Waste is a design flaw, the ability to create circularity of all materials eliminates waste and builds a sustainable world.”
– Kate Krebs
A Restorative and Regenerative Approach to Design
At Arkular, we adopt circularity throughout each phase of a dwelling’s life cycle. This is assists in optimising resources, reducing material usage and minimising waste.
The main aim of our circular approach is to:
– Reduce embodied carbon
– Minimise the generation of waste
– Improve materials efficiency
– Increase the circularity of materials
We are designing homes for longevity and consider each phase of a dwelling’s life cycle, from concept to completion and beyond.
What is Circular Design and Why is it Important?
A circular model of production and consumption addresses serious challenges being faced including climate change, waste, pollution and biodiversity loss.
In a circular economy, products are either recycled, re-manufactured or re-used after they have served their initial purpose.
Currently, most of the world operates in a linear economy that involves taking, making and wasting. Integrating principles of circularity into the built environment will enable repair, reuse and recycling and ensure protection from the rising economic, social and environmental implications of waste and pollution.
The Need for a Circular Approach in the Construction Industry
The ABS indicated the construction industry was the second biggest producer of waste over the 2018-19 financial year, generating roughly 12.7 million tonnes (16.8%) an increase of 22% since 2016-2017.
“The construction and demolition of buildings account for around one-third of global material consumption and waste.”
– Ellen MacArthur Foundation
A 2021 study conducted by the University of New South Wales found a significant reduction in waste through modular construction in comparison to conventional on-site methods, with an 83.2% reduction in the weight of waste.
Arkular’s modular method of manufacturing has a significant environmental edge over traditional on-site construction with reduced site disruption and material wastage, being highly resource efficient, cost-effective and streamlined.
Arkular’s Application of Circular Design
At Arkular, we are thinking ahead about what we leave behind. We are mindful of our environmental impact throughout each phase of a home’s life cycle – from concept to completion and beyond.
Our homes are designed for:
• Recyclability
• Resource efficiency
• Energy efficiency in use
• Longevity / durability
• Repair, reuse and disassembly
Longevity begins with a quality design that encompasses the needs of the occupants, site and landscape. We then consider the resources and materials we use, our manufacturing process, the use of the home and the recyclability of our dwellings to create customised, sustainably driven homes that are built for the long run.
Resource Efficiency
Harnessing and optimising resource value, we prioritise high-quality, sustainable and environmentally friendly materials.
The resources and materials we use can have a large impact on the environment and our health and well-being, so we prioritise using Australian-made, locally sourced, sustainable and eco-friendly materials.
To minimise environmental impact, we recommend using low-VOC timber, paints, adhesives, sealants, formaldehyde-free products and sustainably sourced timber, stone and leather. We also recommend using products within your home made from plant-based materials to help lower greenhouse emissions and minimise contact with harmful chemicals, all contributing to a healthy home, family and life.
Just some of the sustainably-driven, Australian-made brands we opt for include:
Colorbond, Weathertex, Dulux, MadeMeasure, Laminex, Plank Flooring and Kōbe Cement Bonded Wood Composite.
Manufacturing
The prefabricated modular nature of our homes allows for the building to be constructed in a manufacturing facility, before being transported and assembled on-site. Benefits of opting for a prefab home include:
– Less waste production due to more controlled construction environments
– Reduced emissions and pollution due to off-site construction and shorter timeframes
– Reduced disruption to the site, surrounding landscape and local flora and fauna
– Cost savings through faster construction times, streamlined processes and less labour

Use
Durable and adaptable, we design our homes to meet your requirements, the site’s location, the surrounding landscape and weather patterns.
This is done by utilising:
– Passive solar design principles
– High-quality materials, fixtures and fittings
– Water conservation techniques
– Energy-efficient appliances
We are designing for the long run and consider the current and future needs of the space to ensure your home can shift and change and that it is in use for as long as required. Effective architectural design adapts to evolving requirements, providing a home that is useful throughout its lifespan. People’s lives and situations constantly change, reflecting how design needs flexibility and modularity.
Reuse, Repurpose and Recycle
At the end of the building’s life cycle, Arkulars dwellings can be uninstalled, disassembled and relocated if required. Disassembly allows for the reuse, repurposing or recycling of building components.
Materials we utilise that can be recycled or repurposed, include:
Colorbond – All Colorbond steel contains recycled content and the steel itself in Colorbond steel is 100% recyclable. In some cases, it can be reused without reprocessing.
Timber – Untreated timber can be easily reused or recycled for future use.
Plaster – Plaster can be used to plug holes, make wet concrete supports and treat newly laid garden beds. It can also be recycled, becoming paperboard or plasterboard.
Glass – Glass is one of the most available materials that can be reused and recycled within construction.
Fish Creek House – Sustainably Driven, Environmentally Focused
Mindfully designed for energy efficiency and minimal environmental impact, The Fish Creek House was inspired by permaculture and nature, with the occupants seeking to be autonomous and minimise their carbon footprint.
Resources
Sustainability is at the core of the home, extending to the internal furnishings and décor, with nearly everything being repurposed or sourced second-hand. Carbon-neutral materials were selected throughout providing health benefits to residents and having a light impact on the environment.
We prioritised locally sourced, sustainable materials including Low VOC paint from Dulux, Colorbond cladding with sustainable timber and a solar power system, rainwater tank and CFA water tank 10,000L for firefighting requirements.
Manufacturing
The prefabricated modular method of manufacturing The Fish Creek House offered a significant environmental advantage over more traditional construction methods, with reduced disruption to the site and surrounding landscape, minimised material wastage, effective utilisation of resources and streamlined processes.
Use
The living, kitchen and dining spaces are oriented towards the north to provide natural light and heat from the sun, whilst the sleep module is oriented towards the northwest, cross ventilation has been achieved via strategically placed operable windows/doors, and natural light is provided to all habitable rooms via operable glazing and a pergola with timber battens is included to provide protection from the sun.
Clever design and mindful additions have created a home for longevity, that will be enjoyed now and in the future.
Reuse, Repurpose, Recycling
Due to the modular prefab nature of the home, at the end of the building’s life cycle, it can be easily transported or disassembled allowing for reuse, repurpose or recycling of building components.
