The “Income House” Project
In October, we welcomed a new partnership with Income House — a striking example of how three small construction companies in Georgia, discovered through Facebook, united under a shared vision and secured a 6-hectare plot of land for the first stage of the project bearing the same name.
This collaboration demonstrates how talented people can form cooperatives and become partners based on shared values and goals. By combining their collective expertise and a common mission, the Income House project highlights the strength of partnership in creating sustainable, community-focused developments.
The “Income House” Project:
Hello,
We assure you that a modern modular home built to the Passive House Standard looks no different from a conventional building — yet it far surpasses it in comfort, efficiency, and sustainability.
When you purchase a 250 m² home from GDB Passive House, you unlock several additional income opportunities. Each home comes with a 35 kW solar power system installed free of charge, allowing you to sell surplus energydirectly to charging stations and smart energy networks. This innovative feature can generate up to USD 3,000 in extra annual income, while also reducing your household’s energy costs and carbon footprint.

We produce one model of a private home at GDB Passive House — but this home comes with a range of unique advantages!
A 250 m² home from GDB Passive House can be purchased through commercial leasing, with only 30% of the total cost required as an initial payment — available for any configuration level.
At the Premium / Passive House Level (USD 1,500 per m²), you receive a fully furnished, move-in-ready homedelivered within just 4 months from the date of advance payment!
Concept: “LEGO Layout” of the GDB Passive House 250 m²
The project features a functional layout of a modular single-story home totaling 250 m², composed of 8 modules, each measuring 2.4 m × 13 m (≈ 31.2 m² each).Total area: 8 × 31.2 = 249.6 m² — a perfect match.
Such a fast timeline is possible thanks to industrialized modular technology and standardized Passive House design, ensuring energy efficiency, sustainability, and long-term comfort.
Each module is an elongated block (2.4 × 13 m), connected by doors or arches. Below is the sequence and description of each module, with approximate dimensions and connections:
GDB Passive House 250 m² — Efficient Modular Living
The GDB Passive House 250 m² is a modern, single-story modular home built from eight high-performance modules. Each unit is factory-produced under strict quality control and assembled on-site with precision — just like a full-scale “LEGO house.”
From the moment your advance payment is made, the entire process — manufacturing, delivery, and on-site installation — typically takes only 2–3 months.
This includes complete production of all modules, factory finishing, logistics, and the final assembly on your land.

Innovations in Modular Home Construction
Innovative technology for building modular houses The construction utilizes multiple layers and concrete slabs, resulting in high strength and good insulation of heat and noise. On the outside, a diffusion membrane is placed on the frame, which allows vapor diffusion but prevents the passage of moisture. The wall is then sheathed with 12mm thick cement-bonded particleboard (CBC). The particleboard is an environmentally friendly material.
Technology for the construction of a low-slope roof for installing a 35 kW solar power station
A schematic sectional drawing illustrates the eight-module composition with a gradual height increase from 3.000 m (Module 1) to 3.800 m (Module 8), using interconnected modules of 2.4 × 13 m each.
The current design represents a smooth, gentle rise: a total elevation difference of 0.8 m over 104 m of building length, resulting in a very shallow slope (≈0.77%). This configuration is convenient for construction and module alignment but does not create a visually noticeable roof incline.

This approach allows homeowners and developers to receive fully functional, eco-efficient housing units anywhere in the world with minimal construction time and predictable costs.
Global Trends in Modular Home Manufacturing: 2025–2030
The modular housing industry is entering a new era of innovation and sustainability. Around the world, modular construction is becoming a key solution to the growing demand for affordable, energy-efficient housing. Between 2025 and 2030, the sector is expected to focus on eco-friendly materials, digital production technologies, and energy-neutral building concepts.
A major driver of this transformation is the Passive House Standard — a rigorous energy-efficiency benchmark originating from Europe. Passive House buildings consume up to 90% less heating and cooling energy compared to traditional homes. They achieve this through advanced insulation, airtight construction, heat recovery ventilation, and optimized solar gain. By integrating these principles into modular production, manufacturers can deliver high-quality, factory-built homes that meet global climate goals and provide long-term comfort and affordability.
A house made of concrete, panels, or modules? When it’s built to the Passive House standard, it doesn’t matter — the interior and atmosphere always impress with their warmth and comfort!
Attention! Please also review and apply the "Assumptions" used to adjust the Construction Protocol for the temperatures in Georgia!
Here are some countries and regions where the Passive House standard is already being applied, including in modular or off-site construction contexts:
-
United Kingdom — For example, a volumetric modular housing development in Cardiff was built to the “Passive House Plus” standard using off-site modular units. unlocknetzero.co.uk+2Offsite Hub+2
-
Spain — Prefabricated modular houses built to the Passive House standard are available on the Spanish market. idealista.com
-
Sweden / Scandinavia — A Swedish-based factory is producing timber-frame modular wall sections designed to the Passive House standard for export. scanhome.eu
-
Germany & broader central Europe — Germany is a foundational region for the Passive House standard and has many certified buildings and localities that adopt the standard in legislation. passivehouse-international.org+1
