Design & Construct


The beauty of a full in-house team lies in the symphony that comes from the orchestra. With Ben Spannenberg as your lead and coordinator, everything from site consultation through to design, council red tape, site and financial management, through to project management and handover are held in the palm of our hands.

An organised system humming to create a stunning result, which reduces build costs, simplifies the entire construction process and enables you to create an extension or renovation that delivers your dream outcomes within your budget.

No more architectural plans the banks won’t finance. No more last minute changes to adhere to council regulations. No more last minute compromises to make something go through. All backed by Ben’s personal guarantee.


Most people enter the journey of a home renovation or extension without any previous experience or knowledge about how the building process works or what, if anything, they have to take care of. At Spannenberg & Sons, we are here to take the entirety of the project out of your hands so you can enjoy the journey and concentrate on what’s most important, you and your family.

  • Lets meet - We will meet on site for a nominal fee to discuss your requirements and design options to meet your style and budget.
  • Design - If you don’t already have plans, we will provide a sketch design including front elevation and floor plan to fit your requirements.
  • Formal Quotation - We will provide a thorough and itemised written quotation, including your prime cost items and price options.
  • Proceeding - On acceptance of our quotation we organise the engineering details, energy efficiency assessments (BASIX), building specifications and working drawings and then submit it all to council for you.
  • Contract Signing - We meet up and sign a plain English fixed price contract supplied by the HIA.
  • Construction - You will be kept updated and informed through every stage, with your personal Project Manager or Ben Spannenberg available at all times.

  • Maintenance and Warranty - We provide a full six-year structural warranty and attend to any issues or any rectification works that require completion during the defects liability period of three months.
