Our portfolio is continuously being developed with our customer’s needs in mind.

The Building

The Marq’s exquisite artwork draws you in as you are greeted by a dynamic double-height entrance, and an Italian marbled floor that wraps up the wall, creating a sense of movement.

With flexible, column free floors and an abundance of natural light, all floors enjoy a corner aspect overlooking Jermyn Street, and floors 4 and 6 have a terrace. The customer facilities on the lower basement include cycle parking, private showers and changing rooms, all designed with wellness in mind.

Access to daylight supports natural circadian rhythms and healthy sleep. The Marq has been designed with full height glazing to ensure that every floor enjoys good levels of natural daylight.
WELL Certified buildings make it easier for employees to build healthy activities into their daily routines. The Marq has 54 cycle spaces and the shower facilities are excellent, with five male and four female showers.
Noise can be an unwelcome distraction at work. It’s stressful and damages productivity. We have installed high-performance double-glazing throughout The Marq, and taken measures to reduce mechanical noise and vibration.
We all feel healthier and more alert in well-ventilated spaces. We have invested in materials and filtration to achieve excellent indoor air quality at The Marq. The fresh air supply rate to the offices is 50% above minimum recommended levels.
The Marq’s two terraces, on the 4th and 6th floors, will be green, calm and relaxing areas. These outdoor spaces will incorporate landscaping amongst fixed seating.
We have found ways to put people in charge of their own thermal comfort without the need to adjust the overall room or building temperature, for example, we are installing blinds on all windows.
Even low levels of dehydration can affect cognitive performance. We’ve ensured that all water supplied to amenity areas, toilets and other facilities is potable so everyone can access drinking water when and where they need it.

Architecture & Design

The Marq delivers contemporary new landmark office building to St James’s with a striking double frontage and uncompromising design features throughout.

The Marq has been designed and crafted with attention to every detail. Finished in the highest quality Portland stone and brick, it moves the architectural language of St James’s forward, with eloquence and sensitivity.

The artwork takes you on a journey that flows from the street into the building, embracing and welcoming customers and their visitors.
