LEGO 508-1 Basic Building Set is a Basic theme set released in 1985, containing 66 pieces. It offers a selection of standard bricks and plates intended for open-ended construction and introductory building. Its parts features standard bricks in primary colors (e.g. 1×2, 2×2, 2×4 bricks), a few arches, several plates (2×2, 2×3, 2×4, 2×8), and two modified bricks with small wheels. Typical of the mid-1980s Basic line, the set focuses on versatile elements rather than specialized parts.

A new and sealed Basic Building Set is currently valued at around $20, with annual growth of approximately 2%, which is lower than other Basic sets. The average used price is $16 for those in good overall condition. Based on current trends, this set could be valued near $20 within the next year.

It has been a few months since we last saw 508 Basic Building Set available in either primary or secondary markets. Its true value may be slightly higher than our current estimate. The last brand new Basic Building Set was sold on eBay.

There are currently no new/sealed listings available for Basic Building Set at this time.

Insights

Released in the 1980s and now retired, Basic Building Set 508 is a small Basic-line assortment whose sealed boxes are scarce and highly condition-sensitive, and its reliance on common bricks and frequent replacement by similar assortments limits consistent collector demand.

Set Facts

The set contains multiple basic bricks in red, blue, yellow, white, and black in a variety of sizes including 1x1, 1x2, 2x2, 2x3, and 2x4. There is a special black 2x2 modified brick with red wheels and black tires, as well as a red 1x4 arch and a trans-clear 2x2 slope. The set includes a selection of red plates in sizes ranging from 2x2 up to 2x8.

About Basic

The LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.
