AK Modular designs and manufactures permanent modular homes, combining custom residential projects with a more standardized Express product line. The construction approach uses industrialized structural production to prepare major building components before site assembly.

Buyers can define the house around their plot and program or select a faster model-led route where suitable. With production operations in Vitoria-Gasteiz and Coria, the company is relevant to clients seeking a Spanish manufacturer that can handle both individual architecture and repeatable housing solutions.
