ADU / accessory dwelling in Kalverstraat
Kalverstraat is Amsterdam's 15th-century pilgrim-route alignment submarket. Kalverstraat's pre-1500 pilgrim-route alignment means modern parcel widths are irregular at 3.2-7.8m, and any structural alteration that crosses the medieval property-line palissadeerpaal lines triggers an Erfgoedwet article 5.10 archaeological-watch permit.
What a adu / accessory dwelling project looks like here
Kalverstraat's pre-1500 pilgrim-route alignment means modern parcel widths are irregular at 3.2-7.8m, and any structural alteration that crosses the medieval property-line palissadeerpaal lines triggers an Erfgoedwet article 5.10 archaeological-watch permit.
Because Kalverstraat carries roughly 80,000 pedestrians daily, Veiligheidsregio Amsterdam-Amstelland enforces a stricter brandcompartimentering rule on residential-above-retail than elsewhere in Centrum — every kitchen-relocation project needs a brandscheidings-rapport prior to VTH submission.
The street's 1888 Magna Plaza (former post office) at the north end is a Rijksmonument category I that casts a 100m archeological-influence zone affecting basement waterproofing on every neighbouring residential conversion.

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.

Kalverstraat adu / accessory dwelling projects typically run $195K–$570K. Kalverstraat's 15th-century pilgrim-route alignment stock, combined with unesco buffer zone, puts most mid-complexity projects in the $383K range. Baily scopes the exact band once you describe the work.
