UnderPearl is a smart (zero energy) building for a secure future.

It is bi-functional in design:

• for everyday living, without sacrificing the comfort of above-ground living
• and at the same time a high-tech automated shelter that offers safety in all extreme situations.

It combines a cutting-edge design that can be customised, state-of-the-art safety equipment and complete (space-age) autonomy when you need it most. UnderPearl provides a new dimension of safe living in a world of uncertain futures and climate change.

UnderPearl – is a brand under which we developed Smart Buildings for a Safe Future.

Hybrid Building – holistic description of Smart home + fully automated Shelter – UnderPearl.

Hybrid Structure – term used to describe the technical aspects and other properties of UnderPearl Smart Buildings.

Hybrid Shelter – term used to describe manly the safety features of the UnderPearl Smart Buildings.

Yes, every UnderPearl Smart building is fully customisable. Construction of the basic modules is already underway, so future owners can join mid-project and customise it to their preferences, ensuring faster delivery.

Customers can choose from a variety of luxury materials, room layouts and additional features such as a spa, a men’s den – bar, music studio, games room, etc.

They are available in different sizes, from 12 m² (net living area) to over 100 m², with the possibility of a modular assembly.

The main advantages of the UnderPearl Hybrid Shelter are:

• The highest level of protection and security in all extreme situations (hurricanes, fires, viruses, floods, nuclear explosions, earthquakes, wars, etc.).
• Autonomy with its own energy, air supply, ventilation and water systems.
• Luxurious interiors with customisation options.
• Intelligent technologies for control and comfort even in the most severe situations.
• Zero energy building (constant temperature)
• Comfortable sleeping areas with the possibility to enrich the air with oxygen while you sleep
• Smart control system that automatically switches to protected mode which danger we are facing (virus, fire, radiation, …).

UnderPearl structures are constructed with special, highly resistant and modern materials such as ballistic resistant steel, advanced composites and insulation materials to ensure safety and durability, reinforced concrete, as evidenced by numerous awards and certifications at regional and international level.

UnderPearl shelters can operate fully autonomously for weeks or even months (depending on oxygen reserves), thanks to advanced ventilation systems, energy storage (solar panels, batteries) and water storage.

The range of situations in which UnderPearl offers protection is considerable, and includes protection:

• against natural disasters (fires, earthquakes, floods, storms),
• social unrest (robbery, vandalism, burglary, attack with light or heavy weapons),
• war threats (viruses and other biological weapons, drone attacks, nuclear radiation and explosions, etc.)
• and long-term crises such as energy and nutritional disruptions (with an adequate stock of suitable food).

The shelters include unique ballistic-resistant, gas-tight, water-tight, radiation-resistant doors, filters to protect against biological and chemical threats, an ambient pollution control system, smart security systems and energy systems to make living comfortable.

UnderPearl hybrid buildings can be installed almost anywhere, including underground spaces under homes, backyards or even in remote locations where weather conditions are severe. Installation can be as a fully buried structure, a partially buried backfilled structure or an above-ground covered structure.

Base module construction is already underway, enabling future owners to join mid-project and customize it to their preferences, ensuring faster delivery.

Construction time also depends on size and customization level, but typically takes between 4 and 12 months (all phases of production: design, customization, fabrication and installation included).

The price varies depending on the size, customisations and additional features. Basic models start in the €60,000 + VAT price range and offer a wide range of safety features. High, customisation, safety and autonomy, like spacecraft, start in the €350,000 + VAT price range. To discuss your requirements individually, please contact us and we will provide you with a personalised cost estimate.

Yes, UnderPearl’s hybrid shelters are certified tested and not only meet the highest international standards for safety, but are also tested to withstand extreme conditions, including ballistic blasts and natural disasters. In many cases, Underpearl’s hybrid buildings significantly exceed the technologically outdated minimum safety standards for public shelters.

Yes, for optimal performance, we recommend maintenance including inspection of ventilation, energy and security systems. The UnderPearl hybrid shelter has built-in sensors that provide timely warnings of any deteriorated or worn-out built-in filters and elements, and our team provides comprehensive support and maintenance for your UnderPearl hybrid shelter.

An UnderPearl hybrid building is considered a basement in most European regulations. However, the need for a building permit for the installation of a basement depends on the criteria set out in each country’s legislation and local regulations.

Most commonly, a basement is referred to as:

1. Simple constructions
having a surface area of up to 20 m², irrespective of the depth of the excavation and the underground parts. Also check that your project meets all local regulations and installation requirements.

2. Non-complex constructions
has a surface area of up to 50 m² and a maximum of two storeys, irrespective of the depth of the excavation. You submit an application for a building permit to the administrative unit.

Recommendation
Before starting construction, we advise you to:

• Contact the municipal administration: to check the local regulations and to obtain location information on the permitted construction activities on your land.
• Consult a construction expert: Authorised designers can help you to review the location information and prepare the relevant documentation.
• Get further information: Contact the building department of the administrative unit to check the requirements for your case.

This process will ensure compliance with all regulations and smooth construction progress.
