NEW BUILD

Building a new structure in Japan is an exciting opportunity to create a space that perfectly aligns with your vision, budget, and lifestyle. Whether you are dreaming of a cozy Off-Grid Tiny House, a private family residence, a luxury ski chalet, or a large-scale boutique hotel in Northern Nagano, Ecoplus brings world-class European building science to your project.

We specialize in high-performance timber construction (HOLZBAU), natural eco-materials, and advanced thermal engineering to deliver healthy, resilient, and ultra-comfortable spaces.

Scalable Solutions: From Tiny Houses to Large Commercial Projects

Our Minimal.Energy.House. philosophy scales effortlessly across any building footprint or commercial purpose:

• Tiny Houses & Off-Grid Cabin Retreats: Maximize every square meter with high-density insulation. Perfect for minimalist private getaways or eco-resorts requiring minimal energy to stay warm in severe mountain winters.

• Custom Family Residences & Vacation Chalets: Enjoy a home designed for healthy, year-round living. Experience zero temperature swings between rooms, continuous 24/7 fresh air, and non-toxic natural materials.

• Hotels, Multi-Unit Chalets & Large Commercial Developments: For large-scale projects, we collaborate directly with external architects, engineering firms, and general contractors. While the main contractor manages the primary construction, Ecoplus takes full charge of the specialized insulation, airtightness, and thermal envelope work. This ensures your commercial venture achieves true European energy standards, drastically reducing operational heating costs and guaranteeing maximum guest comfort.

The Ecoplus Advantage for New Construction

• Swiss Timber Engineering ("HOLZBAU"): Guided by our Swiss-trained master carpenter, we combine European timber framing precision with time-tested local craftsmanship.

• The Specialized "Thermos" Envelope: From foundation to roof, we wrap your new build in continuous, vapor-permeable insulation (such as Pavatex wood fiber). This keeps freezing mountain air out while allowing internal wall cavity dampness to escape naturally.

• Integrated Air & Humidity Control: Built-in whole-house ventilation systems ensure your indoor climate is constantly refreshed—eliminating dry winter air discomfort and muggy summer humidity.

• Sustainable & Carbon-Negative Materials: We prioritize renewable timber and natural wood-fiber insulation that actively store carbon, turning your new build into a sustainable asset.

Flexible Architectural & Building Partnerships

From private self-builds to complex commercial developments, we adapt to your project structure:

• Full Project Execution: Complete design and construction for single-family homes, chalets, and tiny houses.

• Specialized Subcontracting (For Large Projects): We partner with your appointed architects and general contractors strictly to execute the high-performance thermal insulation, vapor control, and airtight sealing.

• DIY Collaboration: For private builds, we handle the critical structural and insulation work while allowing you to complete manageable interior finishings to personalize your home and optimize costs.
