M5 Bygg

Swedish Standards

The standards we bring from Sweden to Dubai.

Written guides to exactly how we build — building regulations, waterproofing, plumbing, tiling, electrical safety, inspections and accountability. The same rules we hold ourselves to on every project.

Building Regulations

Boverket's Building Regulations: the legal baseline we build to

What BBR is, the functional requirements that shape a home, and how Sweden's industry rules turn the building code into verifiable site practice — the legal floor beneath everything M5 does.

Ceramic Tiling

1 guide

BKR / BBV: the Swedish rules for tiling a wet room properly

Wet-Room Painting

1 guide

MVK: painted wet-room surfaces that are built to last ten years

Not every wet-room wall is tiled. Where surfaces are painted, Sweden's MVK rules make sure the system is genuinely watertight or water-resistant — and engineered for a decade of service.

Electrical Safety

Electrical safety: wiring a wet home the way Sweden requires

Water and electricity share the walls of a bathroom. Sweden's Electrical Safety Act puts hard rules on who may wire it, how zones are protected, and how the work is checked — and M5 holds to that discipline in Dubai.
