Buying, selling or developing commercial real estate can be complex. To minimise risk and ensure a smooth transaction, it's essential to quickly understand an asset’s potential, along with key opportunities and risks.

We deliver clear, reliable assessments of an asset’s performance, compliance and sustainability, empowering clients to make strategic, informed decisions.

We assess the condition of buildings, infrastructure and technical systems such as HVAC, power supply and fire safety, to evaluate their functionality, efficiency and remaining lifespan – delivering a comprehensive understanding of each asset’s status.

Performance & compliance

We benchmark asset performance against market standards and sustainability goals, ensuring full compliance with local laws and codes while identifying and mitigating legal, operational and safety risks.

Sustainability focus

We identify opportunities to enhance energy efficiency, implement renewable energy solutions and align with green building certifications such as LEED or BREEAM, ensuring the asset meets sustainability goals and modern environmental standards.

Cost analysis

We project lifecycle costs, ongoing maintenance needs and modernisation priorities, providing a clear financial outlook to support informed decisions on investments, upgrades and long-term asset management strategies.

Maximise value, minimise risk

TDD is crucial for landlords, transactions and asset management as it provides a comprehensive evaluation of a property’s condition, performance and compliance. It helps identify potential risks, necessary upgrades and areas for cost optimisation, ensuring informed decisions.

For landlords, TDD mitigates unforeseen repair costs, maximises asset lifespan and enhances long-term value. In transactions, it supports accurate valuations, reduces risks and facilitates smooth negotiations. In asset management, TDD enables proactive planning for maintenance, sustainability and financial forecasting, securing the property’s future performance and regulatory compliance.
