“Thankyou most sincerely for a magnificent job. I’m thoroughly pleased with the “Taj Mahal” deck and pergola and it has already been put to good use. On Friday night it endured one of the heaviest storms we’ve had in years – and of course came through with flying colours. Thank you to you and your boys again!”

“GW Building was selected from a group of three tenderers to complete construction and landscaping works at our pool amenities site because of their professional approach during the tender process and their competitive price. The job was started on the agreed date and was completed by the estimated finish date which was important to us given the number of people who use the site. GW Building supplied all necessary documents prior to commencement of the work and complied with all our OH&S policies and requirements. The Site Supervisor was always onsite whenever spot checks were completed and the project was managed very well with no complaints received from residents. We would have no hesitation in using GW Building’s services again in the future and would recommend their services to anyone for any small or large construction or repair jobs.”
