Building sandcastles on the beach is an ancient practice that allows us to dive deep into our imagination, ideas, and dreams. For many, it was likely our first approach to construction. Water and sand merge, transforming into space—something greater than the sum of its parts. While fortresses, bridges, and moats are a thing of the past for some, another typology has emerged to take their place: the house.

Below, we present a selection of Argentine houses built on sand dunes, designed by architects who turned castles into houses, sand into concrete, and dreams into reality.

Shipping container architecture has developed its own niche in both design and representation. Colorful or grungy? Economical or gentrified? Either way, you look at it, designing with shipping containers is a serious exercise in modular planning. The physical constraints of the object make designing projects with containers a complex task, which demands specific studies in spatial organization.

The responses using this element in architecture are great and diverse, so we have selected a number of different project plans, both helpful and inspirational, that rise to the shipping container-challenge of design.

Check out selection of 10 architectural project plans using shipping containers below:
