LEGO 283 Red Sloping Ridge and Valley Bricks is a System i Leg supplementary set released in 1957 as part of LEGO’s early Roof Brick Assortment series (sets 281–284). It contains approximately 20 red roof elements, a mix of convex, concave, inverted, and corner slopes in 2×1 and 2×2 formats.
These specialized pieces were among the first LEGO roof components ever produced, designed to bring greater architectural realism to LEGO houses within the Town Plan system. Builders could create pitched roofs, ridges, and valleys to mimic real construction techniques, marking an early milestone in the evolution of LEGO’s “System of Play.” The set was sold in a small cardboard parts box bearing the classic red-and-white LEGO Mursten logo, and remained available through the early 1960s in several European markets.
A new and sealed Red Sloping Ridge and Valley Bricks is currently valued at around $29, with annual growth of approximately 4%, which is lower than other Supplemental sets. The average used price is $17 for those in good overall condition. Based on current trends, this set could be valued near $30 within the next year.
