The Property Context
8th December, 2025
LEASES, LANDLORDS & PORTFOLIO RIGHTSIZING
The commercial real estate sector is undergoing a profound structural transformation driven by the permanent entrenchment of hybrid working patterns.
The data proves that office space demand from 2019 – 2023 fell by a staggering 41% for companies expecting staff in the office only one day per week but grew by 1% for businesses maintaining a four to-five-day attendance expectation. This bifurcation in demand is reshaping portfolio strategies globally. For instance, the total value of annualised revenue for in-force office leases in the United States declined by 15% from 2019 – 2023. Within the United Kingdom the market is experiencing an aggressive flight to quality where newer buildings with premium amenities fare significantly better than lower quality commodity spaces.
Prime rents are demonstrating remarkable resilience and growth across regional UK hubs as businesses compete for the best future proofed spaces. Bristol currently leads the UK regional markets with a prime rent of £50 per sq ft driven by strong demand from financial services and tech occupiers. Reading commands £56 per sq ft while Birmingham prime rents rose to £46 in 2025 and are projected to reach £48 in 2026.
The legislative environment is also tightening considerably. On 1 April 2026 the UK government will implement a comprehensive business rates revaluation alongside a new five-tier multiplier system. This legislation introduces a high value multiplier of 50.8p for properties with a rateable value of £500,000 and above. The cost of inaction is severe. Occupying inefficient legacy spaces exposes businesses to escalating tax burdens and declining asset relevance. Business leaders must view their property context not as a static operational cost but as a dynamic financial lever that requires constant calibration.
THE MARIS METHODOLOGY:
We do not treat property selection as a standard real estate transaction; we treat it as an exact science. We engage with our clients during the feasibility phase, long before any Heads of Terms are signed, to hunt for the “ghosts in the machine” – the invisible constraints that will cost you money later.
Our assessment executes a strict validation protocol:
Step 1: Mechanical Capacity Validation
We test the physical limits of the building. If the base-build HVAC cannot genuinely deliver the BCO’s recommended 12 – 14 litres of fresh air per second per person, your high-density hybrid workforce will be drowsy by 2:00 PM. If it fails, we negotiate landlord capital contributions to fix it before you sign.
Step 2: The Structural Stress-Test
We verify the column grid and window mullion spacing. If the window mullions are not set to a standard 1.5m planning grid, every single meeting room partition you build will require highly expensive, bespoke glazing.
Step 3: The Licence to Alter Timeline
Most UK commercial leases prohibit alterations without written landlord consent. We map this 4-8 week legal approval window directly into our master delivery programme to prevent your rent free period from evaporating while you wait for a signature.
THE CFO’S CORNER:
The property context in 2026 requires balancing strict cost control with the absolute necessity of occupying premium space. The introduction of the 50.8p high-value multiplier in April 2026 means that holding excess square footage in premium locations is a severe financial liability. CFOs must therefore focus aggressively on rightsizing. This strategy involves identifying dead zones within the current floorplate and leveraging that data to downsize the overall footprint while simultaneously upgrading the quality of the remaining space.
We are also advising financial leaders to explore the managed office sector as a transitionary tool. Managed office supply has increased by an astonishing 895% since 2019 providing self-contained floors with private amenities on flexible 12 – 48 month terms. This offers a compelling alternative to traditional 10 year leases by removing the massive capital expenditure of a bespoke fit-out while still delivering a branded premium environment. We work directly with financial teams to code invoices correctly so that these capital allowances effectively subsidise the cost of mechanical upgrades ensuring the CFO can fund a high-performance workplace without compromising the corporate balance sheet.

MARIS TOOLS:
- The Stay vs. Go Scorecard
A quantitative framework evaluating location access, capacity infrastructure and landlord flexibility. Determines if renewing a current lease yields a higher return on investment than relocating. - The Asset Health Check
A physical audit assessing peak occupancy requirements against mechanical capabilities such as fresh air supply and digital connectivity ensuring the building can support hybrid density. - Lifecycle Cost Model
A financial forecasting tool that maps the true total cost of occupation over the lease term.
