ARCHITECTURAL FIT-OUT

INSTALLATION ENGINEERING.

75x75 cm Modular Panel.

Technical format for large surfaces, flexible for cladding columns. It adapts on-site with the same efficiency and cleanliness as a plasterboard sheet.

  • Ultra-fast installation (Zero Waste): Guaranteed base yield of at least 25 sqm/day per operator, with tested peaks of 2.18 sqm in 7 minutes on linear walls. Offcuts fit together perfectly (seamless), eliminating waste.
  • Ready-to-Deliver European Logistics: Panels in individual protective boxes. A base pallet (80x80 cm) holds 20 panels for a featherweight of only 70 kg.
  • Dedicated Batch: Large quantities of raw material are selected and mixed in a single batch to guarantee absolute homogeneity.
    The entire supply is strictly processed by the same artisan hand, eliminating the risk of color variations on the wall.

Industrial Tailoring (CNC Cutting).

We mill complex architectural layouts using Numerical Control (CNC). Goodbye to paper templates and imprecise manual cuts.

  • The panel is the template: It arrives at the construction site already shaped to your measurements, numbered, and ready for fixing (1:1 scheme).
  • Infallible precision: Installs in minutes, bypassing switches, monitors, and fixtures without any margin for error.
HUMAN PERFORMANCE INDEX 2026

IT DOES NOT DECORATE.
IT REGENERATES.

  • Cognitive Focus: Inert surfaces (plaster, glass) increase mental load and reverberation. Preserved Moss "cleans" the environment, promoting clarity and prolonged concentration.
  • Biophilic Impact: Curtains and fabrics are decorative but biologically "mute". Green Habitat triggers the innate biophilic response, visually reconnecting humans to the natural environment.
  • Zero Cortisol: Gray and sterile spaces raise stress levels (Sick Building Syndrome). Our ecosystems reduce heart rate and create an immediate decompression oasis.
CONCRETE AND MASONRY

Inert environment. No natural stimulus, high reverberation, no reduction in perceived stress.

PRODUCTION AND LOGISTICS:

LARGE-SCALE PRODUCTION CAPACITY.

  • "Single Batch" Processing (Zero Checkerboard)
  • Material Stock Ready for Delivery
  • Technical Packaging and European Shipping
The secret to perfect homogeneity: Our enormous industrial capacity allows us to mix the entire supply of lichen in a single "Single Batch". The installation is then performed by a single artisan hand, ensuring absolute visual fluidity even on monumental square footages and avoiding the classic "checkerboard effect".
CUSTOMIZATION:

CUSTOM DESIGN AND CNC CUTTING.

  • Independent Logo (Unscrewable, Reusable Wall)
  • Millimetric shaping to design
  • Customizable textures
Protecting your Investment: We faithfully reproduce your brand by placing it independently overlapping the plant wall. In case of a trade fair, you can unscrew it and take it with you. In the event of a corporate relocation, the underlying lichen panels will be perfect and reusable elsewhere.
INSTALLATION:

DRY MECHANICAL SYSTEM (DRY TECH).

  • Clean and night-time site (Zero Corporate Downtime)
  • Quick nail/screw fixing (Without Glues)
  • Free engineering supervision
Trauma-free installation for business: The Dry Tech system is completely dry (screws on plasterboard or nails on walls). Zero glue, zero drying times, zero dust on the floor. This allows installations to be carried out even at night: the staff will find a regenerated office the next morning.
MAINTENANCE:

ZERO OPERATING COSTS (OPEX).

  • No Water, No Light, No Pruning
  • 100% Natural and Biodegradable
  • Anti-static: does not attract dust
No management expenses: Unlike walls with living plants (which require water pumps, sunlight, and gardening contracts), our preserved moss naturally absorbs air humidity while remaining vital. The anti-static treatment repels dust, totally eliminating post-sales maintenance costs.
PRODUCTIVITY:

IMMEDIATE "DAY 1" EFFECT.

  • Guaranteed Yield: at least 25 SQM/day (Peaks: 2sqm in 7 min)
  • Total agility (Use on a cherry picker)
  • Plug & Play Architectural Approach
Unmatched speed: We guarantee a basic site yield of at least 25 square meters per day per individual operator, but we have documented peak performances of over 2 sqm installed in just 7 minutes. As demonstrated by the monumental 3-story wall in the Pieri Group video, two operators on a cherry picker can complete a massive installation in a single working day.

2.18 Sqm installed in exactly 7 minutes.

No theories, just construction site efficiency. Watch the full video (uncut) of a single operator installing and trimming over 2 square meters completely autonomously in just 7 minutes.

B2B KNOWLEDGE BASE

The Moss Encyclopedia.

From natural preservation biotechnology to international architectural protocols, up to the most common doubts. We have analyzed the questions of designers, General Contractors, and end customers to offer you unequivocal and transparent answers.

Origin, Nature and Safety

1. How does the preservation process work? Are toxic substances used?

Our Nordic moss (Cladonia Stellaris) is 100% natural. The ecological preservation process replaces the lifeblood with a non-toxic mixture based on natural salts, vegetable glycerin, and food-grade pigments. This treatment stops the aging of the plant, making it an inert, biodegradable, and zero VOC (Volatile Organic Compounds) emitting material, guaranteeing healthy air.

