From its beginnings, Jaureguizar has specialised in the development of social housing projects. Currently they undertake the whole real estate process for dwellings, whether free market or socially protected ones, office buildings, retail centres, car parks and industrial estates. Its innovative mission gave rise to the creation, together with Tekniker, of the domotics company Dinitel.

Jaureguizar has been a collaborating organization of Tekniker since 2005.
