APUS I

A – BRICK (CLASSIC MASONRY)

Solid brick construction with high thermal mass, excellent acoustic performance, and long-term durability. This traditional system features load-bearing masonry walls, a selectable ceiling structure, and a timber roof. A timeless and proven method suitable for a wide range of environments.

B – TIMBER FRAME

Lightweight wood-frame system designed for precision, fast construction, and sustainability. Offers high insulation performance, reduced material consumption, and excellent suitability for modern energy-efficient homes.

C – CLT (CROSS-LAMINATED TIMBER)

Mass-timber system using CLT panels for walls, floors, and roof. Provides outstanding structural stability, architectural flexibility, and a warm natural interior finish. Ideal for contemporary and eco-conscious construction.

D – TIMBER FRAME (ALTERNATIVE FOUNDATIONS)

Lightweight timber-frame system designed for precision, fast installation, and sustainability. Built on simplified foundations — concrete footing pads or screw piles — allowing minimal excavation, lower environmental impact, and excellent adaptability to uneven or sensitive terrain.

E – CLT (ALTERNATIVE FOUNDATIONS)

CLT-based mass-timber system adapted for simplified foundation types such as concrete footing pads or screw piles. Combines the robustness and architectural quality of CLT with rapid installation, minimal site disturbance, and suitability for challenging or irregular terrain.

H – TECHNOLOGY PACKAGE

A set of mechanical, electrical, plumbing, HVAC, and solar components forming the project’s integrated technical infrastructure. The exact scope of included systems varies by project — always check the specific project description to verify which components are part of this variant. The specific climate parameters and temperature range for which the system is designed are also defined individually in each project description.

Z – CUSTOM DESIGN

Automated custom design generated from user-defined parameters via an online configurator. The user defines key inputs such as building dimensions, room layout, window and door sizes and positions, roof type, and roof pitch.

After clicking DESIGN CUSTOM PLAN, the input data is processed by an automated backend workflow that modifies the master model in Revit. The system then delivers a fully customized project including BOQ, interactive 3D GLB models, and PDF/DWG documentation.

This variant can be extended with the x execution budget, creating Zx — a custom-designed project enhanced with detailed execution data based on real-world construction experience.

x – EXECUTION BUDGET (EXTENDED VARIANT)

A lowercase x added to any variant (e.g., Bx, Dx, Ex) indicates an extended execution budget — an expanded package created by the author who has built the project in real life from start to finish.

Each item includes:

• Mandatory fields: Time Duration, Workers, Difficulty, Notes
• Optional fields: Timeline, Video Tutorial, Additional Costs

The price of the x variant is increased by 1 USD for every item in the budget that contains at least the mandatory fields.
Example: If the budget contains 85 items and 60 items have all mandatory parameters filled in, the x variant is priced 60 USD higher.

FACADES

Each structural variant offers two façade options:

• ETICS (contact insulation system)
• Ventilated façade system

M – FURNITURE & INTERIOR PACKAGE

Optional upgrade including interior furniture, built-ins, and equipment to complete the full spatial layout and interior design.

3D INTERACTIVE MODELS (GLB)

All variants include interactive 3D GLB models. Explore structure, layers, technologies, and interiors from any angle — providing a clear and intuitive understanding before construction begins.
