The Leier show house in Szentendre will be a real show of strength

Szentendre is the first city in Hungary to have created the ÉMI (Építésügyi Minőségellenőrző Nonprofit Kft.) National Model House Park, which demonstrates how we can build sustainably today. One of the most important objectives of the Park is to promote energy-conscious and environmentally friendly attitudes: to present technical solutions and innovations that meet the requirements of energy efficiency and sustainability to a high professional standard on a central platform - for both the general public and professionals.

The Leier show house will also be built in this park, which will serve as an example for families planning to build with its forward-looking architectural and engineering solutions.

The house takes shape

We have previously reported on the structural solutions of the Leier model house structural solutions. In our current article, we can show not only the significant progress made in construction in recent months, but also how flexibly the various parties involved in the construction can work together to achieve the best possible results.

Since our last report, many of the building's components have been replaced, including

• a Leier roof tiles, chimney and partition walls;
• Hofstädter windows and doors - the building can now be locked and heated by the installation of front windows;
• Roto roof windows;
• DELTA®-MAXX POLAR roof insulation; in fact,
• the sub-base concrete layer system is also complete: the 8 cm thick Austrotherm thermal insulation layer with heat reflective foil, spacer mesh, and Wavin Magyarország heating pipes supplied by the
• the interior walls have also been machine-plastered.

Almost all Leier products are now in place

Architect Zsuzsanna Parádi informed us about the further phases of the work. The project is progressing as planned, she said.

"Depending on the weather, the final finishing of the façade, the installation of the Hella shading and the installation of the tin elements, the colour of the façade using the Baumit materials will start in the next few days."

"We are trying to demonstrate the versatility of concrete," he added, "with unusual solutions on our house, such as interior thermal insulation, structured surface wall construction, cooling and heating wall and slab surfaces as part of the mechanical system, and exposed concrete interior and exterior elements." Over the past months, following the construction of the structure, additional Leier products have been added to the building, so that today the building can showcase an outstanding range of products to the public. Among these, it is also worth mentioning the sample garden around the building, which will showcase the Leier Kaiserstein decorative paving elements (paving stones, paving slabs, fencing), while the Durisol noise barrier and Durisol raised bed will be installed after the final façade design.

Newer products already in use:

• Leier partition: the space-saving design of the Leiertherm 10 N+F brick allows the use of only 10 cm thick non-load-bearing partitions.
• Leier LSK20 chimney: "We connected our chimney to a wood-burning, closed-burner fireplace, which also serves as a backup heater in the model house, adding to the cosy atmosphere of the kitchen-dining-living room area," the consultant added.

Leier Granite Brilliant Roof Tile: New silver grey flat tile with a modern look and brilliant coating that gives excellent protection to the roof; it has excellent wear resistance, long-lasting colour protection and, thanks to its silver grey colour, high heat reflectivity, improving both the durability of the roof and the indoor climate.

A change of mindset is also needed to create such a building, as the technology has the advantage of prefabrication: less live and on-site work, consolidated workflows, resulting in shorter construction times and more efficient construction. However, it is more challenging in the design process, where coordination between disciplines is key: you need to know the details of most solutions at the design stage.

"The exact size and location of all planned equipment, machinery and fittings must be specified and finalised at the design stage, because concrete technology makes it difficult or impossible to modify systems connected to walls and slabs later on," the designer warned.

Furniture is coming slowly

In February, the construction work gathered momentum: plasterboard suspended ceilings and lobby walls, electrical and mechanical installations, fireplace installation, surface preparation, subfloor concreting, cold and hot tiling, painting.

"We expect to start the carpentry work in the second week of March," Zsuzsanna Parádi said, "and the installation of built-in furniture and furniture, ceiling and wall lights, stair and gallery railings can begin. We're getting more excited by the week as we see the final building from plan to reality."

Many actors are working on the case

It is natural that the construction of a building, even a single-family house, is a multi-stakeholder process, and the good functioning of a building is created by the harmony of systems linked to the different disciplines. This is how the building brings together outstanding professional solutions from different disciplines.

Daikin Hungary has installed a Daikin Altherma 3 R 8kW heat pump system here, with heat distribution provided by prefabricated Leier climate walls and climate ceilings, supplemented by underfloor heating in each room. In addition to choosing Baumit Hungary products for machine plastering, the company’s products have also proved useful during the structural construction phase: the Leier shell walls must be filled with concrete on site. In the process, the surface may not be flawless – in such cases, the Baumit concrete repair system offers a solution. With the help of NRG Services Kft., solar panels now also contribute to the building’s sustainable operation. Hofstadter Nyílászárók Kft. has installed premium WoodStyle timber-aluminium façade windows and doors in the show home using RAL installation technology, whereby Illbruck strips ensure that the insulating foam is protected from vapour and moisture both inside and out. The Roto Designo roof windows help bring fresh air into the house with a single movement. The Austrotherm Hungary 8 cm thick thermal insulation layer was covered with heat-reflective foil, then the mesh, followed by the Wavin Magyarország supplied heating pipes.
