Riehmers HofgartenWilhelmine Berlin · Kreuzberg

Berlin’s building law required one yard 5.34 metres square. Riehmer built two private streets instead.

The smallest courtyard a Berlin house could have was the space a horse-drawn fire pump needed to turn in: 5.34 × 5.34 m. On a plot more than 170 metres deep, the master mason Wilhelm Ferdinand August Riehmer left room for 110 of them — laid out two private streets, gave the houses behind them the same fronts as the houses on the street, and went to law for the permits. The work ran from 1880 to 1899. Almost all of it is still here.

01The law’s square

The law asked for one square of open ground. Riehmer left room for 110

Riehmers Hofgarten fills the inside of a block in the Tempelhofer Vorstadt, now Kreuzberg, between Yorckstraße, Großbeerenstraße and Hagelberger Straße. The plan below is drawn from the surveyed outlines of its houses. The inner ground is open to the public in daylight.

5.34 m × 5.34 m

The smallest yard the law allowed: 5.34 metres a side

The Baupolizeiordnung, Berlin’s building-police code, set the smallest courtyard a house could have at the space a horse-drawn fire pump needed to turn in: 5.34 m by 5.34 m, 28.5 square metres.

one square

One square made a lawful house

A house that left this much light and air at the back was a lawful house. With the street plan, that measurement shaped the Mietskaserne — the “rental barracks” tenement, with its rear houses behind courtyards.

183 m

A plot more than 170 metres deep

Wilhelm Ferdinand August Riehmer was a Maurermeister, a master mason, and the client. The Landesdenkmalamt records his plot as T-shaped and more than 170 metres deep. Measured on today’s plan, from the Yorckstraße front to the Hagelberger Straße front, it is 183 metres.

two streets

Instead of yards, two private streets

Instead of courtyards behind courtyards, Riehmer laid two private streets through the block, arranged in a T. Their cobbles, lamps and railed garden islands are still there.

behind the street

The houses behind got the street’s fronts — and its rents

A house on one of the private streets, built to the standard normally kept for street buildings — which the listing says commanded a high rent. Here the houses on the private streets are drawn in the same colour as the houses on the public street.

110 squares

Room for 110 of the law’s squares

Fill all the open ground inside Riehmer’s own boundary with the law’s square, and 110 fit. They are not courtyards — there are no walls between them. They count how many times the law’s idea of enough space fits into the space Riehmer left.

46 squares

The largest open space alone holds 46

Walk in under the Yorckstraße portal and keep going. The cobbles run the length of the block and turn west for Großbeerenstraße; the largest single piece of open ground the plan finds between the houses is 46 squares. The building law would have been satisfied by one of them.

02He had to sue for it

The authorities resisted for years. Riehmer went to law, house by house

What he wanted did not fit the Bebauungsplan, the city’s street plan of 1862, which laid out the blocks of the new districts round the old city. Permission came one house at a time, and some of it only through the courts — which is why the complex took 19 years.

03Three campaigns, 1880–1899

19 years, three building campaigns — and Riehmer drew none of them

The complex is one idea and three building campaigns, and Riehmer drew none of them himself. He was a Maurermeister and the client; the listing names the men who designed each phase. Building began at the far end, on Hagelberger Straße, and finished on Yorckstraße. The Landesdenkmalamt’s description dates the Großbeerenstraße houses to 1882–83; its own table gives two campaigns. Both are drawn.

04He was not the first

He did not invent the private street. He made the houses behind it as fine as the street

Riehmers Hofgarten is usually told as the invention of the private residential street in Berlin. The listing says otherwise, and names the two that came before it. And Riehmer had tried the idea himself: 12 years before the Hofgarten, in 1868, he built a house of a similar type at Mehringdamm 40.

What was new here, then.

Not the private street. The scale of it, and the fact that the houses behind were finished to the standard normally reserved for the houses in front — which is what the listing says let him charge a high rent for a courtyard flat.

05After the war

The façades are repaired, in a campaign that only happened because of substantial public subsidy. On 4 August 1964 the complex was made a geschützter Baubereich, a protected building area; other accounts date its first protection to 1953. Both dates are shown below.

The flats are comprehensively modernised, some plans changed. A garden house largely destroyed in the war is replaced by a cinema in steel, glass and aluminium, and the historic garden layout is largely reinstated.

When the cinema went in is disputed: the Landesdenkmalamt places it in the early 1970s, other accounts in 1985/86. From the late 1990s the façades are repaired again, in stages.

07The record

What the record settles, and what it does not

Settled

The Landesdenkmalamt Berlin dates the complex 1880 to 1899, lists twenty-one addresses in three phases, names Heinrich Mittag, Paul Opitz and Otto Mrosk as the designers and Wilhelm Ferdinand August Riehmer as the client, records the plot as more than 170 metres deep and T-shaped, records two private streets arranged in a T, and dates the protection order to 4 August 1964.

Source: Landesdenkmalamt Berlin · other accounts

Disputed, and shown here as disputed

The listing's description dates the Großbeerenstraße building to 1882–83; its own phase table gives 1881–1883 and 1884–1885. Both are drawn. Accounts of when the war-damaged garden house was replaced by the cinema differ: the Landesdenkmalamt says the early 1970s, other accounts say 1985/86. Some accounts date the first protection of the complex to 1953 rather than 1964.

Not established

No source consulted gives the number of flats, the area of the plot, or the area of the open ground; those figures are therefore not stated here, and the count in this story is of squares on a surveyed plan, not of anything the archive counts. No source consulted places any named resident at this address.

Source: Landesdenkmalamt Berlin · other accounts

Who lived here: Beamten, Offizieren, selbständigen Kaufleuten und einigen Akademikern und Künstlern — officials, officers, merchants trading on their own account, and some academics and artists. The listing describes the tenancy; it does not list it, and no source consulted places a named resident at this address.

Riehmers Hofgarten · 1880–1899

Berlin’s law would have been satisfied by one square of open ground. On his own ground Riehmer left room for 110 — and built the houses behind as finely as the houses in front.
