Scottish Power’s St. Vincent Street headquarters in Glasgow is a significant addition to the city’s skyline, marking the largest single-use office construction in the past 25 years. This fourteen-storey building has been strategically designed to maximize its efficiency and adaptability for the future. Its architectural concept comprises two linear east/west office blocks with varying floor plate heights, connected by a top-lit glazed atrium and service cores.

This building has not only transformed a previously derelict site but has also enhanced the city’s appearance, particularly from the motorway. It now stands as a prominent feature in Glasgow’s skyline, offering a safe walkway for pedestrians, protecting them from the unpredictable Scottish weather, and optimizing floor space on the upper levels.

Sustainability

Efforts to reduce energy consumption were embedded in the design from the beginning. The decision to use concrete as the primary building material was a key energy-efficient choice. The concrete’s thermal mass allows it to absorb and release heat, contributing to temperature regulation. The design of the southern elevation incorporates external ventilation risers and a high-performance glazing system to minimize solar gain. The building’s ventilation system includes heat recovery, and a sophisticated Building Management System (BMS) ensures effective control of mechanical systems and lighting.

Sustainability is a core principle of this building’s design. Rainwater harvesting minimizes water consumption, and the building achieved a BREEAM rating of excellent and a minimum EPC of C.

Brief

Extensive engagement with staff guided the design process. The building aims to enhance the well-being of its occupants, offering amenities like a restaurant, gym, and occupational health suite. These facilities are strategically located within the building, ensuring ease of access and visibility.

The interior layout was thoughtfully designed to meet various parameters:

• Modularity: Spaces are organized according to a ceiling grid module, allowing for easy interchangeability.
• Noise Control: Special attention was given to reducing noise transmission between enclosed areas.
• Work Settings Variety: The modular spaces create individual workspaces, collaborative areas, and support spaces, providing flexibility for employees. Informal meeting areas break the rhythm of workstations.
• Daylight and Views: Enclosed spaces are positioned along the atrium facade, allowing natural light and city views to permeate the floorplate.
• Proximity to Services: Wet areas are strategically located near building cores for efficient access to mechanical and electrical services.
