Karlatornet Skyscraper Grasshopper Case Study

Who Else Wants a Plug-and-Play Parametric Model of the Karlatornet Tower?

Most Grasshopper downloads online are an unorganized mess of wire spaghetti that break the moment you slide a number slider.

This model was built specifically for architects, computational designers, and 3D artists who value speed, clean logic, and precision.

Why this script will transform your computational workflow:

• 100% Parametric Control: Seamlessly adjust tower height, floor-to-floor heights, rotational twist angles, and envelope geometry.

• Clean Layer & Script Structure: Every node and layer is grouped, labeled, and color-coded so you know exactly how the geometry is generated.

• Render & Diagram Ready: Export clean line work for architectural diagrams, apply materials for V-Ray/Enscape renders, or test structural loads in seconds.

• Zero Technical Friction: Designed to work right out of the box using native Grasshopper components—no obscure, out-of-date plugins required.

Upgrade your 3D assets and study real-world parametric skyscraper architecture right now.

Karlatornet (lit. 'The Karla Tower') (briefly known as Polstjärnan or Karlavagnstornet[6]) is a mixed-use skyscraper built by Serneke in Lindholmen in Gothenburg, Sweden. Started in 2019 and topped out in June 2023, the tower stands at 246 m (807 ft) tall with 74 floors, was completed in the autumn of 2024 and is the current tallest building in Sweden.[7][8]

The building's architecture firm is Skidmore, Owings and Merrill, and it was built by Serneke Group AB. It was finished in 2024, but the first inhabitants started moving in from August 2023.[10][11] The building reached 246 meters tall (807 ft), and is the tallest building in Scandinavia and in the Nordic countries. On 22 September 2022, the tower reached this milestone at 193 meters, officially surpassing Turning Torso in Malmö.
