Why have we brought our collective Sidara firms in the UK together in one building?

As a group of companies, Engineering News Record (ENR) ranked Sidara (formerly Dar Group) #10 of the top 225 international design firms and at or near the top in most sectors of design and engineering. So 150 Holborn presented a unique opportunity to bring all our respective member firms in the UK together in one collaborative space and work together, harnessing the power of our combined skills, knowledge, and expertise to deliver truly innovative and turnkey solutions to the world’s most challenging and exciting projects.

 

 

150 Holborn provides a vibrant and generous addition to the Midtown Holborn townscape, improving public spaces surrounding the building, and respecting the area’s historic character.

As a showcase for Sidara’s expertise, 150 Holborn offers:

• planning, architecture, engineering, sustainability, energy, cost consultancy, project management, building surveying and a range of specialist advisory services

• a BREEAM design stage rating of Outstanding, achieved by less than 1% of new buildings

LEED Platinum design stage rating

• productivity and wellbeing supported through technology, data driven design, and the building’s SMART technology

• the flexibility to adapt to change

• performance in use monitored continually to improve operational and energy efficiencies

Sidara member companies now at 150 Holborn: Currie & Brown, Dar, Introba, Maffeis Engineering, PARA, Penspen, Perkins&Will, Portland Design, TYLin, Urban Initiatives.

 

Having acquired 150 Holborn in April 2015, we explored various development options via a feasibility study before concluding that a new build would be the optimum solution. Work began on site in June 2019, with the demolition of the old building. Following a topping out ceremony in September 2021, completion was achieved in December 2022 and our individual member firms moved in between January and March 2023.
