Architect led, Leanhaus collaborates with clients and select builders to deliver high quality with cost certainty
building science optimised design
Imagine living in a building that keeps you warm and cosy all winter, without running the heater. A home that’s quiet, free of draughts, mould and dust, costs very little to run and reduces your carbon footprint.
Leanhaus strikes the perfect balance between design, quality and cost. We deliver high performance Architecture for less by following lean construction and design principles.
“Ben took on a demanding brief and a challenging site, and produced a clever, practical design in an efficient and affordable manner, whilst satisfying complex planning criteria and delivering Passivhaus performance. The finished residence is a healthy, comfortable and wonderful place to call home.”
Passive House optimised, Leanhaus provide genuine solutions towards a net zero carbon future
energy efficient
Passive House is the leading standard on energy savings worldwide. Energy savings amount to 90% in comparison with current building standards. We achieve this enormous energy conservation through scientific design optimisation, special energy efficient building elements and ventilation techniques.
healthy
Air pollution indoors can be up to 5x worse than outdoors. Dust, mould, expired air, CO2 and contaminants from cooking all create an indoor environment that contributes to allergies, asthma and sleep disturbance. Leanhaus homes provide a constant supply of fresh, filtered and preconditioned air that is better quality than outdoor.
comfortable
Comfort in a Leanhaus is perceptibly improved by designing with consideration to air temperatures, surface temperatures, draughts and relative humidity. The home benefits from a relatively constant internal temperature that is well within the human comfort range. A constant supply of fresh air ensures CO2 concentration is within recommended limits.
92% carbon reduction against benchmarks.
Passive Design Optimisation
Passive House design optimised in house (Design PH and PHPP)
Highly efficient building envelope to minimise unwanted heat gains and losses.
Solar Passive Design and Passive Cooling design strategies to maximise comfort.
Airtight and thermal bridge free construction.
Limit upfront embodied carbon
We greatly reduce or eliminate the requirement for carbon intensive structural concrete and steel
Low carbon timber and renewable materials preferred.
Materials sourced locally where possible
Design to reduce waste through careful selection of products for module size optimisation
Consider whole of life carbon
Cradle to grave philosophy considers impacts at each stage of a product's life-cycle.
Preference for timeless style and quality materials to ensure long life that will not require premature disposal and renewal.
Preference for materials that require minimal on-going maintenance. We avoid applied external finishes that require constant renewal.
We prefer composite structures can be readily dismantled and re-used at end of life.
Our homes have been certified to show up to 92% carbon reduction against benchmarks.
