planquadrat with history

When Herbert Elfers, Martin Geskes and Jörg Krämer were commissioned with the "Wohnhof“ project in Mainz they founded the architectural office planquadrat over 20 years ago. Since then planquadrat has grown constantly and today employs over 100 people at both locations in Darmstadt and Frankfurt. The office has established itself and made a name for itself both nationally and internationally.
