ARCHITECTURE PORTFOLIO

Rachel Ran Yan selected works

As a recent Master of Architecture graduate from the University of Toronto, bring a strong foundation in spatial design, technical documentation, and interdisciplinary collaboration. My experience spans residential, educational, and public projects, from new construction to housing renovation and heritage restoration.

Alongside design practice, have contributed to the delivery of commercial renovation projects, coordinating with contractors, consultants, and trades to resolve on-site issues and support project management from design development through construction. This experience has strengthened my understanding of how architectural ideas translate into built reality.

Having worked with diverse teams in international settings, value open communication, critical thinking, and design that is both responsive and forward-looking.

My portfolio bridges traditional and emerging approaches. I work through conventional architectural methods - drawing, model-making, and spatial composition - while also exploring generative systems, parametric design, and AI-assisted optimization. My research integrates computational strategies with contextual thinking to support more adaptive and responsive environments.

Yellow Invitation

Project Type: Circular Library|Mixed-use Community Hub

Focus: Mass Timber|Sustainable Design

Tool: Rhino|Grasshopper|Ladybug|Climate Studio|Life Cycle Assessment|Revit|Lumion|Enscape

The Yellow Invitation is a comprehensive design for a circular library and community hub along the Gowanus Canal, conceived as a social condenser to foster exploration and community engagement. At its core is a vibrant yellow staircase system, a dynamic spatial invitation that encourages spontaneous movement and discovery through layered mass timber volumes. Transitional spaces and an adaptable perforated zinc façade further enhance spatial connectivity, daylighting, and environmental performance. Driven by a commitment to sustainability, the project integrates passive conditioning strategies, low-carbon materials, and life-cycle considerations, aspiring to serve the evolving needs of its community over a century-long lifespan.

Circular Store Reception

The project is located along the eastern edge of the Gowanus Canal in Brooklyn, New York, at the intersection of light industrial zones to the south and dense residential neighborhoods to the north and west.

The surrounding area is marked by diverse building typologies including low-rise townhouses, public housing, industrial warehouses, and emerging green infrastructure. This urban mix results in a highly dynamic social environment, drawing a wide range of users including residents, workers, and visitors.

Further Studies indicate that the site and adjacent areas are at significant risk of flooding, especially under 4–6 ft scenarios. Solar studies and sectional diagrams further reveal complex topography and layered urban infrastructure, including elevated highways and railways.

FUTUREGREENWAY

This project is envisioned not only as a flexible container for an unconventional mix of programs, but more importantly, as a social condenser that fosters spontaneous exploration and unexpected encounters. It is structured around three elements: a regular mass timber frame, a vivid yellow circulation system embedded within it, and a muted perforated zinc façade wrapping the volume.

Each atrium anchors a different spatial moment and reflects its surrounding program. The first atrium, located near the entrance, spans two stories and is enclosed by three sides of glass walls. It creates a strong sense of openness, directly connecting the building interior with the street and canal. As the circulation moves upward to Level 2, the atrium continues, separating the café and workshop zones through a more transparent and soft-edged boundary. By Level 4, the third atrium is defined by increased enclosure as surrounding programs require more privacy and controlled access.

Monthly Heat Flow

The embodied carbon diagram reveals that the façade contributes significantly to the building’s overall carbon footprint. However, zinc was selected for its high durability, resistance to corrosion in the canal’s humid environment, and minimal long-term maintenance needs. Many of the materials used, including zinc, mass timber, and stone wool insulation, are recyclable or renewable, reducing the building’s lifecycle impact.

Cooling peaks in summer and heating in winter, but overall demand stays steady. Internal heat gains offset winter heating needs, while passive strategies like spring/fall ventilation and skylight daylighting reduce cooling and lighting demands, leading to lower overall system loads.

Flood-Resistant Column Base

Each column base is encased in concrete to improve stability and durability. This detail also suggests protection against future flooding or surface water exposure, grounding the lightweight frame in a more resilient base.

Beams Running in a Single Direction

This layout was developed after calculating optimal beam spans and cross-sections, ensuring structural integrity while preserving generous floor heights. It also supports skylight integration at each floor, allowing natural light to reach deep into the interior.

Regular Structural Grid

A regular grid of columns establishes a clear structural order and supports an open, flexible layout. Its repetitive logic allows the building to adapt over time while reinforcing a modular spatial system.

Steel-Reinforced MEP Structure

Steel joists are used only at the MEP room to support heavier equipment loads and larger spans. This localized reinforcement distinguishes the service zone from the lighter structural system used throughout the rest of the building. Concrete Core The

Cube Village

Project Type: Community Renewal

Focus: Community Activation|Adaptive Reuse|Space Typology

Tool: Rhino|Sketch Up|AutoCAD|Grasshopper|Enscape

Regent Park, Toronto’s largest and oldest social housing community, has long been home to a diverse population while facing persistent challenges of crime and social fragmentation. Guided by the City’s vision for renewal, this project introduces lightweight, modular structures atop existing buildings, aiming to rejuvenate the neighborhood while respecting its architectural fabric. New mixed-use volumes activate the community with social and commercial opportunities, while open spaces and transitional zones foster interaction and public life. A structural support system integrates circulation and connectivity, enabling a flexible and adaptive model for modular urban infill and community regeneration.

