    Our Story…

    BuildSmart was an idea hatched by Glen Williamson.  His experience and passion for investing in property, combined with a newly acquired building qualification were the perfect mix for a company.

    Glen had a wealth of knowledge to share with investors and home owners wishing to develop their properties.  Whether it be sub-dividing a site and building an additional dwelling, or simply adding on to existing homes.  BuildSmart quickly built up a strong reputation as the go-to building company for property investors and renovators in Dunedin.

    As the company grew Glen quickly realised communication was an integral part of the building process.  He very cleverly introduced the use of video technology, ensuring clients are kept fully informed throughout their building process. Any variations that may arise in renovations are videoed, and a link is sent to the client ensuring they are fully informed and part of the decision making process.

    BuildSmart continues adopt the latest technology as they grow. This adds another layer of communication with the clients, ensuring they are an integral part of the decision making process. The hassle and stress is reduced, while the project is managed from start to finish by a team you can trust.

    Growing up Shane could never sit still and loved helping his Dad with what needed to be done on the farm. He showed a natural ability for problem solving, construction and had an amazing work ethic from a very young age. It came as no surprise that he was running architectural new builds while still an apprentice.

    Now a qualified builder with over 15 years experience, he is very efficient and organised on and off the tools making him the perfect person to oversee the BuildSmart team.

    Shane has been with BuildSmart since 2014, previously owning his own company for 7 years where he specialised in residential new builds. Shane is a fantastic communicator with all trades and clients, ensuring that all jobs run smoothly and efficiently.

    Although now off the tools day-to-day he gets his ‘practical fix’ on his own properties. Outside of work, Shane enjoys spending time with his wife and two daughters and heads out hunting whenever he can.

      Glen Williamson

      Director/Project Manager

      Ileft school priding myself on having read only one novel throughout my teenage years.  I was a typical Kiwi teenage boy and my “educational” goal was to get sportsman of the year.  This I achieved, along with the necessary academic qualifications, however school for me was sport and socialising.

      Upon leaving school I studied as a Personal Trainer and went on to build a strong clientele in New Zealand and later the UK.  While continuing to work as a Personal Trainer, I developed and interest in investing.

      Suddenly I was motivated to read…  I read every property investment book I could get my hands on.  Upon returning to New Zealand, I implemented my new found knowledge under the guidance of an experienced mentor.

      From here my interest in building and renovating grew and I accepted an apprenticeship with a local Dunedin builder. I’ve built 20 plus new builds and a few hundred large and small renovations while working in the building industry.  When it comes to renovations I’ve got it covered.

      Whether it be sub-dividing a site and building an additional dwelling, upgrading existing homes, or simply adding on, I have a wealth of experience ensuring your renovation project is in safe hands.
