10 strategies for urban infill projects that integrate walkability, livability, green principles, and smart city technologies:

These focus on repurposing underused lots, parking areas, brownfields, or low-density blocks within existing cities to create dense, vibrant, sustainable neighborhoods.

1. Superblock-Style Pocket Neighborhoods

Transform clusters of 4–9 underused blocks into car-light or car-free “superblocks” by closing internal streets to through-traffic (limiting speeds to <10 km/h for access only). Reclaim space for wide pedestrian plazas, pocket parks, play areas, and cycle paths. Integrate smart sensors for real-time air quality, noise, and crowd monitoring, plus app-based booking for shared community spaces. This boosts walkability, reduces heat islands, improves biodiversity, and fosters community interaction (inspired by Barcelona).

2. Elevated Linear Parks Over Infrastructure

Build elevated or at-grade linear parks and walkways over existing highways, rail lines, or underused corridors (like New York’s High Line or Miami concepts). Incorporate native planting, bioswales, seating, and micro-mobility lanes. Add smart lighting, EV charging points, augmented reality historical overlays via apps, and solar-powered Wi-Fi kiosks. This creates safe, shaded pedestrian connections while adding green space and reducing urban heat.

3. Vertical Mixed-Use “Green Sponges”

On infill sites, develop mid-rise mixed-use buildings with stacked uses (ground-floor retail/cafes, mid-level housing/offices, upper-level green terraces). Design buildings as “green sponges” with living walls, rooftop farms, rainwater harvesting, and integrated bioswales at street level. Embed IoT for smart energy management, waste sorting, and predictive maintenance. This promotes 15-minute city access to daily needs on foot while maximizing density and greenery.

4. Adaptive Reuse with Sky Bridges and Courtyards

Convert old warehouses, factories, or parking structures into live-work-play hubs connected by climate-controlled or green sky bridges. Create internal green courtyards with communal gardens and playgrounds. Use smart city tech like occupancy sensors for dynamic lighting/HVAC and community apps for resource sharing (tools, cars, bikes). Enhances livability through social connectivity and walkable internal circulation.

5. Permeable “Green Streets” and Play Streets

Redevelop streets and lots with permeable pavements, rain gardens, tree canopies, and modular furniture that allows streets to close for play or markets on weekends. Integrate smart traffic calming (e.g., retractable bollards) and air-purifying plant installations. Apps can notify residents of events or real-time flood risk. This manages stormwater naturally, cools the area, and prioritizes pedestrians over cars.

6. 15-Minute Eco-Districts with Multimodal Hubs

Design compact infill districts where all essentials (groceries, schools, clinics, parks, work) are within a 15-minute walk. Centralize smart multimodal hubs with e-bike/scooter shares, EV pools, and real-time transit info displays. Surround with green corridors and urban orchards. Use data analytics to optimize services and reduce car dependency.

7. Biodome or Greenhouse Community Anchors

Incorporate mid-block biodomes or glasshouse structures for year-round urban farming, community events, and education. Link them via pedestrian greenways. Smart systems monitor climate, automate irrigation with harvested rainwater, and track produce distribution. This adds fresh food access, biodiversity, and iconic gathering spaces that improve livability.

8. Smart Green Corridors and Wildlife Bridges

Create interconnected green corridors along infill edges or former roads, planted with layered vegetation for cooling and habitat. Include elevated wildlife/pedestrian bridges where needed. Deploy sensors for biodiversity monitoring (cameras, sound) and citizen science apps. Combine with shaded walk/bike paths and benches with solar chargers. Reduces fragmentation and enhances ecological and human health.

9. Modular Micro-Housing with Shared Green Amenities

Use modular, flexible micro-units or co-living buildings on small infill parcels to increase housing density affordably. Pair with generous shared rooftop gardens, ground-level co-working, and tool libraries. Smart building management systems handle energy, security, and shared resource booking. This supports diverse demographics while keeping the area walkable and low-carbon. Example: Cophenhage uses stacked retired converted floating shipping containers built on the water for student housing.

10. “Under the Line” Multi-Level Activation

Activate spaces under elevated transit lines or overpasses with layered uses: ground-level markets/cafes, mid-level walkways with greenery, and upper-level solar canopies. Include interactive art, pop-up stages, and fitness zones. Integrate sensors for usage analytics and dynamic programming via digital signage. Turns dead space into vibrant, walkable destinations that boost local economy and safety.