Located in downtown Toronto, Regent Park is the city’s oldest social housing community and has undergone decades of redevelopment to address its historical isolation and socio-economic challenges. The neighborhood is home to many children, seniors, and individuals living alone, with high rates of disability and social disconnection. These conditions highlight the need for flexible housing and shared spaces, guiding the project’s focus on inclusion, connectivity, and community-oriented design. Site analysis reveals an uneven distribution of services in Regent Park. While restaurants are common, healthcare facilities, gyms, and daycare spaces are scarce, despite high proportions of residents with disabilities, mental health needs, and a large youth population. Most amenities cluster along the southern edge, leaving the north under-served. In response, the project focuses on this area, introducing programs based on existing urban patterns. Commercial spaces are placed near transit hubs, while larger community facilities are located near parking areas to improve accessibility and community well-being.

Circulation is organized for four user groups: local residents, non-local customers, visitors, and office staff. Each follows a distinct path to reduce conflict and improve efficiency. Nonlocal users remain near the perimeter, where commercial programs are located close to bus stops.

Local residents have direct access to private gardens and shared amenities. Offices are positioned near the transport hub, allowing staff to reach workspaces quickly without disrupting other users.

Civic Sail

Project Type: High-Rise Architecture|Civic Landmark

Focus: Mixed-Use Vertical Community|Programmatic Integration|Democratic Space|Cultrual Narrative

Tool: Rhino|AutoCAD|Grasshopper|Enscape|Twinmotion

The Civic Sail is a high-rise design for Qingdao’s waterfront, conceived as a new civic landmark that reclaims the city’s skyline from colonial architectural symbols. Historically, the city’s most prominent landmark was St. Michael’s Cathedral, a relic of German colonial occupation. This project proposes a contemporary counterpoint, a dynamic tower shaped like a sail, celebrating Qingdao’s maritime culture while adding a new civic identity. The design compresses diverse urban functions within a single vertical structure, challenging traditional skyscraper hierarchies. Instead of vertically segregated programs, the tower distributes functions horizontally and spatially across its structure, promoting accessibility and public engagement throughout. This strategy transforms the high-rise into a truly democratic space where citizens can engage with the building at every level.

Qingdao is a major tourist destination in China, yet its most iconic landmark remains the German-built cathedral, a reminder of how the city’s image is still shaped by its colonial past. This project proposes a new civic landmark: an architecture of democracy that challenges colonial spatial dominance and eclaims public identity through shared space.

V.S

Conventional high-rises reinforce spatial privilege, reserving the best views and amenities for a few. This project dissolves that hierarchy by distributing residential, office, public, and commercial programs across all levels, reimagining the tower as an egalitarian urban structure.

Located on Qingdao’s eastern waterfront, the project aligns with the city’s long-term coastal expansion. The tower emerges from three basic volumes that are fragmented and recombined, reflecting the strategy of distributing programs across levels. Its sail-like form houses commercial space and a ferry terminal at the base, with diverse programs above and a sea-facing sky theatre at mid-height. The façade uses high-performance terracotta cladding, chosen for durability in Qingdao’s coastal climate. Its pattern intensifies from bottom to top, responding to atmospheric conditions while expressing a sense of vertical growth.

The façade does not fully enclose the building; its openings define shifting boundaries between interior and exterior spaces, balancing privacy inside with openness and views outside.

Materials including concrete columns, terracotta and metal panels, and glass glazing shape the building’s expression. Balcony orientation also affects privacy: inward-facing balconies create more visual connection, while outward-facing ones offer greater privacy.

Evolving Commons

Project Type: Data-Informed Generative Architecture

Focus: Multi-Objective Optimization|Parametric Design|Computational Design

Tool: Rhino|Grasshopper|Ladybug|Discover|Midjourney|Stable Diffusion|ControlNet|Nano Banana

This project explores a multi-objective optimization (MOO) workflow to inform the earlystage design of a community hub. Guided by diverse stakeholder needs, the process defined three primary goals: maximizing usable floor area, enhancing building sunlight exposure, and increasing spatial diversity. Parametric modeling and performance-based simulations guided the generation and evaluation of over 200 design iterations. Six optimal solutions were identified through quantitative analysis, with final selections refined through an iterative visualization process to explore spatial qualities and design expression. The project demonstrates how optimization and data-informed methods can enrich design exploration and support adaptive, responsive architectural outcomes.

FUTUREGREENWAY SUBWAYSTATION

The site sits along the Gowanus Canal in Brooklyn, surrounded by residential areas, light industry, a future greenway, and a subway station, attracting diverse users from families to artists and visitors.

