Great communication, delivers on promises and good quality work.

We have worked with Merv from the Extension Company during two separate major extensions and alterations on period properties over the past ~5 years. Merv has always been excellent in communication and delivers on his promises, for example he has always arrived to start the jobs on the start date as promised, during the jobs he's always keep us informed on progress and kept the sites clean and tidy. Merv has a proactive can-do attitude and will work with you to deliver your vision or provide advice and knowledge to achieve great results. Quality of work is very good and we would certainly work with Merv again in the future. David and Lisa Rapkins

Excellent, reliable and conscientious Builder

The Extension Company have a carried out a number of building projects at my property including complete refurbishment of main house and garage conversion. Merv and his team were reliable, always turned up when they said they would and showed strong commitment to the job. Building standards were high and any recommended sub contractors proved equally reliable and competent. I have no hesitation in recommending the Extension Company.
