Custom Residential Building Design and Plan Drafting Services

Town house concept design - Paradise Point, Gold Coast

SKETCH3D designs custom new homes, premium house renovations, and seamless home extensions tailored to your lifestyle. Based on the Gold Coast, we service clients from northern New South Wales up to southern Brisbane and the Scenic Rim—and we are always willing to travel further for the right unique project.

Our premier design expertise is backed by over 30 years of local and international industry experience. Operating both locally as a QBCC licensed building designer and in the United Kingdom as a Chartered Architectural Technologist, SKETCH3D has been widely associated with both cutting-edge modern and sensitive historic projects.

Our work has been featured on UK television and in premier design publications, and we have proudly served as regular expert professional advisors to the public attending Grand Designs Live in the UK.

For an initial complimentary consultation, we will take the time to meet you in person, on site or at your home to talk through your needs and provide you with fresh home design ideas. A detailed quote is then prepared based on your requirements and budget. To book an appointment, please contact us.

We take the stress out of the entire building process by providing expert coordination for all necessary consultants and applications—including geotechnical reports, structural engineering, energy evaluations, and certifier applications. As a fully QBCC-licensed practice, we provide a professional, end-to-end service with highly competitive fees.
