Why Altbau? 7 reasons to love a classic apartment

"Altbau" is more than a construction date — it's a feeling backed by hard building physics. Here are the seven objective advantages, followed by the honest counterarguments.

The seven reasons

1. Ceiling height. 3.2 to 4 metres instead of 2.5: more air, more light, taller mouldings. Height is the single most important factor for how a home feels — and for resale value.
2. Solid brick walls. 40–60 cm of brick store heat and dampen sound. Summer heat stays outside, and the neighbour's party sounds quieter than in prefab blocks.
3. Cross-ventilation. Windows on two façades (or a through-room) = 5 minutes of shock ventilation replaces the entire air. Often impossible in modern blocks with windowless halls.
4. Through-rooms and enfilades. Double doors in a row create depth and flexibility — rooms connect or separate as the day requires.
5. Original features with history. Stucco, boards, tiles, fittings: restoring them is cheaper than replacing them — and unmistakable. No new build can be "authentically 1900".
6. Location. Altbau districts are usually the most sought-after: tree-lined streets, mixed use, short distances. Much of the value sits in the neighbourhood, not just the building.
7. Renovability. Brick and timber structures can be maintained for decades. A new build with sealed-in technology often has no second life after 40 years.

The honest counterarguments

• Energy: an unsanitated Altbau sits at 150–250 kWh/m²a — triple a new build. Windows, roof and heating can cut that to 60–90; our calculator shows the cost.
• Timber-beam floor acoustics: footsteps upstairs are audible. Carpets and decoupled underfloors genuinely help.
• Renovation backlog when buying: budget 15–25% of the purchase price for pending work — or negotiate the discount accordingly.
