Basler Kantonalbank

Basler Kantonalbank is the cantonal bank of Basel-Stadt and serves private customers as well as businesses and investment clients. The construction loan belongs to the bank's own product line, so advice relates to its in-house offering rather than a selection of outside lenders. Requirements include an architect's contract along with the same collateral and equity as a regular mortgage; there is no fixed minimum amount, and there is no amortization obligation during the building phase.

For follow-up financing, the bank offers several mortgage models, including fixed-rate mortgages with various terms, the SARON mortgage, a variable-rate mortgage and a sustainability mortgage. The website is available in German and English, and an advisory appointment can be booked online.
