Effectively refurbishing residential portfolios

Secure property values – Prevent stranded assets


For some years now, it has been clear that climate change is progressing much faster than predicted. For this reason, the real estate industry, together with politicians and society, must take ambitious action to reduce CO2 emissions and decarbonize all areas of life.

The challenge: Climate change meets refurbishment backlog  

The building stock is an important key to success here. At the same time, property owners and investors have a considerable task ahead of them. After all, existing buildings are responsible for a significant proportion of climate-impacting emissions.

The EU is currently tightening the regulatory framework as part of its taxonomy and ESG requirements. Failure to act will therefore become expensive in the quite near future. This applies in particular to large residential property portfolios that have not yet been upgraded in terms of energy efficiency. They risk becoming stranded assets.

Are you also these facing challenges for your residential property portfolio?

  • Aligning your own residential assets economically and energy-efficiently for the future
  • Acting in view of the increasing climate protection and sustainability regulations
  • Quickly refurbishing large properties, both occupied and unoccupied
  • Proceeding strategically despite unclear structural and technical parameters of very different properties within a portfolio
  • Utilizing unused land potential meaningfully, keyword redensification
  • Creating a livable, sustainable, and affordable living space for people to live together
  • Leading projects to the finish line despite a shortage of skilled labor and material bottlenecks
  • Meaningfully integrating digitalization in buildings and in asset and portfolio management
  • Finding the right funding and utilizing it for your project and portfolio


Effectively refurbishing residential portfolios – the right processing model is crucial

Drees & Sommer offers comprehensive strategies for refurbishing residential building portfolios. The focus is on improving the energy balance, exploiting the potential for redensification, and promoting coexistence in the property and neighborhood.

Our solution is to adopt the right processing model, whether serial, conventional, or a mix of both, so that we can manage all types of refurbishment. The right strategy saves costs and gets projects moving faster.

The Drees & Sommer team starts with technical due diligence (TDD), sets out the CAPEX measures, and carries out a detailed potential analysis. Among other things, it deals with a pre-check of the energy balance, the potential for redensification, building law, and the right subsidies.

In the design phase, a decision is made on the right processing and implementation concept. This is followed by the technical feasibility concept with profitability analysis, a framework schedule, and ESG schedule.  

During implementation, Drees & Sommer supports you with services such as general planning, project management including cost and schedule control, and successive subsidy management. In addition, thanks to our comprehensive reporting, you are always up to date with the latest construction progress.
