Building in Haarlem
What makes Haarlem different
Haarlem combines 1930s architecture in Kleverpark and Amsterdamse Buurt with post-war terraced homes in Schalkwijk. We retain the brickwork, roof form and window rhythm while upgrading insulation, glazing and structural performance to current standards.
Active in, among others: Kleverpark, Amsterdamse Buurt, Schalkwijk, Haarlem-Noord, Zuiderhout.
Permits
Permits in Haarlem
