Leierrel is once again opting for a conscious choice – Prefabricated solutions are speeding up construction in the 13th district

For the Nimród 12 Projekt Kft. apartment block development on Reitter Ferenc Street, the developer once again opted for the Leier Hungária Kft. prefabricated structural solutions. The contractor for the project in Budapest’s 13th district is S&S Wood 95 Kft., which is also part of what can be described as a well-established team, as this is already their fifth joint building.

The 16-apartment development is being built in Angyalföld, close to the Rákos stream, between Tahi út and Zsinór utca, within easy reach of shops and a doctor’s surgery.

The project incorporates a range of Leier products, from basement walls through lift shafts, staircases and balcony slabs right up to the air conditioning ceilings, which not only facilitate faster construction but also support more predictable and energy-efficient building.

The new apartment block is being built in a rapidly developing part of town

According to Tamás Sárdi, managing director of the developer Nimród 12 Projekt Kft., Sárdi Tamás, one of the key factors in selecting the site in the 13th district was the area’s development potential.

As he put it, the plot offered good value for money, whilst the new residential developments underway in the area also made the location attractive.

The project is currently at the structural completion stage, with partitioning work already underway, as well as the installation of basic mechanical and electrical systems. The project is expected to be completed in August 2027.

A fully prefabricated structural system

The building is constructed almost entirely from prefabricated elements, without the use of on-site formwork or monolithic structures.

Gábor Radnai, product manager for Leier precast reinforced concrete structures, explained that the basement level is constructed using the Leier waterproof LKF wall system, whilst the load-bearing structure utilises precast columns, beams and semi-monolithic floor panels. The superstructure is made of LKF walls and LKP climate slabs, and the building will also feature precast staircases, lift shaft elements and balcony slabs, incorporating Schöck Isokorb elements. 

The waterproof cellar walls are constructed using concrete of a quality certified by pre-test reports, and customised reinforcing steel stirrups are incorporated into the LKF walls at the wall junctions. For horizontal and vertical construction joints, the Aquaflexactiv system distributed by Bau-Haus Kft. has been installed, for which the supplier also provides a system declaration. This solution enables the construction of watertight cellar walls efficiently, quickly and with minimal labour. 

Air conditioning ceilings for energy efficiency and comfort

One of the key solutions in the project is the use of the Leier LKP air-conditioning ceiling system. The system comprises ceiling cooling and heating pipes integrated into the ceiling structure at the factory, which work in conjunction with an air-to-water heat pump system.

The advantage of this solution is that it can be operated cost-effectively even at low temperatures, whilst making use of the thermal storage capacity of the floor structure. Furthermore, thanks to factory preparation, the risk of damage to the pipes on site is also significantly reduced.

In addition to the air-to-water heat pump-based ceiling cooling and heating system mentioned above, the project will also include state-of-the-art thermal insulation and a stairwell ventilation system.

One level in two weeks

According to the product manager for the Leier, one of the greatest advantages of prefabricated technology is the significant reduction in construction time.

On the Reitter Ferenc Street project, the structural work for an entire floor is completed in an average of two weeks, whilst there is no need to plaster the walls and ceilings afterwards. The prefabricated elements also incorporate the electrical conduit and outlets.

During construction, an average of just five or six people work on each floor, which clearly demonstrates the labour efficiency of prefabricated systems.

More predictable construction, less on-site work

According to Tamás Sárdi, one of the biggest challenges facing residential property developments in Budapest today is securing a sufficient workforce of skilled professionals; for this reason, the developer has deliberately shifted its focus towards prefabricated systems.

According to the developer, one of the greatest advantages of the Leier is that it offers complete, fully functional system solutions, enabling construction to be planned precisely in terms of both time and cost.

Prefabricated technology is also more sustainable, as it generates less on-site waste, requires minimal storage space, and the components are delivered directly to the installation site. This not only speeds up the process but also enables a tidier and more resource-efficient construction process in a densely built-up urban environment.
