Mace has completed The JJ Mack Building office development near Farringdon station.

The 200,000 sq ft scheme by Helical plc and Ashby Capital at 33 Charterhouse Street offers 10 floors of technology-enhanced office space including three terraces and extensive views across central London.

Incorporating smart building technologies and various measures to enhance its sustainability, the building is an example of a forward-thinking building design. All working environments can be operated and controlled via a dedicated app, allowing building users to control heating, cooling and lighting, and monitor energy usage and occupancy levels to minimise the building's environmental impact.

A 3D ‘digital twin', powered by data collected from building sensors, drives its systems to adapt and provide an optimal environment for occupiers, monitoring air quality and CO2 levels.

The development will have an A-rated Energy Performance Certificate (EPC), a BREEAM "Outstanding" rating (the first building in the UK to achieve this rating at the design stage), and a 5-star NABERS rating for its commitment to sustainable operations and energy performance.

The carbon emissions during construction were kept to a minimum through low carbon materials such as ‘Earth Friendly Concrete' and sustainable design measures such as a connection to Citigen's district energy network which provides energy from renewable sources.

A real-time weather-linked dynamic water management system recycles much of the building's collected water and adjusts its capacity in response to anticipated rainfall. 144 photovoltaic solar panels that generate energy that is fed back into the grid help the JJ Mack Building offset some of its energy use. A green roof covering 885 square meters houses two bee colonies and various plant and animal species to encourage biodiversity.

Ged Simmonds, MD Commercial Offices and Residential at Mace, commented: "We're delighted to have delivered a building that raises the bar, both for sustainability and as a smart working environment. It's been a fantastic journey working with Helical's team and I'm proud of our team's contribution to a development that sets a positive example of what can be achieved to create smart and healthy working environments for the future."

Pavlos Clifton, Senior Development Executive, Helical plc, added: "Working with our trusted partners in the consultant and construction fields is the cornerstone to the successful delivery of all our projects. The JJ Mack Building has been Mace's third opportunity to demonstrate their commitment to achieving our vision and I could not be happier with the result. The successful delivery, on time and on budget, of this best-in-class building through what can only be described as "exceptional circumstances" is a credit to them. The JJ Mack Building is a testament to the resilience and professionalism of the whole construction industry."

Three retail units and ten office floors from 13,150 to 27,500 sq ft are available through Knight Frank and CBRE.
