Embracing Nature in Low-to-Mid-Rise Design: Insights from the NSW Housing Pattern Book Landscape Design Guide

Here at SN Architects, we believe that the spaces between our buildings are just as important as the buildings themselves. The newly released NSW Housing Pattern Book Landscape Design Guide (July 2025) strongly reinforces this philosophy. Developed as a companion to the NSW Housing Pattern Book, the guide provides practical, performance-based advice for creating beautiful, sustainable, and low-maintenance gardens for low- and mid-rise homes.  

Operating under the guiding principle of "Designed for people, powered by nature," this resource is a call to action to build resilient landscapes that nurture both communities and the environment. Below, we break down the most impactful strategies from the guide that will shape the future of residential landscape architecture in NSW.  

1. Prioritizing Tree Canopy and Deep Soil

One of the most critical elements of modern landscape design is integrating sufficient tree canopy to provide shade, cool the environment, and support local wildlife. The guide establishes clear minimum requirements for tree canopy and deep soil areas based on the site size and development type.  

Here is a summary of the targets for terraces, semi-detached homes, and row homes:  

Site Area	Minimum Tree Canopy Cover	Minimum Deep Soil Area	Minimum Tree Planting Requirement
< 300 m²	15%	15%	At least one small tree per lot
300 m² - 600 m²	20%	20%	At least one small tree per 200 m²
> 600 m²	25%	25%	At least one medium tree per 225 m²

Note: Existing trees on the site can contribute to these canopy cover percentage calculations, so preserving established nature is highly encouraged.  

2. Cultivating Biodiverse Green Cover

To build a resilient garden that can withstand pests, diseases, and weather extremes, planting diversity is non-negotiable. The landscape guide outlines several actionable rules for achieving a thriving ecosystem:  

• Allow for a minimum of 15 different plant species within the garden.  

• Include at least 3 different plant species from each core plant type: shrubs, grasses, and ground covers.  

• Aim to plant at least 50% native trees, which provide vital food, shelter, and habitat for local wildlife while requiring fewer resources.  

• Utilize dense planting strategies, such as aiming for 10 plants per square meter in garden beds featuring mass planting.  

3. Designing Purposeful Outdoor Spaces

At SN Architects, we focus heavily on how residents interact with their environment. The guide sets out specific parameters to ensure outdoor spaces remain functional, private, and environmentally sound:

Backyards and Courtyards

• Paved or decked areas should be limited to a maximum of 40% in backyards.  

• Turf should be limited to backyards and capped at a maximum of 30% to 35% of the area, depending on whether it is a manor home, row home, terrace, or semi.  

• Planting should cover a minimum of 35% of the total backyard area across all low-rise housing types.  

• Boundary fences should not exceed 1.8 meters in height, or 1.2 meters if constructed from masonry.  

Front Yards

• Front fences should be designed to be at least 20% transparent once they exceed 400 mm in height, maintaining street appeal and community connection.  

• Driveways should not be wider than their associated carport or garage.  

• Footpaths must be a minimum of 1.2 meters wide with a cross-fall of less than 1:40.  

4. Sustainable Materials and "Dark Sky" Lighting

Material selection plays a massive role in mitigating urban heat and managing stormwater.  

• 
  

  Permeable Paving: Permeable surface treatments—such as gravel, pebbles, or specialized pavers with voids—are highly recommended as alternatives to hard, non-permeable surfaces. These materials reduce stormwater runoff, allow rainwater to recharge groundwater, and can help passively cool the garden.  

• 
  

  Locally Sourced Materials: Designing with regional materials, such as Sydney sandstone, enhances connection to place while reducing environmental impacts from transport.  

• 
  

  Dark Sky Principles: To protect wildlife and reduce energy waste, the guide promotes "Dark Sky" lighting principles. This includes avoiding tree uplighting to protect foraging and roosting wildlife, using shielded fixtures to direct light downwards, and utilizing timers and motion sensors.  

Building the Future with SN Architects

The NSW Housing Pattern Book Landscape Design Guide provides a clear roadmap for creating housing that respects the local climate—offering specific plant palettes for varying NSW regions from warm humid summers to cool temperate zones .  

At SN Architects, we are fully committed to integrating these principles into our low- and mid-rise projects. By prioritizing deep soil, maximizing green cover, and implementing water-sensitive urban design, we can deliver homes that are not just beautiful, but vital to the health of our local ecosystems.
