I handle RE2020 certifications for Batilor through an external firm, and honestly, I have nothing to complain about. The construction method is sound, and the implementation is excellent. Most of the houses we've tested are more than half the required standards—with airtightness tests around 0.25/0.30. And, just so you know, having worked with quite a few builders in the area, they offer the best value for money. I even built a Batilor house in 2025, and I'm thrilled with it. I'm sharing my opinion because I've noticed unfounded comments popping up online, and honestly, Batilor really doesn't deserve them. From project manager Mika Mugnier to site supervisor Ludo Martin, you can trust them completely! They do a great job.
