360° Serial Renovation with ecoworks – Fast. Cost-effective. Scalable.
ecoworks is your general contractor for serial and sustainable building modernization. Through digital planning and industrial prefabrication, we deliver energy-efficient renovations that are not only fast and cost-effective but also proven to succeed. Together with our clients and partners, we develop future-ready solutions that drive innovation, economic success and climate protection in the building sector.
How Serial Renovation Works at ecoworks
With serial renovation, we bring digitalization and industrialization to residential buildings. Our prefabricated façade elements come equipped with insulation, windows, thermal protection, and ventilation systems all installed at the factory. When needed, new utility lines can be routed along the exterior. This approach shortens construction times, minimizes disruptions, and delivers higher quality making modernization more cost-effective and climate-friendly.
If desired, we can deliver NetZero standards. Buildings generate their own energy for heating, hot water, and electricity thanks to rooftop solar panels. Serial renovation also makes it possible to expand living space for example by adding balconies or building upward up to nine full stories.

Facade Elements
Our facade elements come factory-equipped with insulation, windows, thermal protection, and ventilation systems. New lines for heating, cold and hot water, circulation, and electricity can also be easily routed along the exterior.

Energy Supply
We can renew the heat generation of the building to be renovated at a low temperature and therefore sustainably and, upon request, establish NetZero operation. The energy required for heating, hot water and household electricity is then generated by the building itself.

Basement Insulation
To further reduce energy loss, we efficiently and sustainably insulate the basement ceiling. This keeps more warmth inside the building and noticeably lowers energy costs.

Roof Elements
Our industrially prefabricated roof elements allow for fast roof renovations and easy integration of solar panels. Using our proprietary methods and modules, we renew roofs in a cost-effective and climate-friendly way.With manufactured roof elements, we replace the roof and cover the roof areas with photovoltaic modules.

Living Space Expansion
Serial renovation not only preserves existing living space but also creates new areas through densification. Through our partners, we add rooftop extensions of up to four full stories, as well as convert attics and add loggias.

Balconies
Freestanding balcony systems offer greater living comfort and flexibility as multifunctional building elements. They provide additional outdoor space that can be used as an open-air living room, storage area, or even a garden substitute.Upright balcony systems can be planned and installed quickly and easily to create new living space.

Frequently Asked Questions
Serial renovation is a modern method for quickly and cost-effectively upgrading existing buildings. Prefabricated façade, roof, and technical modules are produced in factories and then mounted directly onto the building. These modules already include insulation, windows, thermal protection, and ventilation systems, which shortens construction time and improves quality. Serial renovation significantly increases energy efficiency and climate performance, often using renewable heating systems and even achieving a net zero standard. It can also create additional living space, for example through new balconies or additional stories on top of existing buildings.
Our approach is particularly well suited for apartment buildings from the 1950s to the 1980s with three to five floors. The method works best for buildings with simple, repetitive shapes without complex bays, recesses, or curves. Repetitive layouts and identical window openings across floors allow for maximum standardization of façade elements. Entire neighborhoods with homogeneous structures offer the ideal conditions to scale projects efficiently and reduce per-unit costs.
From an energy perspective, buildings with low ratings (G–H, in some cases D–F) are especially good candidates, because they can be upgraded to climate-friendly standards in an economical and efficient way.
Yes. One of the biggest benefits of our approach is that serial renovation can be carried out while tenants remain in their homes.
Thanks to the high degree of prefabrication and the focus on the building envelope, work inside apartments is kept to an absolute minimum. In many cases, units don’t need to be entered at all, or only briefly for specific tasks. A key reason is that supply lines (via the technical module) are run along the façade, avoiding the usual weeks of disruptive work inside occupied apartments.
As a result, noise, dust, and construction-related disturbances are much lower than with traditional renovation. Most noisy, dust-heavy work takes place in the factory, and the short installation time on-site further reduces disruption.
Yes. Creating additional living space is a strategic component of the ecoworks model. This transforms renovation from a pure cost factor into a value-generating investment.
- Vertical extensions: In partnership with timber modular construction companies, it is possible to add up to four full additional floors, creating entirely new and attractive housing units.
- Other extensions: The offering also includes new, elevated balconies, converting unused attic space, and transforming spaces into loggias.
Living space expansion is a major economic lever for renovation projects. While energy upgrades reduce future energy and CO2-related costs and preserve property value, adding new apartments generates direct and sustainable rental income. This additional revenue significantly shortens the payback period and improves financing options.
Upgrading the building envelope can reduce energy demand by up to 83%. On average, annual heating costs per apartment are lowered by around €500, which helps keep overall housing costs stable despite the modernization.
It’s important to distinguish between the overall project duration and the actual on-site construction time. From the first analysis through detailed planning, production, and final completion, the whole process can take up to a year.
The real advantage of serial renovation is the dramatically shorter time spent on-site. Installing prefabricated façade and roof elements along with new building systems typically takes just a few weeks. By shifting much of the work to the factory, the on-site construction time can be reduced by 30 to 70 percent.
Federal, state, and local programs offer various funding options, often linked to rent regulations or social housing quotas. On the federal level, subsidized loans and repayment grants are available (for example, KfW 261), alongside the federal "BEG" program, which offers a special serial renovation bonus (from Efficiency House 55 level). Using prefabricated façade or roof modules qualifies for a 15% bonus on eligible renovation costs. This can be combined with additional bonuses, such as the Renewable Energy Class (EE), Sustainability Class (NH), or the bonus for renovating a "Worst Performing Building" (WPB). In total, subsidies can cover up to 45% of eligible costs in the form of repayment grants.
As a turnkey provider, ecoworks supports clients in navigating and applying for these complex funding programs.
Modern building systems require regular professional maintenance to ensure durability, efficiency, and warranty protection. This applies especially to the heat pump, photovoltaic system, and decentralized ventilation units.
A unique advantage of the ecoworks approach is easier maintenance access. By placing utility lines within the façade, most work can be carried out from outside, avoiding the need to enter apartments. This minimizes inconvenience for tenants.
