What makes a bungalow accessible?
In brief: An accessible bungalow complying with DIN 18040-2 has no steps or thresholds in the living area, doors from 80 cm wide (90 cm for wheelchair access), a level-access shower and at least 120 × 120 cm of manoeuvring space in front of every sanitary fitting.
Prefabricated bungalows meet these requirements most easily because the entire living space is on one level. There are no stairs to become an obstacle with age, and every room is connected without steps or thresholds. This makes a bungalow the first choice for age-friendly, future-proof living.

Funding for a new accessible bungalow
KfW supports accessible construction through its “Age-appropriate conversion” programme (KfW 159), with low-interest loans up to €50,000 per residential unit. DIN 18040-2 compliance is required. Many federal states also offer grants or loans for accessible new builds; North Rhine-Westphalia, Bavaria and Baden-Württemberg have their own programmes with grants up to €15,000. If the home also meets a KfW efficiency-house standard, this support can be combined with new-build funding.
