Creating architectural residential new home builds, designed around you

Building a new home is one of the biggest creative and financial decisions you'll make. At CA Arch, we design homes that respond to your lifestyle, your site and your future, while providing clarity around design, cost and the path ahead.

From Christchurch to projects throughout New Zealand, we help homeowners, developers and families turn ideas into considered architectural spaces.

Start Your New Home Conversation

Great homes start by listening

At CA ARCH, every project starts with listening, really listening.

Clients often tell us this is Casey's strength: understanding what people actually need, asking the right questions and refining ideas until the design genuinely fits.

A successful home isn't just about how it looks. It needs to work with your lifestyle, your site, your budget and the way you want to live.

That means understanding the bigger picture early, including site constraints, construction realities, lending requirements and the decisions that will shape your project long before construction begins.

Why Choose CA Arch?

Design confidence before committing

Our concept design process helps you explore ideas, refine your brief and understand how your vision aligns with your budget before committing to the full design journey.

A stronger foundation before design begins

With TK's background as a qualified mortgage adviser, CA ARCH brings a unique understanding of the relationship between design decisions, project feasibility and funding requirements.

Where appropriate, we help connect clients with trusted partners including registered valuers, geotechnical engineers, structural engineers and quantity surveyors early in the process.

Support beyond the drawings

A successful build requires more than great design. We help coordinate the wider process, from early feasibility and consultant engagement through to consent and construction support.

Meet Casey

"The best homes come from understanding the people who'll live in them. My role is to listen first, challenge assumptions, and design spaces that genuinely improve everyday life.”

Every project is unique, but every successful project begins with understanding.

We combine creative thinking with practical planning, balancing design ambition, budget, council requirements and long-term performance from the very beginning.

Frequently asked questions about residential new builds

A registered architect or architectural designer can help turn your ideas, site and requirements into a considered, buildable home design.
Beyond creating drawings, an architect helps navigate important decisions around layout, materials, site conditions, budget, council requirements and building performance. Engaging an architectural designer early can help avoid costly changes later and create a home that works well for the way you live.
The cost of architectural services depends on the size, complexity and level of involvement required for your project.
At CA Arch, we focus on creating clarity early in the process. Our concept design package includes revisions and a complete pricing package, helping you understand whether your design aligns with your budget before progressing further.
Every project is different, so the best place to start is a conversation about your site, ideas and goals.
Every project timeline is different, depending on the complexity of the design, council requirements, decision-making and project scope.
As a guide, new residential builds typically take a minimum of around six months to reach building consent submission. More complex projects, resource consent requirements or larger homes may require additional time.
