sous-sol ajouré

@ Odette
I quote you...."Just another way of saying the same thing..."

I do not claim walk-out and daylight are synonyms, on the contrary dear. I say "ajouré" means which lets the day in. So the source text insists on the daylight aspect, not the walk-out aspect.

@ Asker

we posted at the same time! Yes, you need to specify in some way that this is at basement or lower-ground floor level. ("Cellar" would be incorrect if used for habitation or even as a gym/tv/laundry room etc.)

@Asker

Do you have any pics? Is this basement to be used for habitation? In other words is it a selling point that it has this extra habitable space? As said in my response to Eliza, most fire-safety laws would require fire exits, i.e. a door or large windows if used for habitation. Not all daylight basements would meet this requirement as some could have quite small windows
Anyway, a UK equivalent is harder to come up with as the house types are just so different. But, if it is to be used for habitation, then "garden-level basement" would seem to be the most suitable, though some of the houses in the Canadian images MAY also be described in UK terms I think as a split-level-type house with entrance at ground level and rere basement (door) at garden level

Thanks to all for your help and suggestions. Looking at the pictures of the house that I managed to access, the area in question is a lower ground floor with direct access to the garden. I would not call it a basement or cellar.

@ Eliza, @ Asker Look up Google images for "sous-sol ajouré" and you will see lots of these basements HAVE doors so are walkouts. https://www.google.ie/search?q="sous-sol ajouré"&rlz=1C1CHMO...
Odette claims "walkout" and "daylight" are synonyms but they are not as I showed with my link. Curious Eliza that you use exactly the same link!
To be habitable under most fire/planning laws a basement has to have an exit door or large egress windows. Not all daylight basements would be suitable.

This link says, "A daylight basement that has a door that leads to the outside of the house is called a walk-out basement."

As a Brit myself, I'd say that "walk-out basement" is definitely a US expression and not one I've ever heard in the UK.
But are you certain it means what you think? I would have understood it like Odette: just a basement that is not so far underground as to not have windows giving some daylight. I don't see what about 'ajouré' suggests anything about 'having full-height ground-level access', which I assume is what you are meaning by "walk-out"; in the UK, this would often be described as a 'garden flat' if it included accommodation — so perhaps you could call this a 'garden basement' — meaning that it gives out onto the garden level (with the implication, of course, that this is lower than the main house ground-floor level.
