Renovation vs. Modernization

Renovation; refurbishment

“repair construction carried out as

a relatively large separate project.

In renovation, one may redo a

building, parts of a building,

building service technology

systems or equipment.

Renovation aims at restoring the

level a building had when it was

new.”

Modernization; rehabilitation

“repair which aims at elevating the

target's relative quality level

substantially from the original one.

In a modernisation project, the

building's energy economy can be

improved, or the building can

be linked to a sanitary network or

equipped with lifts or modern IT

techonology. Modernisation

projects can also include

procedures typical to repairs and

replacements.”

Starting point of the Leijonalinna Project


Before the renovation project, the flats did not meet

the modern requirements for housing comfort.

No major renovations had been made in the kitchens

and bathrooms. The bathrooms did not have the

damp-proofing required by today’s building

regulations, and consequently the problems were

already serious.

The electrical, plumbing and HVAC structures had

come to the end of their life cycles.

taken from the roof of the building

• The artwork was implemented by utilising digital

technology

• The mosaic tiles were manufactured by an Italian

company, CE.SI (Ceramica di Sirone)

renovation project, Architect Pasi Pohjoismäki

The Olympic Stadium Tower and the Kallio Church


Artwork


During the past few years, Kruunuasunnot Oy has

implemented more real estate decorations on

facades, stairwells and courtyards than any other

company in Finland.

Artwork increases the visibility of building and

increases housing comfort.

It also decreases vandalism and wear and thereby

maintenance costs.
