23 sloping bricks, including roof peak bricks, Red

Released in 1965 as part of the Legoland System era, the 980-1 set served as a specialized expansion pack designed to broaden the architectural possibilities of early LEGO house construction. During this period, the company shifted its focus toward modular play, providing supplemental sets like this one to allow builders to add pitched roofs and slopes to their existing structures, moving beyond the simple flat-topped models of the late 1950s.

The set consists of 23 iconic red plastic bricks, featuring the then-standard slope components that were integral to the aesthetic of mid-century LEGO townscapes. These pieces were manufactured during the transition toward more refined brick engineering, and their design prioritized utility, enabling builders to create classic gabled roofs that defined the suburban look of the era's sets. The collection remains a notable example of the supplementary parts packs that established the versatile design language of the modern system.
