Home renovations & building restoration
Built like our own home.
A small London builder, working on a small number of projects at a time, in Walthamstow and the postcodes around it.
We take every project on as if we were going to live in it. The detail is the work. The work is what we sign our names to.

How we work
01
Consultation
We come and look at the project, listen to what you want to achieve, and put together a written scope and a fixed price. The consultation is free, takes about an hour, and doesn’t oblige you to anything. If we’re not the right fit, we’ll tell you, and we’ll usually know someone who is.
02
Build
A small team, on site every day, working through the project room by room. One number to call and one person who answers. Materials are agreed before they’re ordered. Changes are agreed before they’re made. The price you sign is the price you pay.
03
Handover
A renovation is finished when the snag list is closed. We walk every project ourselves before we hand it over; the list should be short by the time you see it. After handover, we stay on the hook for twelve months — anything that needs adjusting, we come back and adjust it.
What we do
A small list, done well.
We focus on a small number of services and do each of them properly. If your project doesn’t sit on this list, get in touch anyway — we’ll let you know whether it’s a fit, or recommend someone who would be a better one.

About JAG
A small builder. A short list of projects at a time.
I’m James. JAG is a small team based in Walthamstow, working mostly in the Victorian and Edwardian terraces of East and North London. The kind of houses we live in ourselves. We know how they’re built, where they fall down, and what hides behind the lath and plaster.
We work on a small number of projects at a time so each one gets the attention it needs. The same faces are on your site from the first day to the last.
— James Saunders, JAG Construction London

Choosing & working with a builder
How to read a builder’s quote
A quote is a document. The important parts are often what’s missing. How to read one properly, how to compare them fairly, and what the gaps tell you before you sign anything.
Period property
What hides behind the walls of a Victorian terrace
When you open up a house that was last properly touched 130 years ago, you’re not dealing with surprises. You’re dealing with the same building, built the same way. Here’s what we find.
