Modern Living and Shopping in the Historic Heart of Groningen

Right in the bustling center of Groningen is Herestraat 42: a project that cleverly combines modern urban planning and historic architecture. Designed by Urban Climate Architects, this building brings old and new together in a natural way, with a mix of retail space and homes.

A Smart City Project

Herestraat 42 covers three lots and borders a national monument. The ground floor retail space, with a basement, is already in full use and contributes to the city's vibrant atmosphere. Due to the tight location, an innovative construction method was used: the elevator shaft temporarily served as a tower crane. Ten new apartments are being built above the shops — quiet, bright living areas with stunning views of the city.

Timeless Design

The facade of Herestraat 42 has a classic structure with a solid base, a strong middle section and an elegant corner. This ensures that the building fits perfectly with the historic environment, while offering contemporary amenities. The design by Urban Climate Architects creates a natural connection between heritage and modern comfort.

Topping up: Efficient Urban Expansion

In a busy city like Groningen, space is scarce. That's why topping up — adding extra floors to existing buildings — is a smart way to make the city grow. At Herestraat 42, this technique is being used to build ten new apartments without additional land use. By using light and sustainable materials, the impact on the existing building remains minimal. This project shows how topping up contributes to a sustainable and future-proof city.

Herestraat 42 is an inspiring example of how history and modern architecture come together in a vibrant and sustainable cityscape.

Optoppen Herestraat Groningen: efficient urban expansion with impact

The city grows up

At Herestraat 42 in Groningen, we show how the city can grow without expanding. By topping building we are adding new homes above existing buildings.

With sustainable construction and smart design strategies, we use the city as it already exists and create space where you wouldn't immediately expect it.

Topping up as a solution for urban densification

The housing challenge requires innovative solutions. With urban densification and on top of that, we make optimal use of existing structures and infrastructure.

If building transformation architect and renovation architect Netherlands we combine topping with quality improvement and reuse.

Sustainable construction with wood and biobased solutions

Sustainable construction only really gains strength when we opt for biobased construction and smart, circular solutions. That's why we focus on timber construction: from CLT construction Netherlands upto engineered timber buildings NL.

If timber construction architect we design lightweight structures that are suitable for topping and provide minimal load on existing buildings.

Circular construction and reuse at the heart

With circular construction in the Netherlands and reuse of building materials we give existing buildings a second life.

If circular design architect we look at the use of materials and flexibility in conjunction.

Topping Groningen's housing development: sustainable densification in the city center

New homes without new land

De Herestraat in Groningen proves that the solution to the housing problem is often already there. With Top housing construction in the Netherlands we are adding homes without expanding to the countryside.

This makes topping up a powerful strategy within sustainable construction and urban development.

Transformation and topping as a combination

By transformation of an existing building combining with topping creates an integrated approach.

If renovation architect Netherlands and building transformation architect we make optimal use of the potential of existing buildings.

Timber construction and CLT as accelerators of topping

Timber construction makes lifting faster, lighter and more efficient. With CLT construction Netherlands and solid wood construction create structures that fit perfectly with existing buildings.

If architect timber construction we focus on solutions that are scalable and future-oriented.
