The modern office is shrinking, not in ambition, but in footprint. Hybrid working, smaller teams, and a push for quality over quantity have created new demand for compact, collaboration-ready workspaces. For landlords holding oversized, underutilised office floors, this shift presents a real opportunity - if delivered correctly.
10 Benefits of Subdividing Large Office Spaces
Higher Yield per Square Metre: Smaller, flexible units often command higher rental rates proportionally than full-floor leases.
More Diverse Tenant Mix: Start-ups, embassies, consultancies, and SMEs all seek ready-to-go, right-sized spaces.
Reduced Void Risk: One vacancy in a multi-tenant building poses less financial risk than losing a single full-floor occupier.
Faster Lettings: Plug-and-play offices allow tenants to move in quicker, reducing downtime.
Future-Proofed Assets: Offices designed for hybrid work are more attractive in the long term.
Operational Flexibility: Landlords can reconfigure or re-let smaller spaces with more agility.
Improved Building Efficiency: Tailored M&E systems serve individual units more effectively.
Increased Capital Value: Higher occupancy rates and improved rent rolls enhance asset valuation.
Tenant Retention: Quality spaces that support modern working are more likely to retain occupants.
Stronger Market Positioning: Adapted properties stand out in a competitive commercial landscape.
10 Challenges You’ll Need to Overcome
Live Environment Constraints: Tenants still in place mean minimal noise, dust, or disruption.
Maintaining Operational Services: BMS, HVAC, and electrical must remain live during works.
Limited Access and Storage: Urban sites often lack skip space or delivery bays.
Precise Logistics Planning: Just-in-time delivery becomes essential when storage is off the table.
Complex Service Separation: M&E systems must be split without affecting active tenants.
Night and Weekend Works: Noisy activities must often be scheduled out of hours.
Tight Timelines: Programmes are short and highly coordinated.
Regulatory Compliance: Floorplate changes must meet current fire, access, and building regulations.
Sensitive Stakeholders: Diplomats, childcare providers, and retail-facing tenants all have unique needs.
Design Consistency: High-spec finishes and compliance must be maintained across every new tenancy.
The Donnybrook House case study shows this approach in action. Subdivision and technical upgrades were delivered in a live, fully tenanted building with no disruption to operations. Built managed the entire transition - from mechanical separation to bespoke tenant fit-outs, unlocking new income and long-term flexibility for the asset owner. Real challenges, real results, and a model that’s already being repeated.
