Tim Marshall

As Riverstone’s Co-Owner/Director, Tim heads up the construction, estimating, scheduling, drafting and accounts teams. As a student, Tim spent school holidays working on building sites alongside brickies and roof carpenters, and later gained his builder’s ticket through TAFE while working at Riverstone during the day. The company’s registered builder, Tim is well aware of the day-to-day demands of creating a new Riverstone home. It is his job to make sure clients know exactly how much their new home will cost, and then oversee installation.

Tim’s role as Operations Director enables him to explore many of the issues that affect the residential building market, from state-of-the-art new construction materials to the latest ‘green’ products. “I like keeping up to date with what’s happening out there in the market and maintaining the quality that we pride ourselves on.”

Alan Kranz

Alan Kranz has been with Riverstone since its inception and describes himself as “old-school” with a focus on quality, value and individual design.  “I do all my sketches by hand, not to a particular scale, but instead getting the room locations and proportions correct. I like to explore as many alternatives as I can for each particular part of the design, which often means taking it in different directions until I find the best solution.” This process can take hundreds of sketches until it all falls into place.

Alan started in the building industry in 1980 working as a draftsperson. After several years and a few different companies, he eventually moved into the design side of the industry, before being offered the position of building designer for a then exciting new company, Riverstone Construction. Alan has earned many industry design awards over the years, but says a client loving their individual design is the biggest reward of all.
