The history of how it happened

A mixed-use anchor at Flora

The corner at Flora before the palace — an open corner of the city beside the Olšany Cemeteries, waiting for an anchor.

The site
“The parcel sat at the corner of the Olšany Cemeteries and Vinohradská, Prague 3. This was not an abandoned site but an open corner of the city waiting for an anchor. A competition, sponsored by the developer Africa-Israel in cooperation with the City of Prague, was won by a local Czech architect, Petr Franta, who had a small office with no experience at large mixed-use modern buildings. Among the many challenges in this complex project was how to connect the metro that stopped at the corner and build next to an active cemetery. Franz Kafka is buried in that cemetery.”

The assignment
“Take the competition scheme and turn it into a buildable project with a set of plans that could be estimated and contracted without risking cost overruns due to errors and omissions. Working with a small group of architects and engineers with little experience providing the sophisticated retail layout, curtain-wall system, mechanical, electrical, plumbing and emergency systems to serve a public facility with many entrances and circulation requirements, in a cost-effective structural design, was no easy task.”
The design
“120-unit shopping arcade spread over four retail floors, occupying roughly the area of two city blocks, with four levels of underground parking beneath and a two-story office component above. The arcade connects directly down into the Flora metro station on Line A. Located at the top of the mall was Cinema City's multiplex and an IMAX — the first, and still the largest, in the Czech Republic, with a 25-metre screen — alongside a food court. The combination of shopping and entertainment made Palác Flóra a destination, not just a mall.”
The competition scheme made buildable — the massing of the two-wing arcade over the metro, and Petr Franta's concept sketch beneath it. The competition scheme made buildable — the massing of the two-wing arcade over the metro, and Petr Franta's concept sketch beneath it.

The site, in his words
“It was a complicated site — sloping two and a half storeys from the corner entrance down to the bottom, with a cemetery on the east and north sides. You had to anchor the retaining walls and the building's structure into the cemetery property, with all the asymmetrical loads that created. Then you connected the metro that stopped at the corner, stacked four floors of retail over a basement of parking, put an IMAX and a cinema and a food court at the top, and offices above that. It was a genuinely complex building.”
The cut at Flora — the site sloping storeys down to the foundation mat, retaining walls braced against the cemetery property on two sides.

The sequencing
“I worked out the retail sequencing with Benny Cohen, the general manager of the most luxurious mall in Israel — how to move people past the storefronts, the escalators and the stairs, how to make them travel the longest distance between certain kinds of stores. Most malls have figured that out today; at the time it was sophisticated.”
The documentation
“When I asked the local team to collect the specs, they handed me a scrapbook — it looked like something a seventh-grader had made, papers and photocopies of different sizes. You can't contract from that. In Europe you bid on bills of quantity, where you itemise literally everything — every cubic metre of concrete, every square metre of drywall by type. I redlined their drawings for the better part of a year to get the project to where we could bid it, and taught them how to sequence and arrange a professional set. The curtain wall, the rotunda and the skylights alone were a six-month bidding process and six months of shop drawings. We bid it around 30 million euros; that building is at least 150 million today.”
The principle
“You're not making a drawing — you're making a building. The drawings ARE the building; you have to think of them as the finished product.”
The result
“Palác Flóra opened on March 20, 2003 — the three years of intensively hard work paying off. It was at the time, and remains, one of the most successful mall buildings in Prague and all of the Czech Republic, and became an anchor in the development of Prague 3, which is one of the most robust places to live and work today. I still have a dear friend, the traffic engineer John Henley, who lives two metro stops away. I was excited and proud to be part of the early days of Prague's evolution into a world-class place to live, work and visit.”
The most fundamental constraint was the site: a subgrade metro to be connected; an active cemetery on two sides of a very large building; and a topography that sloped nearly three stories from the corner street-level entrance.

88,800 m²
956,660 sf — four floors retail + two offices + four underground
The arcade

four retail floors topped by IMAX + Cinema City

The constraint was the site. The build worked around it.

First the open corner at Flora — then the build, five-storey retaining walls anchored into the cemetery property and the metro tied in below.

A little-used public park at Flora became one of the most successful malls in the Czech Republic.

⚑ Notes — open items, for review
  • Cost figures are Scott's recollection (~€30m bid; ~€150m today) — verify before public/investor use.
  • Scott's doc lists Completion March 2003 (spec) but the arc ends at 2004 Opening — both are his; confirm the intended public date (soft-opening/curtain-wall 2003 vs grand opening 2004).
  • Hero: replaced palac-hero.jpg with udu-exterior-corner.jpg (full top-of-building corner shot, blue sky) per Scott's request for a better top-of-building image; old hero preserved in photos/. Confirm.
  • Interior/exterior/progress/site-plan placeholders now filled from the ÚDU AV ČR registry (obj. 507) — 12 wired into the voice_story, 5 more in the gallery. Swap for Scott's own archive shots if/when he supplies them.
  • IMAGE RIGHTS: all udu-* photos are from the Institute of Art History (ÚDU AV ČR) heritage registry. Credit recorded per-photo, but licensing for public/investor use is NOT cleared — confirm permission or replace with Scott-owned imagery before this surface goes public.
