Advanced Acoustic Design
High-density insulation fills every cavity. Blocking impact and airborne noise for absolute privacy between floors.

03 Exterior Wall & Ground System

Your First Line of Defense.

The critical interface between ground and structure. Multi-layer protection engineered to withstand Hawaii's tropical climate.

Multi-Layer Weather Shield
Precision-sealed joints create an impenetrable barrier. Keeping rain and wind out, and comfort in.

Unified Structural Rigidity
Seamless connections distribute loads evenly. Enhancing overall stability and seismic resistance.

Modular Precision
Factory-built. Rapidly assembled. Delivering consistent, uncompromised quality at record speed.

04 Interior Wall System

Flexibility Meets Function.

Non-load-bearing by design. Maximum freedom to adapt your space to your life.

Flawless Finish Integration
Seamless connections between floors and walls. Ensuring perfect stability and a smooth, level surface every time.

Limitless Layout Options
Walls that move with you. Easily reconfigure your space as your needs evolve.

A Canvas for Any Style
Clean, smooth, and ready. The perfect foundation for Modern Minimalist, Island Luxury, Japandi, or Industrial design.

Ground Floor + Exterior Wall Structure

Shows the foundational connection between the ground floor and exterior walls. The multi-layer protective design strengthens moisture resistance, wind resistance, and structural stability — demonstrating the advantages of modular construction.

Tight Moisture Barrier, Completely Watertight

From the I-beam base to the wall waterproofing layer, multiple construction layers tightly block ground moisture and rainwater infiltration, forming a solid moisture barrier at ground level.

Rigid Connections, Strong Wind Resistance

Walls and the ground foundation are rigidly connected using standardized joints, effectively enhancing the building's lateral resistance and withstanding strong winds and ground settlement.

Modular Construction, Efficient & Precise

Components are prefabricated in the factory and quickly assembled on site, shortening the overall schedule while maximizing the precision and consistency of structural connections.

Roof Ceiling + Interior Wall Structure

Shows the integrated connection between the roof, ceiling, and interior walls. This system not only ensures structural stability through its core load-bearing members, but also delivers thermal insulation and soundproofing while meeting diverse interior finish aesthetics.

Light-Steel Truss: Core Load-Bearing Frame

High-strength light-steel truss framing serves as the primary load-bearing structure, evenly transferring roof loads to the walls and ensuring the stability and safety of the overall structure.

Composite Fill: Combined Insulation & Soundproofing

The truss cavities are filled with glass wool and other high-performance materials, forming excellent thermal and acoustic insulation layers that block heat loss and outside noise — enhancing comfort.

Roof + Exterior Wall Structure

Shows the complete construction sequence from the roof's exterior finish and insulation through the structural layer to the exterior wall. Scientific layering and material selection integrate waterproofing, insulation, and load-bearing into one system — fully safeguarding the safety and comfort of the building envelope.

Waterproof & Watertight

Multiple safeguards — completely watertight

Thermal Insulation

Warm in winter, cool in summer — superior energy efficiency

Stable Load-Bearing Structure

Reliable structure, longer service life

Bedroom Floor + Partition Wall (Bathroom)

Shows the floor and partition wall construction details for the bathroom's wet zone. The design focuses on long-term safety and durability — scientific layering and material selection address the waterproofing, slip-resistance, and moisture-control challenges of bathroom environments, ensuring a quality living experience.

All-Round Waterproofing

Multi-layer waterproof coating effectively blocks moisture infiltration

Safe & Slip-Resistant

High-friction floor tiles ensure safe footing in wet areas

Strong & Durable

Scientifically engineered layering extends overall service life

Bedroom Floor + Partition Wall (Standard)

This solution presents the standard floor and partition wall system for a typical bedroom. By combining an optimized light-steel floor deck system with high-density acoustic materials, the design ensures structural stability while significantly reducing impact and airborne sound transmission — improving comfort and privacy.

Light-Steel Floor Deck

Lightweight yet high-strength, combining excellent load-bearing capacity and impact resistance to keep the floor structure stable and durable.

Effective Soundproofing

Filled with professional damping and acoustic materials that block noise transmission, creating a quiet, comfortable indoor living environment.

Floor Ceiling + Interior Wall Structure

Concealed Utility Routing

Plumbing and electrical lines can be fully routed within the cavities of the light-steel framing for a completely concealed layout — keeping walls and ceilings clean and uncluttered.

Versatile Ceiling Designs

The ceiling structure reserves ample space for a wide range of design styles, and easily accommodates recessed lights, track lighting, and other fixtures.

Suited to Modern Renovation Needs

The modular connection method balances construction efficiency with design freedom, perfectly meeting the personalized fit-out standards of modern residential and commercial spaces.

Floor + Exterior Wall Structure

STRUCTURAL INTEGRATION OF FLOOR & EXTERIOR WALL

Shows the integrated connection between the floor and exterior wall. Scientific layering of the insulation and load-bearing structural layers achieves efficient coordination between the building envelope and the structural system — fully ensuring thermal insulation, waterproofing, moisture resistance, and structural stability.

Thermal Insulation

Multi-layer composite insulation design blocks thermal bridging and improves energy efficiency

Structural Synergy

Floor and wall load-bearing systems interlock tightly for stability and seismic resistance

Overall Performance

Multi-system integrated design safeguards building quality across its full lifecycle

Interior Floor + Interior Wall Structure
