Frequently asked questions

What is an Eco-home?

This is a house that is designed and built with consideration for ecological principles, climatic conditions, and minimal resource usage. During construction, exclusively natural materials and energy-efficient technologies are used, which reduce energy consumption and costs for heating and air conditioning.

How fire-safe are straw homes?

Compressed straw lacks the necessary amount of oxygen to sustain combustion and spread flames. The panels are treated with a clay plaster layer that transforms into clay-ceramic under high-temperature pressure. Test results show that a straw panel withstands temperatures of 1000°C for one hour, meeting building codes for cottages up to 3 stories. For multi-story buildings, a load-bearing structure made of concrete or metal is mandatory.

Do rodents threaten the house?

Rye straw contains no nutrients for rodents and is not an attractive material for pests in its compressed state. The wooden frame is treated with a fire-bioprotective compound that has powerful universal action, ensuring the wood's biostability against common microorganisms and fungi. Based on the living experience of straw house owners, no pests inhabit the walls. However, additional rodent-proofing measures exist for peace of mind.

Why is breathing easier in an Eco-home?

Straw has a capsule structure and retains its filtration properties when compressed. The walls of a straw house act like a giant natural micro-filter, enabling continuous air exchange. This characteristic is why straw homes are called 'breathing' structures.

What about mold and fungi?

Interiors of straw homes are finished with a clay plaster layer that self-regulates air humidity, redirecting excess moisture through the capillary structure of straw to the outer wall layer. The absence of excess moisture condensation reliably protects walls from mold and fungi. Clay is a hypoallergenic material that can adopt any color or texture and feels pleasant to the touch.

What is the lifespan of straw homes?

The reliability of the construction system is ensured by meticulous selection of natural materials, thorough development of manufacturing technology, and quality control during production. Homes built with straw panels are designed for 5 generations. Similar houses have stood for over 100 years. An example is a straw house built in 1921 in France that remains inhabited today.

Why are straw homes called energy-efficient?

400 mm thick straw panels provide thermal insulation equivalent to 5 meters of brick walls. The construction technology allows building a «Passive House» where annual energy consumption for maintaining comfortable temperatures does not exceed 15 kWh/m². One such home was built in 2019 in Kyiv Oblast.

How does the exterior of straw homes differ from 'traditional' ones?

Straw panels impose no design limitations. Exterior plaster can achieve both perfect wall textures with sharp angles and soft forms typical of eco-homes (built with adobe). A ventilated façade allows exterior finishing with any material, including imitation brickwork or clinker tiles if required.

What is the cost per m² of a straw panel home?

The home's cost depends on geodesy and geology of the plot, developed house design, chosen finishing materials, approved engineering systems, ceiling height, and window sizes. The average cost for a 100m² finished home starts at 650€ per m² of floor area per level. For eco-village projects, the cost per m² decreases significantly due to optimized organizational and transportation costs for material delivery.

What heating system is best for a straw home?

Straw homes have no restrictions on heating systems. Engineering design must consider available energy networks and their costs. Water-based underfloor heating has proven effective as one of the best systems for maintaining comfortable temperatures. For properties without energy networks, solid fuel heating or wind/solar stations are optimal solutions.
