Short answer

When designing small campus courtyards, opt for varied plant heights and irregular arrangements to maximize their restorative and healing benefits for users.

Field: User-Centred Design
Source: Sustainability (2023)
Method: Mixed-methods (quantitative scales and qualitative semantic differential)
Evidence: Strong effect

Designers can improve the perceived healing effects of small campus courtyards by incorporating varied plant heights and irregular layouts, which better capture user attention and create a more restorative environment. This user-centred design research insight is drawn from a 2023 study published in Sustainability. Using Mixed-methods (quantitative scales and qualitative semantic differential), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing small campus courtyards, opt for varied plant heights and irregular arrangements to maximize their restorative and healing benefits for users.

Irregular planting and taller vegetation enhance campus courtyard restorative qualities.

Sustainability · 2023

Key Findings

01Vegetation at or above human visual height (trees, shrubs) yields better healing effects than lawns.
02Irregular plant layouts are perceived as more aesthetically pleasing and provide better light, aiding attention diversion from stress.
03User preferences for activity space are not dictated by the scale of the space itself.
04Abstract qualities like 'perceived quality' and 'experienced quality' are key indicators of a courtyard's healing atmosphere.

Application

Design takeaway

When designing small campus courtyards, opt for varied plant heights and irregular arrangements to maximize their restorative and healing benefits for users.

How to apply

When designing or renovating small urban green spaces, incorporate a mix of trees and shrubs with varied, non-uniform planting patterns. Pay attention to the overall sensory experience and atmosphere created by the landscape.

Project actions

01When evaluating existing spaces, consider both objective landscape features and subjective user perceptions.
02Use established scales like PRS and SD to quantify user responses, but also consider qualitative observations.

Method & Evidence

AimHow do specific landscape elements within small campus courtyards influence their perceived healing and restorative qualities?

MethodMixed-methods (quantitative scales and qualitative semantic differential)

ProcedureParticipants evaluated small campus courtyards using the Semantic Differential (SD) method to gauge aesthetic and atmospheric qualities, and the Perceived Restorative Scale (PRS) to measure restorative potential. Plant characteristics and layout were analyzed in relation to these evaluations.

ContextCampus courtyards in high-density urban environments

Variables

IV["Plant height (low vs. human visual height)","Plant layout (monotonous vs. irregular)"]

DV["Perceived healing effect (measured by SD method)","Perceived restorative potential (measured by PRS)"]

CV["Courtyard scale (small)","Campus setting (high-density)"]

Strengths & Limitations

Strengths

+Utilizes established psychometric scales (SD, PRS) for quantitative evaluation.
+Addresses a specific, under-researched niche (small campus courtyards).

Limitations

The specific types of plants and the exact dimensions of the courtyards studied might not be universally applicable. User demographics and prior experiences could also influence results.

Reliability & validity

The use of validated scales (SD and PRS) contributes to the reliability and validity of the measurements of perceived restorative qualities. However, the specific context of campus courtyards might limit generalizability, affecting external validity.

Think critically

To what extent do cultural differences in aesthetic preferences or the perception of nature influence the effectiveness of these design strategies in different global contexts?

Design Principles

"In constrained urban environments, landscape design should leverage plant diversity and spatial arrangement to optimize psychological restoration and stress reduction."

Understanding how specific landscape features influence psychological well-being is crucial for designing spaces that actively contribute to stress reduction and mental restoration. This insight helps create more effective therapeutic environments within often constrained urban settings.

What This Means for Your Design

To make a small campus garden feel more relaxing and healing, use taller plants like bushes and trees, and plant them in a natural, not too neat, way. How big the open space is doesn't matter as much as how the plants make you feel.

Paragraph starter

Research indicates that the restorative and healing qualities of small campus courtyards are significantly influenced by landscape design choices. Specifically, the inclusion of vegetation at or above human visual height, such as trees and shrubs, and the use of irregular planting layouts, have been shown to enhance these effects by improving aesthetic appeal and diverting attention from stressors. These findings suggest that designers should prioritize diverse plant heights and non-uniform arrangements to create more effective therapeutic environments within constrained urban settings.
