Hanglagen-Bau in Mitte
Mitte is Bezirk Mitte's wilhelminische mietshäuser submarket. Mitte's Spandauer Vorstadt is Berlin's densest cluster of Wilhelminische Mietshäuser (1885-1905) — ~60% of stock is Denkmal eingetragen, and any façade Sanierung needs Landesdenkmalamt approval before Bauaufsichtsbehörde will accept the §63 Bauantrag.
What a hanglagen-bau project looks like here
Mitte's Spandauer Vorstadt is Berlin's densest cluster of Wilhelminische Mietshäuser (1885-1905) — ~60% of stock is Denkmal eingetragen, and any façade Sanierung needs Landesdenkmalamt approval before Bauaufsichtsbehörde will accept the §63 Bauantrag.
Because Mitte sits inside multiple Milieuschutz Erhaltungsgebiete, even kitchen + bath modernisations require a Modernisierungsgenehmigung from the Bezirksamt — and luxury-finish upgrades that exceed a Standard-Modernisierung threshold can be denied as Aufwertung/Verdrängung-driving.
Berlin selbst ist eben — Hanglagen liegen in Brandenburg (Werder, Potsdam Babelsberg, Eichwalde) — Bodenuntersuchung + Hangstandsicherheit nach DIN 4084. In Mitte specifically, wilhelminische mietshäuser stock means hanglagen-bau scope is shaped by the neighborhood's dominant construction typology. Baily's Berlin scoping flow factors milieuschutz §172 baugb and denkmalbereich friedrichstadt into the estimate before a contractor is involved.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
