“It’s a matter of sitting down with you and figuring out what you want; your styles and your preferences and how you want to work or live in the space… and then putting that on paper.”
William Arends, Founder and Principal Designer
Your ideas drive every stage at Fundamental Design Studio. You receive bespoke architectural design for homes and businesses across Wellington, Hutt Valley, Kāpiti, Wairarāpa and beyond, all shaped by your needs and preferences.
Whether you’re planning a new build, renovation or commercial project, your journey is personalised from concept right through to council consent.
Clear communication and ongoing support make the architectural process smooth, creative and enjoyable. The result is a space that’s both beautiful and practical, ideally suited to your lifestyle or business.
Building industry experience and expertise you can trust
William began his career as a builder’s labourer while completing a Bachelor of Building Science at Victoria University. He later moved into building compliance consultancy and spent time as a Building Officer at Hutt City Council — so your project benefits from expertise in both architectural design and the NZ Building Code.
That experience means potential compliance issues are spotted and resolved before they become expensive problems.


Personalised architectural design service from start to finish
“I want to provide a service where you feel you can make changes when you need to. If problems come up they can be solved together instead of you having to figure it out by yourself.”
As a solo practice based in Upper Hutt, Fundamental Design Studio serves the wider Wellington region. You get a personalised, client-focused alternative to larger firms — flexible consultation times, evenings and weekends included.
