026 Site notes

Site notes: Braid Hills, week nineteen

The roof is on, the courtyard walls are up, and the wind has finally found something to argue with. A fortnightly diary entry from the concrete house on the hill.

Have a site, a ruin or a cold room that needs thinking about?

Tell me where it is and what stands on it now. I take on four or five projects a year and I am booking for 2027.
