Alterations & Renovations

Transforming Your Home With Smart, Cost-Effective Design

Renovating your home is an opportunity to enhance comfort, improve functionality, and refresh your living environment. At CBA Design, we specialise in creating renovation and alteration plans that integrate seamlessly with the existing structure—delivering practical improvements, modern design, and excellent long-term value. Since 2003, our Auckland-based design team has helped homeowners reimagine their spaces with thoughtful upgrades large and small. Whether you’re planning a kitchen remodel, a deck extension, a major reconfiguration, or a complete home transformation, we take the time to understand your needs and create clear, build-ready plans that suit your vision and your budget.

Comprehensive Alteration & Renovation Design Services

Every home has its own character, challenges, and opportunities. Our role is to identify what’s possible, translate your ideas into effective design solutions, and provide plans that builders can execute with confidence. We work with all styles of homes—from classic bungalows and villas to modern builds and multi-level dwellings. No matter the age or layout of your home, we offer renovation designs that feel natural, seamless, and carefully aligned with your lifestyle.

Kitchen & Bathroom Renovations

Kitchens and bathrooms are among the most important spaces in any home. We design functional, modern layouts that improve flow, maximise storage, and bring long-term durability. Whether you want a complete redesign or minor upgrades, we create plans that blend practicality with style and comply with all relevant building standards.

Outdoor & Decking Improvements

Outdoor living is a hallmark of the Kiwi lifestyle. Our team designs decks, patios, pergolas, and outdoor entertainment spaces that extend your living area and make better use of your site. From simple deck extensions to integrated indoor–outdoor flow enhancements, we ensure your improvements connect naturally with the existing home.

Home Extensions

When you need more space, extensions offer a cost-effective way to expand without the need to relocate. We design rear, side, and upper-level additions that look and feel like a natural part of your home, maintaining architectural coherence while improving functionality. Our extension plans can include new bedrooms, living areas, bathrooms, home offices, and more.

A Tailored, Collaborative Design Process

At CBA Design, renovation design starts with listening. We take the time to understand how you use your home today and how you want it to work in the future. From there, we explore options, feasibility, and budget considerations to create designs that deliver meaningful improvements. Our renovation design process includes:

Designs That Respect Your Home’s Original Character

When altering an established home, it’s important to protect its charm and structural integrity. Our team understands how to blend modern upgrades with existing architectural styles—whether you own a villa, bungalow, 1960s home, or contemporary property. We carefully consider rooflines, materials, styles, and proportions to ensure the final result feels cohesive and enhances your property’s long-term appeal.
