The DHS bunk bed with double on bottom measures 198cm long and 143cm wide — the wider double base means this frame needs a bedroom of at least 270cm across for comfortable side clearance. At 144.5cm tall, it sits within standard UK ceiling height constraints without any headroom concern for the upper single occupant. In a standard UK double bedroom of 300×320cm, the frame leaves approximately 78cm on each side — enough for bedside tables and walkway access. Plan the room layout using the full 143cm frame width.
