Case Study : Hotel Renderings for Westin Vacation Club

Westin Vacation Club, Charleston, South Carolina

3D Hotel Visualization Supporting Architectural Design Validation and as a tool to win Formal Approvals for a ground-up hospitality development.

Overview

Vanrooy Design, a hospitality-specialized architectural and interior design studio based in Los Angeles, engaged NoTriangle Studio to produce a comprehensive suite of technically precise 3D renderings for the Westin Vacation Club development in historic Charleston, South Carolina.

This was not a conventional hotel marketing visualisation assignment as it required immersive, decision-ready imagery that needed to integrate directly into an active architectural workflow supporting design development, client reviews, and formal approvals with precision and technical clarity.

Rather than producing visual assets solely for presentation purposes, NoTriangle’s deliverables and 3D Rendering process served as an active design evaluation tool, providing a decision-support system that allowed stakeholders to thoroughly review, question, and validate the design before construction.

Project scope included:

60,696 sq. ft. ground-up hospitality development
50 guest rooms across 21 unique layouts
Public and shared amenity spaces
Custom environmental graphics
Interior concepts informed by Charleston’s historic Southern character

The visuals and process were a critical approval tool, providing clarity and enabling the project to advance into construction confidently.

Client Background

Vanrooy Design specializes in creating highly crafted hospitality and residential environments, translating layered architectural concepts into refined, buildable spaces that elevate everyday experience.

Their client, Westin Vacation Club (part of Marriott Group), commissioned a ground-up hospitality development that blends Charleston’s historic architectural character with Westin’s contemporary wellness-oriented global brand standards.

Rooted in Greek Revival and Victorian influences, the design reflects Charleston’s romantic historic character, thoughtfully calibrated to meet the operational demands of a contemporary hospitality development where guest experience is paramount.

Visualization Requirement

With 21 unique room types, layered material palettes, and custom-designed public spaces, Vanrooy Design required a visualization partner capable of delivering hotel 3D interior rendering that was both technically accurate and approval-ready.

The visuals needed to function as design-validation tools, supporting stakeholder alignment and brand approval—rather than acting as standalone hotel marketing imagery.

This is where NoTriangle Studio became an integral part of the design and approval process.

The Challenge

Working directly with architects introduces a fundamentally different set of requirements than traditional hotel video marketing or promotional visualization.

Here, the goal was not storytelling for sales—but precision, continuity, and support for active design decisions.

Key challenges included:

Seamlessly integrating Revit, AutoCAD, and SketchUp without disrupting the design pipeline
Managing multiple design revisions to refine details of materials and FFE
Maintaining technical accuracy across uniquely designed interior amenity areas and hotel guest-room types
Delivering consistent realism across interior spaces, bespoke joinery, lighting styles, and detailed finishes
Aligning deliverable production timelines with formal client review and approval dates

IIn this context, the interior hotel visualizations transcended conventional marketing assets and became integral, functional tools that directly influenced the final design and accelerated approvals.

Our Approach

NoTriangle Studio applied an architecture-first visualization workflow – prioritizing technical accuracy, transparent collaboration, and design clarity over simple presentation assets.

1. Architectural Intent Alignment

Before modeling began, we reviewed:

Design intent presentations
Construction documentation
FF&E schedules
CAD drawings
Revit and SketchUp models
Westin brand guidelines

This ensured we understood not only how the spaces should look, but how they were meant to function—supporting operational flow, brand standards, and approval requirements.

2. Technical Integration With the Design Workflow

The client asked whether our workflow could accommodate multiple source formats, as design information would be shared across Revit, SketchUp, and AutoCAD throughout the project. Given the evolving nature of the development, flexibility was essential.

NoTriangle adapted its pipeline to work seamlessly with all provided formats, leveraging each platform for its strengths:

SketchUp – Supported rapid iteration of interior layouts, FF&E placement, and design detail refinements
Revit and AutoCAD – Used to verify spatial logic, dimensions, and architectural intent, ensuring technical accuracy
Production Environment – All geometry was consolidated and refined, ready for final lighting and material application

This flexible approach allowed production to move forward quickly and maintained alignment with the latest design decisions, and reduced approval risk – critical for a hospitality project with multiple highly detailed amenities and a diverse array of room types.

3. Iterative Design Collaboration

Because the visuals were embedded in the approval process, we structured the workflow to support refinement:

Multiple camera views to evaluate spatial hierarchy
Progressive material and lighting refinement to align with the design vision
Revision-ready models for efficient updates of details as they evolved
Scheduled progress reviews
Consolidated feedback cycles

This allowed Vanrooy’s team to present current, accurate visuals during client and brand meetings – supporting swift and confident decision-making throughout the process.

4. Photorealistic Execution

Once all design details were locked-in and approved, we moved into full production, including:

Adding lighting accurate to the Charleston locale
Refining high-fidelity materials (wood, textiles, stone, glass)
Creating an atmosphere that aligned with Westin’s wellness-focused brand
Ensuring consistent visual language across all spaces

The 3D interior renderings of all hotel spaces progressed through approvals without major revisions, reflecting strong alignment and disciplined execution from the project kickoff.

Outcome

Client & Brand Approval Secured -Visuals supported full approval through Westin’s formal review process.
Project Advanced to Construction – The development is now under active construction.
Reduced Revision Cycles – Integrated workflows minimized rework on a 60,000+ sq. ft. hospitality project.
Strengthened Architectural Partnership – Vanrooy Design cited responsiveness, clarity, and technical understanding as key reasons NoTriangle’s visuals functioned as key decision tools, rather than mere presentation imagery.
