Low Cost Housing – low-cost housing made of concrete

The solution for crisis regions and poor population groups

The “Low Cost House” concept is the solution for fast-growing and poor population groups that need high-quality housing. Governments and aid organisations that are dependent on rapid first aid in crisis areas with large numbers of refugees or after natural disasters can also create safe accommodation with the Low Cost House.

The building concept of a massive concrete house developed by B.T. innovation provides a quick solution for housing people in need. The creation of safe, stable and cost-effective living and utility space can be achieved in just 2 hours with the Low Cost House.

Build a turnkey concrete house in just 2 hours, including 2 rooms, kitchen and toilet and the whole thing on 36 m²? The simple building concept from B.T. innovation makes this possible! Follow the first set-up within 2 hours in our video!

The basic building material for the house is concrete. Concrete is one of the most widely used building materials in the world and can therefore be produced almost everywhere in reasonable qualities with locally available raw materials. It is easy to work with and can be shaped into almost any form. Concrete has good structural-physical properties, is very resistant and is therefore ideally suited for solid, durable structures.

As standard, the “low cost house” concept will be offered with a floor area of 36m² each (see picture). Another feasible size includes a floor plan of 48m².

Depending on the region and demand, two different roof types are also planned. On the one hand, there is the flat roof variant (standard) and a variant with the classic gable roof.

Different variants are possible with the help of the flat roof variant. On the one hand, a multi-storey arrangement of the house with external staircase as well as a semi-detached house variant.

The prefabricated concrete parts of the Low Cost House are produced with the help of a particularly space-saving and transportable battery formwork. This technology enables the production of components in the immediate vicinity of the construction site in the form of a mobile field factory. This form of production has the following advantages over conventional technologies:

  • Simple and easy to handle manufacturing process
  • Formwork-smooth surfaces on both sides, eliminating the need to re-treat the elements
  • Large volume output with relatively small footprint (one house per mould)
  • Flexibility with regard to the suitable production location

Prerequisites for the implementation for the respective use of the house are our technical know-how, as well as the technical equipment. Under the expert guidance of B.T. innovation GmbH, local workers are to learn how to use the equipment. Here they are trained in the production of the elements and the assembly of the prefabricated houses. In this way, jobs are created in the target regions, regional value chains are strengthened and project acceptance is improved.

The elements are transported, for example, with the help of an inloader pallet modified by B.T. Transport of all house elements is possible on this pallet. The advantage of this technology is that the elements are loaded directly onto the load carrier changing system. This avoids cost-intensive reloading work and expensive downtimes for the truck.

In order to be able to realise the short construction time of only 2 hours, so-called “dry” connection techniques are used. The BT-Spannschloss® developed by B.T. innovation GmbH is suitable for this purpose. It enables easy and precise connection of the individual precast concrete elements. No other tools are necessary for the connection. A lot of time and costs are saved this way. After assembly, the BT-Spannschloss® is immediately fully and permanently loadable. For the BT-Spannschloss®, which is already established on the market, the general building authority approval was granted by the Deutsches Institut für Bautechnik.

To protect the house from water, dust and insects, the RubberElast® sealing tape used for “dry” connection techniques is suitable. It can be processed extremely quickly and almost regardless of temperature. The material is securely bonded to the concrete elements by the contact pressure. The material remains permanently elastic. The test certificate from the Braunschweig Materials Testing Institute stands for safety.

InnoElast® is suitable for the individual sealing of concrete, structural joints, joints as well as connections on windows, doors, penetrations and in the roof area.

The precast elements are to be designed in such a way that an extremely high degree of prefabrication can be achieved. Preferably, the individual elements are prepared to such an extent that a house is ready for occupancy immediately after the individual parts are assembled and no or only a few extension and finishing works are required, e.g.:

  • If necessary, wall, ceiling and roof surfaces should be provided with complete surface treatment on the outside and inside. The use of colour pigments, additives or special formulations means that finishing work such as plastering, painting, tiling or wallpapering can be dispensed with.
  • The basic installation for electricity, water and sewage can be completely prepared so that the buildings only need to be connected to the corresponding networks (if available) during assembly.
  • The usual supply routes for the target region, e.g. water and sewage tanks, are to be taken into account in the building design.

In particular, alternative supply options can also be considered, e.g.:

  • Rainwater can be collected via the roof drainage system, channelled into appropriate cisterns and used as drinking or service water.
  • Solar energy can be used to supply the house with energy. The energy generated can be used for electricity, heating and cooling purposes.
