If you dream of designing homes and other small buildings but don't want to spend the years it takes to become a registered architect, then you may want to explore career oportunities in the field of Building Design. The path to becoming a Certified Professional Building Designer® or CPBD® is achievable and rewarding for many people. As a Building Designer, you could be invaluable in assisting people not familiar with the construction and home remodeling business. Although you are not legally required to pass the same registration exams demanded of architects, you'll want to become certified in your own field. Even if your state doesn't require certification, you'll be more marketable with professional certification, just like medical doctors become "board certified" after medical school.

Building Design is different from what is known as Design-Build. Although they are both types of processes, Design-Build is a team approach to building and design, where the building contractor and building designer work under the same contract. The Design-Build Institute of America (DBIA) promotes and certifies this type of project management and delivery system. Building Design is an occupation — a field of study taken up by a person who becomes a building designer. The American Institute of Building Design (AIBD) administers the certification process of building designers.

What is a Home Designer or Building Designer?

A Building Designer, also known as a Professional Home Designer or Residential Design Professional, specializes in designing light-frame buildings such as single- or multi-family homes.  In some cases, as state regulations permit, they may also design other light-frame commercial buildings, agricultural buildings, or even decorative facades for larger buildings. Having a general knowledge of all aspects of the building trade, a Professional Building Designer can act as an agent to help the homeowner through the building or renovation process. A Building Designer can also be part of a Design-Build team.

Each state determines licensing and certification requirements needed to practice architecture. Unlike architects, Home Designers are not required to pass the Architect Registration Examination® (ARE® administered by the National Council of Architectural Registration Boards) to receive a professional license. Completing ARE is one of the four steps to a life in architecture. Instead, a designer who carries the title Certified Professional Building Designer has completed training courses, practiced building design for at least six years, built a portfolio, and passed a rigorous series of certification exams. Receiving National Council of Building Designer Certification (NCBDC) commits this type of building professional to standards of conduct, ethics, and continued learning.

Certification Process

The first step to becoming a Professional Building Designer is to set your goal for certification. What do you need to do to apply to become certified?

  • Fill out an application and pay the nonrefundable application fee
  • Have three letters of verification from professionals in the field of building and design
  • Have six years of experience, a combination of education (documented course work) and supervised on-the-job training (your supervisor will have to fill out a form)

Learn some of the craft of building design before you even apply to become certified. So, to begin your quest, start with the six years of experience requirement.

Training Before Certification

Enroll in training courses in architecture or structural engineering. You may take classes at an accredited school of architecture or at a vocational school — or even online, if the school is accredited. Look for courses and training that will give you a broad background in construction, problem solving, and architectural design. Instead of academic training, you may study architecture or structural engineering on the job, under the supervision of a building designer, architect, or structural engineer. Throughout architectural history, apprenticeship has been the way building designers and architects have learned their craft.

On-the-Job Training

On-the-job training is essential to receive certification as a Professional Building Designer. Use the career resources center at your school and/or online job listings to locate an internship or entry level position where you can work with architects, structural engineers, or building designers. Begin building a portfolio with working drawings for design projects. Once you have accumulated several years of training through coursework and on-the-job training, you will be eligible to take the certification exams.

Certification Exams

If you wish to find a job and build a career in building design, consider working toward obtaining certification in the field. In the U.S. professional Building Designers are certified by the NCBDC through the AIBD. You can download their CPBD Cadidate Handbook to learn about the process and apply to take the online exam. After you have submitted your application, you move through the process as an Applicant to a Candidate and finally to become Certified.

When you apply for certification, you will be asked for letters from professionals who can verify your experience. Once these are approved, you have 36 months (3 years) to pass all parts of the open book, online exam. You don't have to be perfect — in the past 70% has been a passing grade — but you have to know a little about subject areas that are not directly related to building, like some architectural history and business administration. The exam questions will cover many phases of construction, design, and problem solving. You will be permitted to refer to several approved reference books as you take the exam, but just like problem solving on the job, you won't have time to search for answers — you have to know where to look.

A word of caution: Before you give any money to AIBD, make sure you understand what is required of you before you begin taking the exams. Testing organizations are always updating their questions and processes, so go into this endeavor with eyes wide open and with up-to-date information. Although the current examination process is online, it cannot be taken anytime you want — the candidate must pay for and schedule each test, which is timed and monitored by a real person via the camera and microphone on your computer.

Like other certification-type examinations, the CPBD exams include questions that are multiple choice multiple answers (MCMA) or multiple choice single answers (MCSA). Past exams have included True and False, Short Answer, and even sketching designs and problem solving. Areas of examination may include:

  • Business Administration and Practices: Questions may include describing contract terms, showing your knowledge of mechanics liens and due diligence, the ethics of online publishing, and hiring practices basics, such as knowing the difference between employees and independent contractors.
  • Design Process:  Questions about concept and construction development may include your knowledge of symmetry and proportion, about residential architectural styles in the U.S. or how Renaissance architectur  continues to influence today's building designs.
  • Building Design: Most of the certification examination questions will concern the nuts and bolts of designing a building, including Building and Fire Codes; types of roofs, foundations, and wall systems; the nature and use of materials like concrete, masonry, and wood; calculating footing sizes or joist sizes in different scenarios; using beam deflection formulas; energy efficiency and sustainability; thermal and moister protection; and Mechanical, Electrical, Plumbing (MEP).

    If all this seems over your head, do not be discouraged. The NCBDC offers guidance that will help you prepare and keep your career going. You will also find the material you need to know in this reading list, many of the classic textbooks used by professionals.

    Continuing Education (CE)

    Architects don't have a market hold on construction in most parts of the United States. In Europe there may be no alternative — architects there have warned us about "unqualified charlatans." In the U.S., however, there are alternative routes to residential home design.

    All professionals, whether architects or building designers, are committed to continuing their education after gaining licensure or certification. Professionals are lifelong learners, and your professional organization, AIBD, will help you find courses, workshops, seminars, and other training programs.
