13x Scenarios to consider a Building Upgrade Strategy
-
When preparing for a CAT A refurbishment, amenity upgrade or full repositioning, a strategy ensures improvements are commercially justified, technically deliverable and aligned with market expectations.
-
For buyers, an upgrade strategy provides forward-looking insight into future risks, hidden costs and essential improvements, ensuring acquisitions are accurately priced and investment ready.
-
When setting annual or multi-year capital budgets, an upgrade strategy provides clarity on priorities, helps avoid wasted spend, and ensures investment aligns with long-term asset plans.
-
When lease breaks, expiries or prolonged vacancies occur, an upgrade strategy helps reposition the space, attract stronger tenants, and align improvements with upcoming leasing opportunities.
-
As MEP, HVAC, roofs, plant or façade systems near end of life, a coordinated strategy ensures replacements are efficient, well timed and integrated, avoiding expensive reactive repairs and downtime.
-
Investors and occupiers with net zero or ESG commitments need a clear roadmap that sequences upgrades correctly, balances cost and carbon impact, and delivers measurable progress.
-
If EPC ratings are low or upcoming regulations could limit leasing activity, a structured plan is essential to identify the most cost-effective upgrades to remain compliant and protect asset value.
-
To access lower-cost lending or sustainability-linked financing, buildings often need improved ESG performance. An upgrade strategy outlines the required steps and the commercial benefits of meeting those standards.
-
Owners and asset managers planning 10 to 20 years ahead need clear visibility of future risks, system lifecycles and investment priorities to ensure assets remain competitive and resilient.
-
High energy use, poor comfort levels, maintenance issues or system failures indicate deeper performance problems that a structured upgrade plan can resolve with targeted, long-term solutions.
-
Modern occupiers demand efficient, comfortable and ESG-aligned spaces. A building upgrade strategy identifies what changes are needed to meet those expectations and retain high-quality tenants.
-
Hollen+ advises owners on how they should require capital contributions are spent, to achieve the greatest commercial benefit for the asset.
-
If rental levels, occupancy or valuation are lagging the market, targeted upgrades can enhance building quality, reposition the asset competitively, and unlock income or capital growth.
