CUSTOM RESIDENTIAL BUILDING DESIGN FOR REGIONAL, COASTAL, URBAN AND HERITAGE SETTINGS

Life doesn’t fit inside a floor plan — so we don’t design that way.

At Ark Group, we begin with how you live — your rhythms, your values, your vision — and we shape a home around it.

We’re a residential building design studio based in Castlemaine, led by Dennis O’Dwyer. With more than 25 years of experience, we’ve supported families, couples and individuals through renovations, new builds and complex planning projects — always with care, creativity and clarity at the core.

Our work spans regional towns, coastal environments, heritage overlays and infill blocks. Whether you’re seeking calm, flow, function or a deeper connection to your land, we approach every project as a collaboration — not just a service.

We’re building designers. And we believe great design should work hard and look good.

DESIGN EXPERIENCES

Designs shaped by setting, story and lifestyle.

Every project is unique — but we’ve noticed the best ones start with a clear intention. That’s why we frame our services around experiences rather than rigid offerings. We guide you through the full scope of building design services, tailored to your project type.

Start with clarity. Build a home that blends form, function and lifestyle.

OUR
PROCESS

A complete service. A practical, professional approach.

Designing a home isn’t just about drawing walls and windows. It’s about navigating the site, the vision, the council process, and builder handover — and knowing what to expect at each stage. That’s what we’re here for.

STAGE 1

Site Insight + Concept Design

We begin with the land — how it flows, where the light falls, and what the planning overlays mean for your vision.

  • Site visit and orientation analysis

  • Understanding slope, bushfire (BAL) rating, and views

  • Early floorplans, elevations and 3D renders

  • Passive design and solar consideration

  • Initial budget and compliance guidance

  • Pre-planning advice

STAGE 2

Planning & Approvals

We prepare everything needed to satisfy council, consultants, and anyone involved in approving your build.

  • Site overlays,design compliance, and town planning drawings and permit-ready documentation

  • Navigation of local overlays and zone-specific requirements

  • Coordination with engineers, surveyors and consultants

  • Ongoing liaison with council during the process

STAGE 3

Construction Documentation

We get your project ready for builder handover — including the detail needed to quote, build and complete the job.

  • Full construction drawings (NCC 2022 compliant)

  • Working drawings for quoting and builder selection

  • Referrals to trusted local builders and trades

  • Ongoing support throughout the build (if needed)
