Renovation engineering for heritage buildings

The restoration of heritage buildings demands a deep understanding of architectural history, meticulous architectural and structural engineering, and specialised expertise in integrating traditional and modern solutions.

We ensure your building receives a new lease of life worthy of its value. We are among the most experienced renovation engineering specialists in Finland, particularly in the restoration of listed and protected buildings. Our projects are characterised by close collaboration with property owners, heritage authorities, and end users.

"We provide modern solutions without compromising the building’s historical character and atmosphere."

Restoring historic value

When working with historic buildings, the objective is invariably conservation-led renovation. Architectural features such as façade plaster ornaments, roof structures, windows, corridors and stairwells should be preserved without altering their original appearance.

In heritage properties, original materials also hold intrinsic value. Elements are only replaced if they are so damaged that repair is no longer viable. In restoration work, we also strive to reinstate the building’s original colour scheme.

Our experienced renovation engineering experts are skilled in restoring the original character and architectural splendour of your heritage building. Through building history investigations and colour studies, we identify original surface materials and construction techniques. The building’s repair history and condition surveys provide insight into the structures' current state and guide appropriate restoration methods.

Understanding modern needs in builiding restoration

Planning repairs for heritage buildings requires a careful balance between today’s functional needs and the cultural and historical value of the existing structure. Protected historic buildings often cannot fully comply with modern building physics standards, for instance, it is rarely possible to achieve the same energy performance levels as in new constructions.

Nevertheless, our goal is to identify effective ways to improve the energy efficiency of your heritage building. During renovation, modern building services can be integrated without compromising the building’s historical character and atmosphere.

Integrating the old and the new

To successfully integrate new structures into an existing property, we use detailed surveys and building information modelling (BIM). We digitally document the building using photogrammetry, 3D scanning and laser scanning, allowing us to create an accurate digital model. This significantly facilitates both renovation and future maintenance.

The BIM model includes detailed information on the building’s structures and materials. In addition to supporting design and maintenance, it plays an important role in documenting culturally and historically significant buildings, for example, in case of fire or other damage.