2. Does preserved moss emit bad odors or chemicals?

Absolutely not. Green Habitat uses very high-quality purified glycerin. Immediately after installation, you will perceive a slight and pleasant scent of natural undergrowth, which will fade physiologically within a couple of weeks, leaving the wall totally odorless and neutral.

3. Is it safe or poisonous for children and pets (dogs and cats)?

It is totally Pet-Friendly and safe. Unlike many live houseplants (like Poinsettia or Ivy) which are toxic if ingested, our moss, thanks to the exclusive use of salts, vegetable glycerin, and food coloring, is neither poisonous nor harmful in case of accidental contact or ingestion.

4. Does harvesting the moss damage the Nordic forests?

No environmental damage. The raw material is rigorously hand-picked in controlled forest areas of Northern Europe. The harvest is authorized and takes place only in specific time windows and limited percentages, allowing the perfect regrowth and renewal of the tundra ecosystem.

5. Is it a fire-certified material for public venues or offices?

Yes. The natural salts used in the process act as formidable ecological flame retardants. Our panel possesses the official fire reaction classification Class B-s2, d0 (European Standard UNI EN 13501-1) issued by the Istituto Giordano (Report No. 369047). It is hardly flammable and guarantees the total absence of burning droplets.

Environments, Installation and Limits

6. Does it need sunlight? Can I install it in windowless bathrooms or dark corridors?

Yes, it lives at 0 Lux (total darkness). Since the lifeblood has been replaced, the moss no longer performs chlorophyll photosynthesis. It does not require any source of sunlight or phytostimulating lamps (UV). It is the ultimate architectural solution to bring biophilic design into windowless bathrooms, corridors, underground meeting rooms, or elevators.

7. Can I use it outdoors or in a shower cabin?

NO, it is designed exclusively for interiors (Indoor). Exposure to the elements (rain, frost) or direct contact with liquid water (e.g., a shower jet) would wash away the salts and glycerin, destroying the panel. If installed indoors and away from direct water, it will last for years.

8. Does the color fade over time? Does it resist solar UV rays?

To guarantee maximum chromatic brilliance for its entire lifecycle (8-10 years), it is essential not to expose the wall to direct and prolonged sunlight (UV rays shining through windows) and to keep it away from intense heat sources (radiators in contact). Normal diffused sunlight and LED lighting do not create any problems.

9. Will my plasterboard wall hold the weight of the green wall?

Yes, without any structural reinforcement. Our 75x75 cm modular panel has a featherweight that ranges between 5.3 and 5.9 kg per square meter. It is mechanically dry-fixed (Dry Tech) directly onto normal plasterboard sheets using simple screws.

10. Is it flexible? Can I use it to clad circular columns?

Absolutely yes. The MDF backing of the Green Habitat panels is only 3mm thick and is extremely flexible. It is engineered to follow the geometries of the building, allowing you to perfectly clad circular pillars and columns continuously and without visible joints (seamless).

Maintenance, Health and ROI

11. Humidity at 40-60%: Is it a limit or a guarantee of human health?

It is a guarantee of health. Global guidelines on Indoor Air Quality (ASHRAE, EPA, and WHO) document that maintaining indoor humidity between 40% and 60% is the only condition that inhibits viruses, bacteria, mites, and prevents respiratory dryness.

Our moss acts as a Passive Bio-Hygrometer: it stays soft exactly in this range. If it is soft, you have visual proof that the office air is healthy. If it hardens, it warns you that the air (often due to air conditioning) has become too dry and unhealthy.

12. What happens if it dries out (below 40% humidity)? Does it die?

It does not die and does not get ruined. Preserved moss is hygroscopic (it works like a sponge). If the humidity drops below 40%, it simply hardens to the touch. It should not be touched and must never be sprayed with liquid water. It is enough to restore the correct humidity in the room (with a humidifier or by ventilating) and the moss will autonomously return to being soft and vital in a few hours, absorbing moisture from the air.

13. Does the moss attract dust or insects over time? How is it cleaned?

The glycerin-based treatment gives the material strong antistatic properties, naturally repelling dust accumulation. Being inert and soil-free, it provides no vital habitat: it does not attract insects or parasites in any way. If dust settles during the construction phase, an electrostatic duster or the jet of a hair dryer with cold air from a safe distance is sufficient.

14. Do moss walls contribute to LEED and WELL credits?

Yes. Although no single material can be "LEED Certified", the inclusion of our biophilic walls actively supports designers in obtaining green building credits.
  • WELL Building Standard v2: They meet the requirements of the Mind / Biophilia (Access to Nature) and Sound (Acoustic Comfort) chapters.
  • LEED v4.1: They contribute to the Indoor Environmental Quality (thanks to Zero VOC Emissions) and Water Efficiency (thanks to Zero Water Consumption for maintenance) credits.

15. How is the quote calculated and what is the ROI of the investment?

The true evaluation parameter in B2B is the Total Cost of Ownership (TCO) over 5 years. Living vertical gardens entail huge continuous hidden costs (plumbing, phytostimulating lighting, water consumption, and gardener subscriptions). Preserved moss has an operating and maintenance cost (OPEX) of zero. The initial investment, based on Square Meters and Custom processing, pays for itself in a very short time.
