Sitting with Nature — interactive outdoor shelter at Baxter Conservation Area
Installation Environmental Design Capstone — 2025–2026 Individual

Sitting with Nature

An interactive outdoor shelter that invites rest, play, and connection with the natural environment — designed for Baxter Beach within the Rideau Valley Conservation Authority. The project combines seating, sensory interaction, and environmental learning to enhance visitors' relationship with the site, while meeting the needs of a wide and diverse public.

Context
Rideau Valley Conservation Authority — Baxter Beach, real client
Materials
Steel structure, cedar cladding, recycled HDPE, powder-coated sheet metal, acrylic
Key Features
Bariatric seating, adjacent wheelchair space, lift-to-reveal sensory panels, interactive shelter

Developed through Carleton University's ConnectID programme (2025–2026), this capstone paired with a real client to reimagine outdoor seating at Baxter Beach.

Baxter Beach is a publicly accessible conservation area with a mix of visitors — families, elderly visitors, people with mobility aids, and children. The site sits within a conservation landscape, with sight lines across the river and surrounding trees forming a natural canopy.

A site visit revealed that existing seating was minimal and offered no shelter, no sensory interest, and no meaningful integration with the landscape. Visitors had few reasons to linger or engage with the environment beyond passive observation.

Defining the Problem

What's Getting in the Way?

Key challenges at Baxter Beach limit comfort, accessibility, and engagement with nature.

!

Unclear
Orientation

Visitors aren't sure where to go or what to expect on-site.

Limited
Accessibility

Many areas and amenities are difficult to access.

Not Enough Places
to Gather & Rest

Seating is limited and not suited for different seating types and spatial experiences.

Outdated Facilities
& Amenities

Outhouses and amenities are limited, hard to access, and need improvement.

Little Connection
with Nature

Opportunities for play, learning, and interaction with nature are limited.

Framing the Opportunity

Opportunities Driving the Proposal

Three directions shaped the proposal: creating playful nature-based encounters, supporting different ways of resting, and giving the site a clearer point of orientation.

Nature-Based Play

Open-ended interaction with natural materials can invite exploration, discovery, and informal learning.

Seating Variety

A range of seating types can support different postures, social situations, and comfort needs.

Landmark + Wayfinding

A distinct form can help visitors orient themselves while giving the site a recognizable place to gather.

Ideation

The flowing, arched form emerged early as the most promising direction — explored through sketches, physical mockups, digital modelling, and structural development.

Prototyping

Full-scale Experience Testing

Prototyping moved quickly to full-scale testing to evaluate human scale and the spatial quality of the shelter.

Sensory Element Prototyping

The lift-to-reveal leaf panels and tactile elements were prototyped separately — exploring materials, scale, and the legibility of the interaction for both children and adults.

Accessibility Feedback

Feedback from the Carleton Accessibility Institute directly shaped the proposal. Insights focused on seating ergonomics, mobility, sensory interaction, and accessible spatial layouts.

  • Provide a range of seating types and heights
  • Ensure adjacent wheelchair access within shared spaces
  • Design low-effort sensory interactions
  • Use stable, accessible ground surfaces
  • Make information visible and reachable

The Design

A continuous, arched shelter in cedar cladding and recycled HDPE, oriented toward the Rideau River landscape. The structure acts as both shelter and interface — its form shaped by the conservation landscape, its interior designed for rest, play, and learning.

Interaction and Experience

Visitors are drawn in by the form and oriented by the integrated Baxter info panel at the entrance. Inside, the shelter offers a place to sit and rest, look out across the landscape, and engage with the sensory play elements on the interior wall.

The lift-to-reveal leaf panels invite visitors to match silhouettes with local plant species — a tactile, educational interaction designed for children and adults alike. D-pull handles make each panel easy to grasp.

Accessibility Strategy

Seating icon

Seating

  • Primary seat height 430–485 mm
  • Armrests (rounded, 30–40 mm)
Mobility and inclusion icon

Mobility & Inclusion

  • Integrated wheelchair space (850 × 1390 mm min.)
  • Users remain within group setting, not separated
  • Covered area sized to accommodate mobility devices
Spatial experience icon

Spatial Experience

  • Flexible space allows mixed user participation
Sensory elements icon

Sensory Elements

  • Low-effort interaction (D-pull handles)
  • Sound elements carefully controlled
  • Avoid overstimulation; consider quiet use and overall context
Visual accessibility and information icon

Visual Accessibility & Information

  • High contrast between edges and surfaces
  • Sans-serif fonts, high contrast, legible text
Ground surface icon

Ground Surface

  • Firm, stable, slip-resistant surface
  • Suitable for wheeled mobility devices
  • Accessibility considered across entire approach, not just under structure

Material & Construction Logic

The structural system uses 2.5 × 2.5 cm and 2.5 × 4 cm steel tubes, connected by welded gusset plates and sleeve joints. This segmented approach allows the curved geometry to be fabricated in manageable sections, transported to site, and assembled precisely. Cedar cladding wraps the exterior for warmth and natural character. Recycled HDPE forms the weather protection shell on the rain side.

Making the Model

Sensory Interaction Models

The lift-to-reveal leaf panels were developed through multiple iterations — exploring material, the resistance of the lift mechanism, the depth of the reveal cavity, and how the leaf silhouette would be produced and finished.