These ideas emphasize mixed-use density, pedestrian priority, nature integration, and technology for efficiency/resilience. They draw from proven examples worldwide while allowing creative adaptation to local climate, culture, and regulations. Implementation benefits include lower emissions, better public health, economic vitality, and climate adaptation. Prioritize community input, equity (affordable housing), and phased development for success.

Neurodivergent (or neurodiversity-inclusive) standards for buildings

These focus on designing or retrofitting environments to better support people with conditions like autism, ADHD, dyslexia, dyspraxia, and other forms of neurodivergence. These address sensory processing differences (e.g., hypersensitivity or hyposensitivity to light, sound, textures, smells), cognitive needs (e.g., predictability, reduced overload), and preferences for choice, control, and calm.

Traditional accessibility standards (like ADA in the US or Part M in the UK) emphasize physical/mobility access. Neurodivergent design extends this to “invisible” or sensory/cognitive needs, often benefiting everyone through reduced stress and improved focus.

Key Standards and Guidelines

  • PAS 6463:2022 – Design for the Mind – Neurodiversity and the Built Environment (British Standards Institution): This is the most prominent formal guide, believed to be the first national standard specifically addressing neurodiversity in the built environment. It covers buildings, external spaces, public/commercial use, and residential settings.Core principles include clarity, comfort, control, and choice (often summarized as “clarity, control, and calm”). It provides recommendations on:
    • Lighting (adjustable, diffused, minimize glare/flicker; avoid harsh fluorescents).
    • Acoustics (sound absorption, reduced echo/reverberation, quiet zones).
    • Wayfinding and layout (predictable, intuitive navigation; clear signage with good contrast; reduced cognitive load).
    • Sensory zoning and materials (minimize visual clutter, strong odors, overwhelming patterns/textures).
    • Thermal comfort, air quality, and access to nature (e.g., pocket parks or quiet outdoor spaces for regulation).
    • Flexibility, stakeholder engagement (including lived experience), and safety features.
    It applies alongside standards like BS 8300 for broader accessibility.
  • ASPECTSS™ Design Index (Magda Mostafa): An evidence-based framework specifically for autism-friendly design, usable as an assessment and development tool. Key criteria:
    • Acoustics: Control noise, echo; vary by activity.
    • Spatial Sequencing: Logical flow and predictability in layouts.
    • Sensory Zoning: Group spaces by stimulus level (high/low) with transitions.
    • Transition Zones: Areas to recalibrate senses.
    • Safety: Rounded edges, etc.
    • Quiet/Withdrawal Spaces: Low-stimulation respite areas.
    • Compartmentalization: Clear, single-function sensory environments.
  • Other Resources:
    • Stimpunks Neurodivergent Design Standards: Defines levels (ND-1 Friendly, ND-2 Supportive, ND-3 Native) emphasizing proactive design for attention, sensory safety, bodymind breaks, and reduced masking.
    • RIBA Inclusive Design Overlay, HOK guides, and various placemaking or campus-specific frameworks.
    • Emerging efforts (e.g., in Australia) for national neuro-inclusive standards.

Common Design Recommendations

These draw from the above and broader best practices:

  • Sensory Comfort — Adjustable/dimmable lighting (natural + warm LEDs); sound-absorbing materials and quiet zones; neutral colors, minimal patterns/clutter; good ventilation and odor control.
  • Predictability & Navigation — Clear, consistent wayfinding; logical spatial flow; visual cues.
  • Choice & Flexibility — Variety of spaces (focus pods, collaborative areas, sensory rooms); movable furniture; options for privacy or stimulation.
  • Regulation Support — Access to nature, movement-friendly areas, bodymind break spaces.
  • Universal Benefits — Many features (e.g., better acoustics, less clutter) improve usability for all users, including those with dementia or migraines.

Implementation is still evolving and not yet mandatory in most building codes (e.g., not fully integrated into US ADA or equivalent everywhere). Best results come from co-design with neurodivergent people.

For practical application, consult the full PAS 6463 document (available via BSI), ASPECTSS resources, or engage specialists. Architects and organizations like Gensler, Stantec, or neurodiversity-focused firms increasingly incorporate these principles. If you’re designing, renovating, or advocating for a specific building type, more tailored advice is possible with additional details.

Orla Studios Guide to Designing with Mass Timber

At Orla Studios, we see mass timber as more than a building material—it is a framework for designing sustainable, human-centered architecture. Our architectural project, the Mass Timber Winery, now under construction in Napa Valley, embodies the principles and best practices of designing with this extraordinary material. Below, we share an in-depth guide to approaching mass timber design, from concept to construction.


