Sentinel House is designed for flexibility. It’s the perfect venue for training courses, workshops, and seminars, with classrooms that can be adapted for small group learning or combined into a large lecture theatre for presentations and conferences. The open-plan floor space works brilliantly for hands-on training, scenario-based exercises, or even temporary storage during projects. Our boardrooms offer an ideal setting for meetings, strategy sessions, and client presentations, while our flexible office solutions give small teams or individuals a professional base for day-to-day work. The facility is built around three modern classrooms which can operate independently or be joined together to create a single large presentation space. Alongside these are three boardroom options, all offering a private, professional setting for meetings. A large open-plan floor area provides scope for more practical activities — whether that’s training, technical setup, or flexible workspace. For businesses or teams who need longer-term solutions, our flexible office spaces can be configured for hot-desking, small teams, or individual desk working. Every area has been designed to maximise usability and comfort. Sentinel House goes beyond just space — it offers a secure, professional environment tailored to modern needs. Features include: Flexible classrooms that expand into a lecture or theatre-style presentation space. Three boardrooms for executive meetings, workshops, or breakout sessions. Large open-plan floor space adaptable for training, storage, or project staging. Flexible office solutions to suit small teams or individuals. High-spec security system with 24/7 CCTV, alarms, coded access, and a secure gated yard. Excellent parking, with six designated spaces at the front door and ample free parking within 100m. Together, these amenities make Sentinel House a professional, adaptable hub for training, business, and development in Harwich and beyond.
