Do You Need an Architect or a Building Designer?

When planning a new home or renovation, one of the first questions is whether to hire an architect or a building designer. Both can create building plans, but the differences go beyond titles. Understanding these differences ensures your project meets your needs, budget, and long-term vision.

Architects undergo formal university education, complete rigorous training, and must be registered to practice. This registration ensures compliance with legal, safety, and building standards, as well as design expertise. Building designers may have formal or practical training and can produce plans, but their scope of practice is generally more limited, especially for complex or high-value projects.

While both architects and building designers can produce construction drawings, architects focus on design thinking, spatial flow, and the overall experience of a home. Building designers often emphasize the technical documentation and compliance aspects, but may not always provide the same level of conceptual innovation or detailed design integration.

For simple residential projects, both architects and building designers can be appropriate. However, for larger, bespoke, or high-end developments — including luxury homes, multi-level extensions, or buildings with unique site challenges — architects bring broader expertise in planning, engineering coordination, and longevity of design.

Hiring an architect does not automatically mean higher costs. While design fees may be higher, architects often help clients avoid costly mistakes during construction by anticipating challenges early, coordinating with engineers and builders, and ensuring designs are buildable. A building designer may seem more affordable upfront but can result in adjustments or compromises later.

At ISA™, we combine creative, human-focused design with rigorous buildability. Our projects prioritise natural light design, material selection, and spatial flow while ensuring compliance, coordination, and longevity. This holistic approach ensures your home is not only beautiful but functional, safe, and future-ready.

Not always. Simple renovations or extensions may be suitable for a building designer, but complex, bespoke, or high-value projects benefit from an architect’s expertise.

Architects may charge higher fees initially, but their guidance often prevents costly construction errors and ensures long-term value.

Yes, building designers can usually manage approvals for standard residential projects, but architects are better equipped for complex regulatory or council requirements.

Consider the complexity, value, and uniqueness of your project, as well as the level of design creativity and coordination you require.

ISA™ is a registered architecture firm, focusing on delivering design-led, buildable solutions. We coordinate with other professionals when necessary, ensuring a seamless experience for clients.

Choosing between an architect and a building designer depends on your project’s needs, complexity, and long-term goals. Our registered architects provide a balance of creativity, functionality, and buildability, helping clients achieve homes that are both beautiful and enduring.