Understanding Mass Timber

Mass timber is an umbrella term for engineered wood products created by layering and bonding smaller wood elements into large structural components. The main types include:

  • Cross-Laminated Timber (CLT): Layers of lumber stacked at right angles and glued together to form rigid panels ideal for walls, floors, and roofs.
  • Glue-Laminated Timber (Glulam): Boards bonded lengthwise to form strong beams and columns.
  • Nail- or Dowel-Laminated Timber (NLT/DLT): Lumber fastened together without adhesives, creating panels suited for decking and floors.

Each type has specific advantages, and successful projects often combine several systems.


Principles of Designing with Mass Timber

  1. Early Integration of Structure and Architecture
    Mass timber is most successful when structural and architectural design proceed hand in hand. The size and spacing of beams, columns, and panels dictate interior proportions and aesthetics. Unlike steel or concrete, mass timber structure is often left exposed, so early design decisions directly shape the building’s character.
  2. Modularity and Prefabrication
    Mass timber panels and beams are fabricated off-site with precision CNC cutting. This allows for rapid assembly, but it requires careful planning during design. Dimensions should align with manufacturing standards, transportation limits, and crane capacities. Modular thinking reduces waste and speeds up construction.
  3. Fire Safety Design
    Despite being wood, mass timber achieves robust fire performance. Panels char at a predictable rate, forming a protective layer that insulates the structural core. Designers must account for sacrificial charring when sizing beams and panels, and coordinate closely with fire consultants and code officials.
  4. Seismic and Structural Performance
    Timber’s lightness and flexibility reduce seismic loads compared to concrete. Connections—steel plates, dowels, and screws—become critical elements of design. Careful detailing ensures both strength and ductility, particularly in taller structures or those in earthquake-prone regions.
  5. Acoustics and Vibration Control
    Mass timber’s lightness can present challenges with sound transmission and floor vibration. Solutions include layering materials (e.g., topping slabs or acoustic mats), designing for thicker panels, and integrating sound-absorbing finishes in interiors.
  6. Moisture and Durability
    Protecting timber from prolonged moisture exposure is essential. Overhangs, rainscreens, and controlled detailing at joints prevent water infiltration. During construction, weather protection measures (temporary roofs, membranes) safeguard panels before the building envelope is complete.
  7. Mechanical, Electrical, and Plumbing (MEP) Coordination
    Because panels are prefabricated, openings for ducts, conduits, and fixtures must be carefully planned and cut before delivery. Close coordination with engineers ensures services are integrated cleanly, avoiding costly on-site modifications.

Design Opportunities with Mass Timber

  • Exposed Beauty: Unlike steel or concrete, mass timber structure is celebrated visually. Beams, columns, and ceilings can remain exposed, reducing the need for finishes and creating warm, natural interiors.
  • Biophilic Design: Natural wood enhances human well-being by connecting occupants to nature, lowering stress, and improving productivity.
  • Hybrid Systems: Many projects combine mass timber with steel or concrete. For example, concrete cores may house elevators and stairs while timber spans large open areas. This hybrid approach maximizes structural efficiency.

Case Study: Our Mass Timber Winery

Our  Winery in Napa Valley demonstrates how these principles come together:

  • Open Production Spaces: Long-span glulam beams create column-free zones for winemaking, while CLT panels form insulated, breathable roof structures.
  • Hospitality and Experience: In the tasting room, exposed CLT ceilings and timber columns bring warmth and intimacy, reinforcing the winery’s connection to the vineyard landscape.
  • Sustainability in Practice: The winery leverages the carbon-sequestering qualities of timber, combined with passive cooling strategies and rainwater management systems, to minimize environmental impact.
  • Craft and Precision: Every joint and detail has been coordinated digitally before fabrication, ensuring a seamless on-site assembly and minimal waste.

Looking Ahead

Designing with mass timber requires a mindset shift—from linear construction sequencing to integrated, collaborative design. Architects, engineers, manufacturers, and builders must work as one team, with sustainability and precision at the core.

At Orla Studios, we are committed to advancing mass timber design across residential, commercial, and cultural projects. Our Winery project illustrates what is possible: architecture that is sustainable, resilient, and deeply connected to place. For us, mass timber is not just a material—it is a philosophy of building responsibly for the future.
