Altbau or Neubau? Choosing the Right Berlin Apartment

The question every buyer asks me

Almost every client who comes to me with a shortlist ends up asking the same thing sooner or later: Altbau or Neubau. It sounds like a simple preference, like choosing between two kitchen finishes, but it touches almost every part of a Berlin purchase — the mortgage, the running costs, the tax return, and how quickly you could resell if your plans changed. I want to walk through what actually separates the two, using the facts rather than the folklore that tends to circulate around this topic.

What Altbau actually means

In Berlin, Altbau is not a vague label for “old building”. It refers to a specific stock, mostly built during the Gründerzeit and Wilhelminian era, roughly 1871 to 1914, with a second wave from the 1920s and 1930s. That period of construction is why so many Berlin apartments share a recognisable feel: ceilings are often 3 metres or higher, original floorboards (Dielen) run underfoot, stucco detailing survives on cornices and ceiling roses, and room layouts tend to be generous rather than optimised down to the square metre. These are the qualities that draw people to neighbourhoods such as Prenzlauer Berg and Charlottenburg, where entire streets of Altbau facades were preserved.

The trade-off sits behind the walls rather than in the room proportions. Energy certificates on Altbau apartments typically land in class D to F, and a buyer should budget for energy-related work as part of the purchase, not as a surprise afterwards. Germany’s building energy act (Gebäudeenergiegesetz, GEG) also attaches certain duties to a change of ownership — replacing an old boiler, insulating accessible heating pipes, and insulating the top-floor ceiling where it separates heated space from an unheated roof. None of this is unusual for the building type, but it belongs in the numbers from day one, which is exactly what a proper buying-costs estimate should reflect before you sign.

What Neubau offers instead

Neubau, new construction, starts from a different set of assumptions. Efficiency standards are built in rather than retrofitted, which shows up directly in lower running costs for heating and hot water. The building itself carries a statutory builder’s warranty (Gewährleistung) of five years, which gives a new owner a defined recourse period that simply does not exist with a building from 1905. Level access and lifts are far more likely to be standard, which matters if accessibility or long-term liveability is part of the plan.

The apartments themselves usually read differently: ceiling heights are more modest, and the sense of period character that defines classic Altbau is largely absent, replaced by cleaner lines and more efficient floor plans. A meaningful share of Neubau in Berlin is also sold off-plan, before the building is finished, under the framework of the Makler- und Bauträgerverordnung (MaBV), which governs staged payments tied to construction progress rather than a single completion payment. That structure is worth understanding in detail before committing, since it changes both the financing timeline and the risk profile compared with buying something you can walk through today.

Price and the investment case

Neubau in Berlin generally trades at a meaningful premium per square metre over a comparable Altbau apartment in the same location — I will not attach a specific figure to that, because it moves with the market and the specific street, but it is consistent enough to plan around. For anyone buying as a landlord rather than an owner-occupier, the tax treatment also differs. Linear depreciation (Absetzung für Abnutzung, AfA) runs at 2 percent per year for older stock, and at 3 percent per year for new builds completed in 2023 or later.

	Altbau	Neubau
Typical era	1871–1914, plus 1920s–30s	Newly built
Ceiling height	Often 3m+	Generally lower
Energy class	Typically D–F	Built to current efficiency standards
Warranty	None (existing building)	5-year Gewährleistung
AfA (landlords)	2% p.a.	3% p.a. (completed 2023+)

Character, liquidity, and which one suits you

If I had to name the single most liquid segment of the Berlin market, it would be prime, renovated Altbau in the classic districts. Buyers recognise it immediately, financing it is straightforward, and it tends to hold demand across market cycles in a way that is harder to say with certainty about newer stock still building its own resale history. That does not make Neubau the wrong choice — for someone who wants predictable running costs, a warranty, and no energy retrofit ahead of them, it can be the more comfortable purchase. It is simply a different bet, and knowing which one you are placing matters more than any general preference for old or new.

I usually walk clients through this trade-off using the specific apartments on their list rather than in the abstract, since the right answer changes with the building, the street, and what the buyer actually wants from the next ten years. If that would help, a 60-minute consultation is a practical place to start, and the fee is credited in full toward the buyer-representation engagement if we go on to work together.
