Between 1969 and 1976, LEGO released a range of building sets under the LEGOLAND theme that included intricate structures and scenes like the ones you mentioned. Sets such as 353 Terrace House with Car and Garage, 349 Swiss Chalet, and 369 Coast Guard Station were part of this lineup. They offered detailed models featuring buildings, vehicles, and accessories, allowing children to create realistic and immersive environments for imaginative play.
The LEGO LEGOLAND theme, introduced in the 1970s and continuing into the 1980s, comprised sets that replicated everyday scenes, vehicles, and buildings in a more simplistic style than later themes. These sets, pre-dating the minifigure era, were designed to represent various aspects of life, from towns to vehicles to castles. The LEGOLAND theme was foundational in the evolution of LEGO, bridging the gap between basic brick building and the more themed, narrative-driven sets that would become standard in subsequent years.
