The team of Kaamos Construction), part of the Kaamos Group, benefit from 15 years of experience in building quality homes suited to the Estonian climate.

We employ professionally certified engineers and hold Lloyd’s Register Quality Assurance certificates ISO 9001-2015 and ISO 14001-2015 as well as licenses pertaining to construction.

To preserve the building’s history and style, as much of the original finishing and details of the Gonsiori 29 building as possible are maintained during its reconstruction into an apartment building.

All original loadbearing structures are preserved. These are carefully assessed to identify their state and if necessary, reinforcement works are done.

To build apartments with modern commodities, all the building’s plumbing systems are completely changed.

Finishing repair works are done on the building’s facade to maintain its original image and details. The aim is also to restore the original hallways of the building.

Grand Gonsior will be completed in spring 2019.

Construction structures

Foundation. During the renovation, the slate foundations and basement walls rendered inside and outside, are preserved.

Exterior walls. The massive exterior walls of the building are made of bricks and the thickness of the walls can be even up to 77 cm. The original facade finished with Terrasit rendering is preserved and renewed. The courtyard side facade of the building is covered with new finishing.

Roof. The roof structure is made up from a tin-covered hip roof leaning on timber rafters and scantling, which are also preserved and renovated.

Interior walls. Inside the building, the massive brick walls with thickness up to 64 cm are preserved. In addition to the existing brick walls, composite walls (masonry + plaster) are used for the walls between the apartments to increase sound insulation of the structures. The added new walls between the rooms are metal-framed walls with plasterboard covers.

Floors. The existing floors are preserved. Their sound insulation is improved by added levelling and sound insulation layers.

Halls. The original stairways and railings are reconstructed or, if necessary, replaced with new ones suitable with the 1950s style. All three halls of the building also have an elevator.

Windows. All existing windows are replaced with new, two-framed, triple pane wood-aluminium windows. The courtyard side windows of the building will be cut larger to bring more light in the rooms.

Doors. The front doors of the building are equipped with video entry-phones. The apartment front doors are veneered rebated flush doors. The doors inside the apartments are 2.3 m high white profiled doors.

Interior finishing. The lobby and the halls will get a new and grand look. The apartments are finished according to the client’s wish, either with the products selected by the client or a package prepared by an interior designer. More information on the interior finishing packages is available here. The living rooms have parquet floors. Hallways, toilets and bathrooms, and laundry rooms have ceramic tile floors. The bathroom walls are covered with ceramic tiles and moisture-proof dye. The living room walls are also painted and one wall of the master bedroom is covered with tapestry.



Plumbing. The bathrooms have a sink, wall-mounted toilet and a stone bath with tap or a float glass shower stall. In all apartments, there is a washing machine readiness either in the bathroom or in the laundry room. It is also possible to install a dryer in every apartment. The larger apartments have an additional separate WC.

Heating. Grand Gonsiori residence is connected to the district heating system of Tallinna Küte. The building’s heating system is completely renovated. During the reconstruction works, the heating plumbing and heating elements are changed. Cast iron radiators are in all apartments and public spaces. The radiators are controlled using thermostats. Electrical floor heating is available in the bathrooms for convenience.

Ventilation. Central ventilation with mechanical heat recovery is planned for the apartment building. A separate air discharge pipe is planned for the kitchen exhaust hood through which the discharged air is directed to the roof.

Water and sewerage. Hot water is produced based on the district heating in the heating room of the building. Remotely read water meters for hot and cold water are installed behind the suspended ceiling (in the hall, bathroom or laundry room).

Strong and weak current. Electrical floor heating installed in the bathrooms can be adjusted via thermostat mounted on the wall. All rooms have power outlets and switches. Data and TV outlets are installed in the living rooms. The apartments are ready for installing security alarm systems. To ensure fast data connection, an optical cable is installed between the building’s main data switchboard to the apartment’s switchboard. Recessed lights are installed in the drop ceilings in hall, bathrooms and laundry rooms. Schneider Renova collection switches and outlets with classical design are used in the apartments.

Storage rooms. A storage room at the basement level comes with each apartment. The storage rooms have light wood-structure walls covered with unfinished plywood.

Parking. The residents can buy a parking spot in the fenced courtyard.

Extended three-year construction warranty is given to the reconstructed building.
