Simon Penn Building is a locally owned and operated residential building company delivering high-quality, thoughtfully crafted homes across Whanganui and the wider district.

With a dedicated team of qualified foremen, carpenters and apprentices, we take pride in exceptional workmanship, meticulous attention to detail, strong project management, and clear, honest communication throughout every stage of the build.

Our commitment goes beyond simply constructing your home. From concept to completion, we manage your project with professionalism and transparency, keeping you informed and involved every step of the way. We take the time to understand your requirements and will custom build to suit your lifestyle, needs and long term vision. Backed by extensive construction knowledge and proven management expertise, we ensure every home is built to the highest standard and delivered with confidence.

You can choose from our range of well-considered home designs, adapt an existing plan or bring us your own ideas. We enjoy collaborating with our clients to create homes that reflect individuality, function beautifully, and stand the test of time.

For clients seeking the very highest levels of comfort, energy efficiency, and sustainability, Simon Penn Building also offers eHaus homes as a specialised building option.

We are the local eHaus Licensee for Whanganui and the wider Whanganui District. eHaus design and build beautiful, high-performing homes that set a new benchmark for comfortable and sustainable living. Designed specifically for your climate and lifestyle, every eHaus is built to rigorous global performance standards.

At the heart of every eHaus is a choice. How far do you want to go when it comes to comfort and performance? We offer three performance levels: eHaus Pacific, eHaus Euro, and Certified Passive House. All significantly exceed the minimum requirements of the New Zealand Building Code.

Every eHaus is architecturally designed, reduces carbon emissions, and delivers an average of 86 percent heat energy savings. Sustainability is embedded throughout the entire process, from design through to construction, with materials and systems carefully selected to reduce energy use, minimise waste, and lower environmental impact.

eHaus homes have been widely recognised for excellence, with more than 40 national awards for design and construction, making eHaus New Zealand’s most awarded high-performance home builder. Choosing an eHaus is about more than building a beautiful home. It is a conscious decision to invest in comfort, health, and a better future for generations to come.
