Overview
Enterprise Suites

Northumberland House has been thoughtfully refurbished for modern working, combining bright, well-proportioned office floors with high-quality finishes and space for different ways of working.

Fitted desks, private meeting rooms and focus booths give teams a balance of shared working space and somewhere to concentrate. Dedicated kitchens support the everyday, while lounge space offers room to step away or catch up. High-speed WiFi and unit-level climate control keep things comfortable and connected, with 24-hour access allowing businesses to set their own rhythm.

Behind the scenes, the operational essentials are taken care of. Daily cleaning, facilities management and reactive maintenance keep the building running smoothly, while business rates management, simplified billing and statutory Health & Safety compliance help to reduce unnecessary admin. Snacks and consumables add a little everyday convenience.

Showers and changing facilities make it easier to freshen up before the working day, while disabled access and a dog-friendly approach support a welcoming environment.
