Architectural solution

The area to be built up is situated on the border of the city centre, between Järvevana tee and Pärnu mnt, on the former territory of the dairy industry Tere AS (formerly known as Tallinna Piimatööstus). The two tower blocks, the business premises at Lelle 22 and the office-residential building at Lelle 24, are interconnected by a gallery located in the plane of the second storey [the ground floor counts as the first storey], on which a resting zone and children’s playgrounds have been planned, and an underground two-storey car park.

The designed tower block is located deeper inside the lot compared to other buildings drawn up in the detailed plan, thus it is further away from the noisy Järvevana tee. The main volume of the tower block is a cuboid stretching from the north-east to the south-west. Thanks to this orientation, good lighting conditions are guaranteed in all rooms of the building drawn up in the plan, whether residential or office.
The lower, two-storey volume stretches toward Pärnu mnt up to the border of the property. The plane of the second storey of the building is connected to the second storey of the building at Lelle 22 over the street passing through the parking building, thus creating an ensemble of buildings located on two properties.

The requirements of the detailed plan have been followed in the placement of the building on the lot. At the same time, the possibility to build two additional tower blocks on the lot in the future has been retained.
Lelle 22 is a 14-storey office block. The facade of the office block has been designed to consist of two parts – the slanting facade open towards Järvevana tee and the facades adjoining it have been planned as structural glass walls. The other facades of the building are covered with composite plates, thus forming an integrated whole with the residential-office building at Lelle 24.

Lelle 24 is a 16-storey office and residential block. The residential-office block has been designed with a view to harmonising it with the environment and the urban context planned for the area.
The ground floor of the residential-office block is intended for office space and a presentable vestibule with two entrances. The storeys from the second to the ninth are planned for office space. However, the storeys from the tenth to the top one are intended for apartments, including luxurious apartments with spacious terraces on the last two storeys.

Traffic arrangement

Two new areas for traffic will be partly constructed pursuant to the detailed plan: Lelle Street and Piima Street. Lelle Street will be built between Pärnu mnt and Kohila Street (with an exit to Järvevana tee) and Piima Street between Pärnu mnt and Lelle Street. A junction with traffic lights will be built at the intersection of Piima St and Pärnu mnt.
In the current implementation phase of the detailed plan, the section of Lelle Street up to the plot of Lelle 24 (included) and the section of Piima Street up to the plot of Piima 4 (included) will be built. The aforementioned streets will be linked with a traffic area running below Lelle 24 and the parking house (Piima 4) that is constructed in the same construction stage.

The architect of the buildings is Ignar Fjuk.

The energy efficiency class of the buildings is B.

Frame of the building

The structural frame of the apartment building consists mainly of precast reinforced concrete elements. Three-layered panels with 150 mm of insulation in between form the external wall.
The external walls will be covered with composite plates.
The floors are made of 265 mm thick prefabricated hollow-core slabs, the sound insulation layer is formed of polystyrene foam that is 50 mm thick, on top of which a concrete screed layer of 50–70 mm is cast.
The load-bearing internal walls are made of 180 mm thick reinforced concrete panels. The non-load bearing walls between the apartments are made of Aeroc blocks (Classic or Element line) 150 mm / clearance 20 mm / mineral wool 30 mm / Aeroc 100 mm.
The partition walls within the apartments are made of double plasterboards on a metal structure, the infilling is mineral wool (66 mm).


The roof construction consists of hollow-core slabs (265 mm), which will be covered with a vapour barrier; the insulation is 250 mm thick and the roofing on top will be of styrene-butadiene-styrene (SBS).


The stairs inside the buildings are made of precast reinforced concrete and covered with a dust barrier.
