Design collections play a vital role in the architectural process, offering a foundation for creativity and innovation. Architects use these collections to study proportions, spatial arrangements, materials, and construction techniques. They help in understanding how past designs solved problems, which can be adapted to modern needs. This also ensures that cultural and historical elements are preserved in new constructions.

Architectural design collections can be thematic, stylistic, or material-based. Thematic collections may focus on sustainability, urban planning, or residential architecture. Style-based collections highlight movements like Gothic, Bauhaus, or Brutalism. Material collections feature innovations in glass, wood, concrete, or recycled materials. Each type helps architects explore different directions in design thinking.
