Energy-Efficient & GreenSmart Home Design in Southern Tasmania

Design your dream home the smarter way — comfortable, sustainable, and built for Tasmania’s climate.

Smarter Design. Lower Bills. Better Living.

At Willdesign, based in Hobart, we specialise in creating energy-efficient homes that are beautiful, functional, and future-focused. As an HIA GreenSmart-accredited designer, we integrate the latest in sustainable design principles to help you save on energy costs, reduce your environmental footprint, and enjoy a healthier home all year round.

Whether you’re planning a new home, renovation, or extension, our tailored approach ensures your home is designed to perform as well as it looks.

Whether you’re renovating in Sandy Bay, building new in Kingston, exploring modern layouts in Margate, or designing for the landscapes of the Huon Valley, our GreenSmart approach adapts to your local context.

Why Choose an Energy-Efficient Home Design?

Designing with energy efficiency in mind isn’t just about being environmentally conscious — it’s about building a home that works for you. With Tasmania’s unique climate, the right design can make a big difference.

The Benefits of Energy-Smart Design

  • Lower energy bills — reduce heating and cooling costs by up to 50%.

  • Smarter comfort — enjoy year-round temperature control without over-relying on systems.

  • Healthier living — better air quality and natural light create a healthier home environment.

  • Future value — sustainable, energy-efficient homes are increasingly sought-after by buyers.

GreenSmart-Certified Design Expertise

Not all designers are the same — and not all homes perform the same.
Our GreenSmart accreditation means we’re trained to design homes that achieve higher energy performance without compromising on style or functionality.

How We Do It:

  • Passive solar design — capturing natural warmth in winter and minimising heat in summer.

  • Smart orientation — maximising sunlight, airflow, and natural light.

  • Sustainable material choices — selecting products that are durable, efficient, and eco-friendly.

  • Insulation & glazing strategies — optimising thermal performance for Tasmania’s climate.

  • Renewable-ready design — future-proofing homes for solar panels and battery storage.

Featured Project: Off-Grid Rural Farmhouse, Waterhouse, TAS


Designed for a rural farmhouse property in Tasmania’s north-east, this home combines energy efficiency with fully self-sufficient living.

Featuring solar panels, battery storage, and gas-fed cooking and hot water with rainwater catchment, the design ensures complete independence from mains utilities.

Careful passive solar planning, durable low-maintenance materials, and integrated sustainability features deliver a home that performs beautifully year-round while reducing environmental impact.

While our roots and most of our work are grounded in Greater Hobart and Southern Tasmania, we bring the same commitment to remote projects like this one.
