Build faster, beautiful and efficiently

Building System

CITRA makes use of cost-effective and recyclable construction materials with excellent insulation properties and a low impact on the environment.

CITRA alternative building system has been accredited and approved by various engineering and building councils, organisations and institutions.

Look inside our technology


A beautiful design, green approach and robust structure

Design Versatility

CITRA innovative building system can take any shape at no extra cost, by making use of precision computerised machines.

Faster Construction

Time is money in construction and CITRA modular houses can be built much faster and less invasive than standard on-site conventional building systems.

Energy Efficient

CITRA system has high thermal resistance, with a R-value 2.2 m²K/W. Cool in summer and warm in winter

Affordable Quality

CITRA system is not only strong and of a high performance compared to other alternative and conventional building systems, it is more affordable. Try it for yourself with our Free Quotation Tool.

Robust Home

The seamless CITRA design makes the panel’s ensemble easily and this together with the comparative lighter-weight structure, reduces the potential for structural defects, withstanding earthquakes and winds of up to 250 km/h.


CITRA system is able to reduce pollution and costs, both, during construction and life cycle,
Reduced work on-site and transport have a huge impact on the reduction of CO2 emissions.
90% or our materials are completely recyclable.

Strong Structure

The strength of the CITRA walls can hold up to 136 kg without any damage (40 kg more than a large TV).

Water Proof & Fire Resistant

CITRA building system is water impermeable, durable, and a fire rating of 1 hour (double than brick and mortar).


Photovoltaic panels can be installed on the CITRA plaster without additional structural elements.

cutting edge building technology
The exterior is coated with a synthetic material that is weather resistant. It shows none of the usual weaknesses exhibited by standard external paint, such as cracking or spalling.
The EPS & MgO boards are assembled between glass fibre mesh and reinforced plaster.
The external plaster is up to 6 mm thick. A copolymer additive makes it robust, waterproof and elastic. The internal plaster is 30 mm thick, helps to regulate humidity, and can be used for the same decorative purposes as traditional walls.
The core material is a 180 – 240 mm thick EPS 15, which has excellent thermal insulation properties and makes an extremely durable structure.
MgO is an environmentally friendly, non-toxic material, that provides strength and insulation, joining the panels together.
Solar panels can be attached without the need of an additional structure.

The CITRA Building Structure

Our building system makes use of well-established building materials such as expanded polystyrene (EPS), magnesium oxide (MgO) board and fibreglass mesh.
