Spatial Context: How Active Retech Enhances Architectural Proposals With XGRIDS 3D Spatial Capture

Case Studies2026.10.125 min read

Active Retech brings real-world spatial context into residential design proposals using the XGRIDS Lixel K1 handheld scanner and Unreal Engine.

For residential design and renovation projects, understanding an existing property and its surrounding environment is a critical first step in developing a proposal. Traditional documentation methods—such as site photographs, floor plans, and physical measurements—can document a space, but they may not fully convey how a proposed design visually relates to its real-world neighborhood.

Japanese company and XGRIDS partner, Active Retech is integrating 3D spatial capture into its residential pre-design workflow using the XGRIDS handheld SLAM scanner Lixel K1. By creating photorealistic 3D representations of existing site surroundings, Active Retech brings realistic spatial context into the early stages of its design and proposal workflow.

The Challenge: Capturing Authentic Site Context

Before adopting XGRIDS, Active Retech sometimes used simplified white-box CG models to represent the environment surrounding a proposed residential project. However, this previous approach presented clear challenges:

Deviation From Reality: White-box models could result in representations of the surrounding environment that differed from reality.
High Production Cost: Recreating the surrounding environment entirely in detailed CG required a significant amount of time and budget.
Visualization Gaps: It was difficult to accurately reproduce the atmosphere of the site using CG alone.

To overcome these limitations, Active Retech sought a solution that would allow anyone on the team to easily capture realistic spaces with good visual quality. The company incorporated the XGRIDS 3D spatial representation directly into its pre-design workflow, using the captured environment as an accurate spatial reference for design iterations.

“What impressed us most was that we were able to reduce the amount of work involved while achieving a higher level of realism. Showing the before-and-after differences made the proposed changes much easier to communicate and understand.”

The Solution: Seamless 3D Capture & CG Integration

For this project—centered on a detached single-family house—Active Retech used the XGRIDS Lixel K1 handheld scanner to capture the surrounding environment of the planned construction site.

The team’s workflow follows four steps:

On-Site Environment Capture → 3D Environment Generation → Unreal Engine Integration → Proposal & Design Review

Operational Breakdown: Lixel K1 Capture to Unreal Engine Workflow

Hardware Used: XGRIDS Lixel K1.
On-Site Capture: Completed by 1 operator in approximately 10 minutes.
CG & Integration: While discussions and iterations on the CG house model took several weeks, combining the CG model with the captured 3D environment in Unreal Engine took approximately 3 days.

By placing the proposed CG house directly into the captured real-world environment, Active Retech could check how the proposed structure would look from adjacent roads and evaluate actual circulation through the site before construction began.

The Impact: Smarter Design Reviews

Integrating XGRIDS solutions fundamentally improved how Active Retech documents environments and communicates proposals:

Higher Efficiency & Realism: Reduced manual modeling work while achieving superior environmental realism.
Better Spatial Evaluation: Designers could analyze sightlines from surrounding roads and test movement through the site directly in Unreal Engine.
Extended Contextual Capture: In other projects, Active Retech has also captured the walking route from a local train station to the site, giving clients an authentic feel for the location’s atmosphere prior to construction.

“Because the proposed design could be placed directly into the actual environment, we were able to check how it would look from the road and evaluate the actual movement and circulation through the site.”

Looking Ahead: Extending Spatial Intelligence in AEC

The success of the Active Retech project signifies a broader shift in how AEC professionals interact with physical environments. Spatial capture is no longer just a standalone visualization tool or a niche post-production luxury; it has become a fundamental, workflow-ready bridge that connects physical site reality with digital architectural creation. Looking ahead, Active Retech plans to explore XGRIDS applications beyond residential design, including planning parking layouts and signage placement for new store projects, as well as using spatial capture to better understand environments across aerial, ground-level, and indoor spaces.

Homebuilders, architects, and real estate professionals can turn an entire physical space into a detailed 3D digital environment that can be explored remotely, making it easier to present a proposed project within its actual surroundings and visualize how the finished result will look before construction begins. The same capability can also be applied to homes, stores, and other properties before renovation or demolition, preserving the space in 3D along with its spatial layout, visual details, and overall character. In this way, a physical environment can remain accessible as a digital space even after the site itself has changed.

The convergence of spatial capture and digital design is opening a new path for how the built environment is conceived, planned, and brought to life. By making high-precision spatial capture accessible and embedding real-world context directly into CG workflows, XGRIDS is helping bridge the gap between physical space and digital design, giving architects, designers, and AEC professionals a more accurate foundation for understanding existing environments and imagining what comes next. As these capabilities extend into broader AEC and real estate applications, XGRIDS is building toward a future in which spatially accurate, context-rich digital representations become a fundamental layer of the design process.
