What is a building designer? A look at what they do and when to hire one

Building designers offer a valuable service by delivering cost-effective and efficient design solutions for various building projects. Their expertise shines particularly in managing mid-tier builds with moderate complexity, where they ensure a smooth and streamlined design process. By prioritising both practicality and aesthetic appeal, building designers craft solutions that meet the client's needs while adhering to budget constraints. This approach allows them to maintain tight turnaround times and deliver high-quality results without compromising design or functionality.

Building designers typically hold a diploma or degree in building design, architecture, or a related field, often complemented by specialised certifications in areas such as sustainable design. They should also have accreditations from professional bodies like the Building Designers Association (BDA) in Australia and hold the necessary local licences. Their training includes proficiency in software programmes like AutoCAD or Revit, alongside a thorough understanding of building codes and regulations.

A building designer's work involves creating functional and aesthetically pleasing designs while ensuring building codes and regulations compliance. From initial concepts to final approvals, building designers balance creativity with technical expertise to deliver effective, well-designed spaces.

Services offered

Building designers provide a myriad of services that vary based on the project:

• Conceptual design: Crafting designs based on client vision and budget.
• Detailed design and drafting: Creating plans and coordinating systems.
• Regulatory compliance: Ensuring designs follow codes and securing permits.
• Client communication: Presenting options and maintaining feedback.
• Project coordination: Overseeing contractors and site inspections.
• Cost management: Estimating costs and adjusting designs for budget.
• Sustainable design: Suggesting eco-friendly, cost-saving solutions.
• Problem-solving: Adapting designs to challenges and changes.

Types of industries and projects

Building designers also work in a variety of industries and projects:

• Residential: Small homes, multi-family developments, apartments.
• Commercial: Offices, retail spaces, restaurants, hotels.
• Industrial: Warehouses, factories, manufacturing facilities.
• Educational: Schools, universities, training centres.
• Healthcare: Clinics, hospitals, medical offices.
• Hospitality: Hotels, resorts, event spaces.
• Cultural: Museums, galleries, theatres.
• Government: Public buildings, community centres, civic projects.

Building designers come from diverse backgrounds, with some specialising in residential homes and others focusing on commercial spaces like restaurants. If a designer lacks expertise in a specific project type, they may refer you to a specialist better suited to your needs.

Hiring a building designer is beneficial for a range of projects, particularly residential developments and smaller commercial or industrial designs. They can create customised plans for new homes, manage renovations and extensions to integrate seamlessly with existing structures and offer functional solutions for interior remodelling. For boutique offices or retail spaces, building designers provide tailored, cost-effective solutions that meet specific business needs. Engaging a building designer is often a wise investment as their expertise can ensure a professional, compliant, and efficient design.

Benefits of hiring a building designer

Hiring a building designer offers several benefits, especially for residential and smaller commercial projects. Building designers offer cost-effective, personalised design solutions, focusing on practical, functional spaces, regulatory compliance, and sustainable practices while collaborating with builders for smooth execution—making them ideal for projects with budget or time constraints.

1. Cost-effective solutions: Lower fees than architects; provides affordable design services, roughly 6% of the build cost.
2. Personalised, practical designs: Customised designs that balance aesthetics and functionality; tailored to fit your specific needs.
3. Compliance with building codes: Ensures your project meets all local regulations; knowledgeable about legal requirements.
4. Sustainable and energy-efficient options: Incorporates eco-friendly features to reduce costs and environmental impact; focuses on energy-saving solutions.
5. Flexibility for residential and commercial projects: Works on various projects, from homes to small businesses; offers versatile design solutions.
6. Collaboration with other professionals: Coordinates with contractors and builders for smooth execution; ensures the design is implemented effectively.
7. Faster turnaround times: Delivers designs quickly; ideal for projects with tight deadlines.
8. Creative problem-solving: Provides innovative solutions for design challenges; excels at overcoming site constraints and budget limitations.

Hiring a building designer may not always be the best choice, especially for more complex projects. An architect is often better suited for large-scale commercial developments, public infrastructure, or buildings requiring intricate structural or engineering. In regions like New South Wales, local regulations often require an architect for larger residential projects such as multi-unit buildings; architects are typically mandated for builds that exceed certain size or complexity thresholds.

• Building designers may not suit complex projects.
• Architects are best for commercial and public projects.
• NSW may require architects for larger residential builds.
• Architects needed for specific size/complexity projects.

When working with a building designer, the process is similar to that of an architect but with some key differences. Building designers typically focus on smaller-scale residential and commercial projects, while architects often handle larger, more complex designs. Although both professions involve creating functional and aesthetically pleasing spaces, architects tend to tackle more technical and structural challenges, especially for high-rise buildings or specialised spaces like hospitals. On the other hand, building designers offer a cost-effective alternative, specialising in designs that meet client needs without requiring intricate structural or engineering considerations. 

• Building designers: Best suited for straightforward projects like residential homes or small offices, focusing on practical design solutions without extensive structural or engineering complexities.
• Architects: Ideal for large-scale, complex projects such as high-rise buildings, specialised facilities (e.g., hospitals), innovative, high-end/architectural residential homes, and custom designs requiring advanced structural solutions.

When planning a building or renovation project, understanding the costs associated with hiring a building designer is crucial. Building designers play a key role in translating your vision into practical plans, often bridging the gap between drafters and architects. Their fees can vary based on several factors, including the project's complexity, their level of experience, and the specific services they offer.

Building designers typically charge in one of three ways:

1. Hourly rates: Expect to pay between $90 and $180 per hour. This rate can vary depending on the designer's expertise and the project's requirements.
2. Fixed fees: Some building designers offer a predetermined fee for the entire project. This can be advantageous for budgeting, providing a clear cost from the outset.
3. Percentage of building cost: The typical rate for a building designer in Australia is around 5% to 7% of the total building budget. This percentage reflects the designer's involvement in developing and refining the project plans
4. Per square metre: Some building designers may charge a rate based on the project size, typically ranging from $15 to $25 or more per square metre.

Choosing the right building designer is key to a successful project, and using a checklist ensures you cover all the important factors for an informed decision.

• Define your project needs: Clearly outline your project's scope, objectives, and budget; this will help you find a designer who meets your requirements.
• Research potential designers: Look for designers with relevant qualifications and experience in similar projects; ensure they match your needs well.
