iHoused in the vast red-brick Pension Building of 1887, designed by Quartermaster General Montgomery C. Meigs in a Renaissance Revival style modelled on Roman palazzi, the National Building Museum is America's museum of architecture, design, engineering, construction and urban planning. Its Great Hall runs 316 by 116 feet and is divided by eight colossal Corinthian columns, 75 feet tall and 8 feet across, each built from some 70,000 bricks and painted to imitate Siena marble. The building was designated a National Historic Landmark in 1985, and the museum itself was created by an act of Congress in 1980 as a private non-profit. Alongside long-running shows on housing, LEGO architecture and children's books, it stages temporary exhibitions and a celebrated summer installation in the Great Hall.

Architecture and design made across the American South since 1990, surveying practices that answer to climate, local materials and community need in both cities and rural landscapes.

Models, full-scale masonry replicas, a commissioned robotic sculpture and archival photographs unpack the design and student-led construction of Tuskegee University's landmark chapel.

Andrew Feiler's photographs, drawings, models and a recreated classroom trace the Rosenwald schools built across the segregated South, and the roughly 500 that still stand.

Case studies, data visualisations and video installations on how US cities are remaking their downtowns after the pandemic. First of the museum's three-part Future Cities initiative.

Around 400 souvenir buildings from some seventy countries, drawn from a 3,000-piece collection given to the museum in 2019, from world wonders to factories and department stores.

Open storage putting more than 2,500 previously unseen artefacts on view: models and tools from I.M. Pei, Cesar Pelli and Frank Gehry, Pension Building material and architectural toys.

The museum's 316-by-116-foot atrium, divided by eight Corinthian columns 75 feet tall built of brick and painted to imitate Siena marble. Free to enter, and host to inaugural balls.

A 4,000 sq ft family gallery curated by Leonard Marcus on architecture and construction in children's books, with hands-on activities and environments by David Macaulay and Oliver Jeffers.

Photographs, films, objects and models, including Fallingwater, tour American houses across two centuries, with please-touch walls of real residential construction materials.

Warren Elsmore rebuilds landmarks from all seven continents in LEGO bricks, centred on a 12-foot St Pancras Station made from over 180,000 bricks, with hands-on building areas.
