Week 25, Day 1:

• You have to look very carefully to see any difference in the main photo, but most of the external windows and doors are now installed.

Week 25, Day 1

Two of the four Internorm HS330 lift-and-slide doors

The other two doors are just visible in the background

One of the HS330 doors installed in the Open Plan Living Area

The ground floor insulation and polished concrete slab still needs to be installed (due next week) so the finished floor level will be just below the door threshold.

There’s another matching sliding door to the left of this one, and a smaller one to the right.

The east elevation, with all doors and windows installed

Temporary installation of PetWalk Passivhaus cat-flap

There’s a cream-coloured cover panel to go over the inside of the cat-flap (and a dark grey one for the outside).
