Bundaberg Region builder Nathan Groszmann Constructions won two categories at the Master Builders Queensland Housing and Construction Awards.
They received accolades on Friday night for Individual House from $550,000 to $650,000 and Excellence in Sustainability.
Owners Nathan and Peta Groszmann attended the ceremony in Brisbane and were delighted with the success.
“To say we are beyond proud, excited, cannot believe it, lost for words is an understatement,” they said on Facebook.
“We could of not gotten here without having an opportunity to do a build like this.
“Thank you to the clients for giving us this opportunity, all your research has certainly paid off!
“To all our boys and tradies we wouldn’t be here without you all; we are extremely grateful to have such an amazing team.”
The winning home is an eco-friendly building with a 9.1-star energy efficiency rating under the BERS verification method.
“This outstanding result was achieved through planning and implementation of solar passive design principles best used for the Wide Bay climate,” Nathan Groszmann said.
“The house concept, calculations and design were created by the home owner, a novice enthusiast in solar passive design, and digitised by a professional draftsperson.
“It's not out of reach for the general person, and an architect specialised in sustainability need not be engaged to achieve your dream home in terms of thermal comfort and sustainability.”
Peta Groszmann said the business has been operating for 10 years and this was the first time they had submitted an award entry.
She said the 9.1 star energy rating is a significant environmental benefit.
“It means they are fully self-sufficient, off the grid,” Peta said.
“There is no need for air-conditioning because cross-ventilation is used for cooling.”
John Gatley from Bundaberg was the building designer for the Nathan Groszmann Constructions winning entry.
Master Builders chief executive Grant Galvin applauded all winners across the 58 categories.
“This year’s awards celebrate the best of the best, featuring quality craftsmanship and innovative solutions to overcome obstacles during the building projects,” Mr Galvin said.
“This year’s winners have shaped our Queensland towns and communities. They are a true recognition of what our industry can do.
“The high calibre of entries shows our members are continuing to push the boundaries, provide sustainable solutions and produce quality projects.”
