From Google:

“A brick veneer wall is constructed by having a non-structural external layer, usually with bricks and it is backed by an air cavity. The innermost element of this type of wall is structural can consist of wood, metal framing or masonry. A brick veneer construction has many advantages over solid masonry.”

.... I think the house is timber frame.  :-\

Tunnie...you're going to have to ask the builders to put us out of our misery.

Its a movement joint.

Here's a link to a very boring NHBC standard which offers some explanation.

Old houses didn't need them as lime mortar allowed a greater degree of movement.  :y

Its unlikely to be a brick rainscreen, joints are far too rubbish for a factory made panel.

Also mortar is different shades suggesting 'hand' not 'machine' batched and the efflorescence in the face of the brickwork suggests proper bricks badly stored, you very rarely see that in factory made rainscreen panels.

If it was a rainscreen panel, based on where the joint is, its over 3m wide and they don't generally make them that big as they are too fragile

Its not uncommon to have a timber frame house with a proper brick facade, that's what I'd suggest is what this house is

I am still puzzled as to why the builder found it necessary to put this joint in. Is it commonly done nowadays?

New houses have to last the 10 years of the NHBC guarantee without major repairs,
but houses built on ground prone to movement , not virgin ground, but built up,or drained wetland or brownfield  or area prone to clay heave or subsidence are going to move,
put a movement joint in, if and when the land settles, either the joint will close, OR IF it opens the joint up ,the builder has to send the YTS trainee round with a mastic gun to snot over the joint to keep the sucker proud new homeowner happy.

that's why all new builds are magnolia inside, when the house settles, said YTS trainee will be sent to fill cracks and touch up the magnolia paint .

Are they bricks or brick veneers (you often see this with veneers)?

That tiling around the Velux is very shoddy!

Don’t know difference in bricks?

Being new build, found many issues.  :(

Solar thermal was installed by standard plumber who knew nothing about solar.

Fixed all issues though, until now

Not the solar thermal, the Velux, tile falls short on the right side (there are ways to stop this happening with a it of careful planning and/or cutting).

Thanks Dave, well explained. :y

PS This would have worked on my house which was built on made up ground, and suffered settlement cracks.
