📝 Our Take

The Farnsworth House is a masterpiece of minimalist LEGO architecture. Capturing the essence of Ludwig Mies van der Rohe's iconic design, this set translates the clean lines and open spaces into a striking display piece, celebrating architectural history in brick form.

This set is perfect for architecture enthusiasts and LEGO collectors seeking a sophisticated build. With a moderate piece count and focus on aesthetic accuracy, it offers an engaging building experience and a refined addition to any collection.

Skip this if you prefer action-oriented sets or value playability over display. For a more interactive experience, consider the LEGO Ideas Tree House or other sets with minifigures and play features.

Investment Grade

⏳ Appreciating

The Farnsworth House, being a retired Architecture series set, presents a potentially solid investment opportunity. Its relatively low original MSRP combined with its current significantly higher price on the secondary market indicates strong appreciation. The Architecture theme generally holds its value well, appealing to both LEGO collectors and architecture buffs. However, as with all investments, there are risks. The price trend could plateau or even decline if a similar set is released or if demand softens. The set's value is tied to its rarity and collector appeal, so maintaining its pristine condition is crucial.

📖 About This Set

Replicate a modern marvel with the famed Farnsworth House™!

Few one-room homes are as strikingly modern and instantly recognizable as the Farnsworth House™, designed by Ludwig Mies van der Rohe. This single-story steel structure with floor-to-ceiling glass walls was meant to open a minimalist interior to nature in an extreme way. Construction took place from 1945–1951 on a 60-acre estate beside the Fox River in Plano, Illinois, where it still stands today. The assembled Farnsworth House model is over 10” (25cm) wide on a base with printed name label and includes a booklet with facts about the building, its construction and history.

Architectural replica of the real-world Farnsworth House™
Booklet included with details on design and history. (English language only)
Measures over 10” (25cm) wide and 3” (7cm) tall

The Farnsworth House stands out in the Architecture series for its minimalist design and emphasis on open space. Compared to sets like the Fallingwater (21005-1), which focuses on a more complex structure integrated into nature, the Farnsworth House offers a simpler, more elegant aesthetic. While both sets appeal to architecture enthusiasts, the Farnsworth House might be preferred by those seeking a cleaner, more modern display piece. Its retired status also makes it a more exclusive and potentially valuable addition to a collection.
