Description

Recreating a New York landmark

New York's Flatiron Building, completed in 1902 to a design by Daniel Burnham, is often cited as one of the city's first skyscrapers and is best known for the triangular footprint created by the street junction it occupies. LEGO® Architecture set 21023 reproduces that distinctive silhouette, paring the structure down to its key proportions and facade lines. At 471 pieces, it sits in the mid-size range for the Architecture theme, enough to render details like the building's rounded prow without reaching the scale of the largest landmark sets.

No minifigures, by design

Like every set in the Architecture line, this one comes without minifigures — the focus stays entirely on the building's form and its character as a scale model rather than on play scenes. LEGO typically includes a booklet with background information on the real building alongside sets like this one. For anyone assembling a skyline from several Architecture models, the Flatiron Building sits naturally alongside other New York sets such as the Empire State Building or Rockefeller Center.

A limestone-toned colour palette

Tan and dark tan dominate the colour scheme, standing in for the warm limestone of the real facade, with light bluish grey used for architectural detailing and a handful of trans-brown pieces likely representing windows or the building's tapered tip. That restrained but deliberate palette is typical of the Architecture theme, which prioritises accuracy over colourful variety. The parts list on this page shows exactly how those four colours are distributed across the model.

A low unique-parts count for a 471-piece build

With only 52 unique parts across 471 total pieces, this is one of the lower part-variety builds covered on this site, pointing to a lot of repeated elements, which suits the layered construction of a facade. Anyone after tan or dark tan building elements for their own architectural projects can use the searchable parts list here to see exactly which shapes and quantities the set includes.
