Hello everyone,
We are currently planning the construction of a single-family house, without a basement, approximately 180sqm (1937 sq ft) of living space, 1.5 stories, with an exterior wall area of about 270 sqm (2906 sq ft).
The architect has designed the exterior walls using 36cm (14 inches) Poroton blocks with a plaster facade (white). Now we would prefer a clinker brick appearance and are facing the following decision:
Option 1: Handmade clinker bricks; additional cost of 100€ per sqm; however, this would mean not using Poroton 36 blocks anymore but instead using Euromac2 wall elements. The calculation was based on Wienerberger clinker bricks at a price of 40€ per sqm. The different wall construction is stated to be cost-neutral.
Option 2: We keep the wall construction with 36cm (14 inches) Poroton blocks and apply a clinker brick slip (thin brick veneer) to the facade.
For this, the architect has 1. not yet provided a price estimate and 2. advised against it for quality reasons.
I am interested in the following points:
1. Is the price parity between the Poroton 36 and Euromac2 wall constructions realistic?
2. Approximately what additional cost compared to plaster (or conversely what cost saving compared to the stated handmade clinker brick option) should I expect?
3. Pros and cons of both options.
Thanks in advance.

Specifically regarding corners: in solid prefabricated houses (with wall panels made of aerated concrete blocks or similar), it is not uncommon for the facing brickwork to be applied at the factory — each panel individually, so the corners are not "interlocked." I don’t see much difference in quality compared to facing bricks without corner pieces (which even DIYers hardly do anymore). Since I’ve read this from you several times now: do you not consider the expansion joint at the corners necessary?
Here, all houses have this joint — except one, where the father-in-law (retired) did it himself.
I also find it more aesthetically pleasing when there is no joint. However, when I asked my supervisor and some bricklayers, they said an expansion joint is necessary from 12.00 m (39 feet 4 inches) onward and advisable below that, because the masonry moves and cracks could develop.

And I claim that you simply don’t recognize well-made brick slip facades as such. Because you can’t tell they are.Well, that’s just your opinion without any basis. I could just as well say, "Your profile says you are a female teacher, but I claim that you are actually a dog groomer named Pablo" – which wouldn’t make much sense, right?
Maybe sometimes it's best to just accept differing opinions?
Regarding the additional costs: In Schleswig-Holstein, labor costs are the key factor, and practically everyone here has experience with brick construction.
1) Monolithic: aerated concrete base plaster with mesh, finish plaster, and paint — the least expensive in terms of labor.
2) External thermal insulation composite system (ETICS): aerated concrete, polystyrene insulation, filler, mesh, top coat, and paint — the second cheapest option.
3) Brick veneer: aerated concrete, insulation, brick cladding — only slightly more expensive than option 2 in labor costs. Thin brick slips would be comparable to brick veneer in terms of labor.

BUT: You can tell. Window reveal, window lintel, Prefabricated brick lintels with steel angles—even horizontally built—can also be seen in solid brick cavity walls. The hardcore traditional bricklayers already turn up their noses if the window sills are not roll layers. That’s not quite “old school,” but my uncle Alex would have said: “Back in the day, we had an emperor.” 🙂

Don’t you think that expansion joint at the corners is necessary? The butt joint I described is simpler from a production standpoint. So far, I haven’t had the impression that it always would be connected with a joint designed as an expansion joint. However, I would agree that this expansion joint should be considered part of proper execution for certain panel sizes (and at joints).