To address these varied needs, the project applies a multiobjective optimization approach. Stakeholder analysis identified three key groups - families with children, local artists, and social visitors, whose spatial and functional preferences informed the design goals and key spatial decisions.

To address stakeholder needs, three goals were defined: maximizing floor area, increasing sunlight exposure, and enhancing spatial diversity. These were translated into measurable parameters - usable floor area, sunlight duration, and perimeter complexity - and embedded into the computational workflow.

Using Grasshopper, the site is subdivided into parametric cells to generate multiple building volumes. Each iteration is evaluated through simulations, including Ladybug for environmental analysis. Results are then processed by the optimization tool Discover, which identifies high-performing solutions through multi-objective evaluation. Iterations evolve across generations, using top results to refine subsequent designs.

rate. Scatter plots compare performance across three goals: floor area, sunlight hours, and spatial diversity.

Each graph maps different metric combinations, revealing trade-offs between design options. As generations evolve, results cluster around stronger solutions, showing how the optimization process progressively identifies higherperforming outcomes based on spatial quality and environmental performance.

Among the 210 generated iterations, six designs emerged as optimal when evaluated across all three performance goals: floor area, sunlight hours, and spatial variety. The scatter plots on the left illustrate how these options perform relative to one another under different metric combinations. From this group, three representative designs - #13, #24, and #99 - were selected for closer comparison, based on their balanced performance and distinct spatial strategies. Each 3D diagram is paired with a sunlight analysis to visualize façade exposure and guide refinement. While all three offer strong quantitative outcomes, the final selection was informed by architectural judgment. Design #13 was ultimately chosen for its overall clarity and spatial potential. Its central courtyard enhances daylight and airflow, provides a clear organizational core, and creates a welcoming open space within the dense urban fabric. The overall massing supports both visual continuity and future flexibility, making it a compelling foundation for further development.

A hybrid visualization workflow combines parametric 3D modeling with AI image generation to support early exploration of massing and landscape design. Rather than detailing interiors, the process tests how large-scale forms interact with surrounding environments, seasons, and public spatial atmospheres. Precedent images first establish visual tone, materiality, and environmental character, informing prompt templates paired with Rhino massing models. Using ControlNet with Stable Diffusion, base geometry guides the AI generation process, maintaining spatial consistency. Through iterative prompt adjustments - refining lighting, weather, vegetation, and atmosphere over 200 visualizations were produced. The matrix illustrates three scenarios: aerial views, winter plazas, and a central courtyard. These generative renderings function as a design feedback tool, helping evaluate massing, spatial edges, and landscape integration during early conceptual development.

The Umbrellas

Project Type: Kinetic Architecture|Responsive Pavilion

Focus: Movement Manchnism|Parametric Design|Modular Assembly|Flexible Space Programming

Tool: Rhino|Grasshopper|Ladybug|Kangaroo|Karamba|Enscape

This project builds on the movement and mechanism principles of the Medina umbrella, developing a new modular unit capable of creating dynamic shading and adaptable space. The system uses simple operable mechanisms combined with parametric design to enable various spatial configurations which are flexible in size, density, and form. Designed for temporary urban events, the modules can be quickly reassembled to host different programs, from conference spaces and markets to exhibitions and performances. Through this adaptable system, the project explores how kinetic structure and parametric control can bring responsiveness and versatility to public space.

In the Medina courtyard of the Prophet’s Mosque, large retractable umbrellas provide shade for the open plaza through a sophisticated folding structural system. The frame movement is driven by an electronic motor inside the central pole, allowing rings to move vertically and trigger the folding and unfolding of the structure. Inspired by this mechanism, the project studies its kinetic logic and adapts it into a prototype.

The design explores a kinetic shading structure formed by hinged and supporting arms connected to fixed points along a central pole. Vertical movement along the pole is converted into rotational motion, allowing the canopy frame to fold and unfold in a coordinated sequence while maintaining structural stability. The canopy consists of tensile fabric panels supported by a lightweight metal frame. An electric motor inside the mast drives a threaded shaft that moves a sliding ring vertically, activating the hinged arms and deploying the canopy. This mechanism enables the structure to transform between a compact closed state and a fully extended shading system for adaptable outdoor use.

Passive Arms

Hinged at the outer end of arms, defining the opening shape of the canopy.

The Inner Arm, or the primary member, slightly moves up on the pole to promoting the unfolding of the umbrella; it simultaneously rotates outwards (clockwise) around the joint.

To open, the Upper Support Member moves down on the pole and simultaneously rotates slightly outwards (counterclockwise) around the joint. The Outer Arm do not move spontaneously. Its motion follows the movement of the Lower Support Members and the Inner Arm; it opens when the Lower Support Member opens, and rotates around the linkage with the Inner Arm.

Structure

Opens both sides, the motion of each arm is defined by a total of four sliding and rotating units.

Since the opening angles are different, the inward supporting arms feature different lengths of sliders.
