We design and build prestige homes with a timber frame and in-situ cast hemp-lime walls — bespoke, for those who choose to live in harmony with the natural world.
Pioneers of natural prestige architecture in Italy.
2019Year of founding
Conventional construction accounts for roughly 40% of global CO₂ emissions. H.0.ME. was founded to prove that building better is entirely possible — and that “better” means healthier, more beautiful and more enduring.
We are a bespoke construction and consultancy atelier for prestige properties, based in Avellino. We design and build with a timber frame and hemp-lime walls, using the certified Hemp Eco Systems (Switzerland) construction system — 25 years of research and development, now available in Italy.
We do not build in series. Every project begins with deep listening: to the client, the site, the light. We bring together engineering, architectural and research expertise to provide comprehensive consultancy — from the first conversation to final sign-off.
Building system certified by Hemp Eco Systems (Switzerland) — international patent US 10,266,451 B2. We employ the HES system across our projects.
We use the only hemp-lime biocomposite carrying the European CE certification LVS EN ISO 17050-1. Performance data measured at Vilnius Gediminas University and the BRE Centre, University of Bath — not self-declared.

Bespoke, never mass-produced
We do not build in series. Every project begins with deep listening — to the client, the site, the light. Our deliberate scale is a quality choice, not a constraint.
03
Certified carbon-negative
Lime recovers up to 60% of the CO₂ emitted during calcination. Hemp shiv continues to sequester it throughout the entire life of the building. Life Cycle Assessment data in support — not marketing claims.
04
Scientific, multidisciplinary approach
Engineers, architects, researchers — full coverage from concept to sign-off. Collaboration with Tecnovia S.r.l. (MIUR-qualified laboratory) and advanced training at Palazzo Fortuny, Venice.
05
International US patent
The system is grounded in patent US 10,266,451 A1 (PCT/CH2015/000085) — a method for producing the hemp-lime biocomposite with a patented volcanic additive (HES-Plus). 25+ years of European R&D.

Evidence, not opinions
Proof in the field.
Measured results of the building system we use — in the lab, in a classroom and on a protected historic landmark.
−71,7 t CO₂ per building
Carbon-negative balance, calculated
CO₂ avoided versus an equivalent brick-and-concrete home, on a 150 m² reference house. Not a marketing estimate: a Life Cycle Assessment, transport included.
H.0.ME. LCA study
−27% indoor CO₂
Healthier air, proven in a classroom
Two identical classrooms, monitored under real occupancy: the only difference was 1.5 cm of HES-Wall render. Peak CO₂ cut by 27%.

Durability over time, on a protected landmark
HES render applied to a protected historic building and checked by thermography after two years: no detachment, no decay.
Every project is carefully chosen. We work exclusively with natural materials. Every service begins with a bespoke consultation.
01
Prestige Homes in Timber & Hemp-Lime
We build bespoke high-end residential and non-residential properties from the ground up — timber structural frame, hemp-lime envelope cast in situ with the certified Hemp Eco Systems system. Every building is unique: designed for the client, the site and the climate. Zero cement, zero compromise.
We accompany you from concept to executive design. Technical feasibility studies, architectural design, structural and seismic assessment, energy certification, specification with natural materials. Also available for third-party projects seeking to incorporate the HES system.
We operate as developer for residential and commercial real estate projects using natural construction technology — from land scouting to the finished property, destined for sale or premium rental. The HES system as a market differentiator and source of added value.
Restoration and refurbishment of historic buildings, villas and prestige properties exclusively with natural materials and techniques compatible with the existing fabric — HES-Wall™ renders, rising damp remediation, acoustic and thermal improvement without altering the character of the place.
The essentials on hemp-lime building, costs, guarantees for international clients and where we build.
What is hemp-lime (Hemp Eco Systems) construction?
It pairs a timber load-bearing frame with walls of a hemp-hurd, lime and natural mineral biocomposite (HES-mix), cast in situ as a monolithic wall — with no joints and no thermal bridges. The result is a natural, breathable, highly insulating, CE-certified wall.
Is a hemp-lime home fire-resistant and suitable for earthquake zones?
Yes. The biocomposite has a CE-certified B-s1-d0 fire reaction class, and the timber load-bearing frame is inherently light and ductile, making it well suited to Italy’s seismic zones.
How energy-efficient is it? Is it really carbon-negative?
At 35 cm of HES-mix in climate zone D it reaches energy class A4. The material absorbs CO₂ across the building’s whole life cycle (hemp sequesters carbon as it grows), making it carbon-negative — with zero cement.
Do you work with foreign clients and investors? How are payments protected?
Yes — we act as a General Contractor for international investors building or renovating prestige properties in Italy. Payments are protected through a notary deposit and escrow tied to construction milestones (SAL), released by an independent surveyor, with a single point of contact for the whole project.
Where does H.0.ME. build in Italy?
We are based in Campania (Avellino) and operate throughout Italy, with a focus on areas with strong international appeal: the Amalfi Coast, Cilento, Salento, Tuscany/Tuscia, Marche and Monferrato.
Can you renovate a ruin or an existing villa with natural materials?
Yes. Beyond new builds, we renovate fine properties and ruins with natural materials: the HES-Wall render is applied over masonry, concrete, stone and plasterboard and is ideal for remediating rising damp.
