Testimonials (3 testimonials)

Single storey extension to the rear and front of the property. Partial garage conversion to create utility room and cloakroom.


We have been delighted by the work done by Penco Builders Ltd to extend and improve our home. We admired the work they had done for a neighbour and followed their recommendation. The Project started with the concept and planning stage. Greg has a good eye for design and practicality. He listened to our ideas and suggested improvements to maximise the benefits to us. His design took account of our council's restrictions and was quickly approved by the council's officers. We agreed on a work programme, which was designed around us. The team arrived punctually and left the site in good order each day. Work which impacted directly on us was scheduled for days when we could be absent. Each phase of the project was delivered to time despite a lot of different weather conditions The quality of work was very high; weak lintels were identified and replaced, allowing modern windows, sympathetic to the house to be installed. The interior finishing (woodworking, flooring, painting) has been meticulous. Greg both worked with, and supervised his team closely. Greg invited our views at all times, offered us options on designs and constantly checked that we were satisfied. When the possibility of variation came up, Greg again was open to our thoughts, was open about estimates, and honoured his quotations. We look forward to working with Penco on other projects in our home soon.

Existing upstairs floor reconfiguration


I have heaps of praise for this fabulous company! The work these chaps have done on our cottage is second to none. A very professional team! The work carried out by these guys is excellent and to detail. Greg offers great advice on what you would need and preplans the jobs required to a timetable. A truly amazing team.



We hired Penco Builders to construct a two storey side extension for us. The work created an extra bedroom with ensuite and a number of internal alterations were also conducted and we are very happy with the result. We chose Penco for three reasons. Firstly they were recommended to us by a friend who had recently worked with them and we could see their build had been completed to a high standard. Secondly, when we first met with Greg he understood our requirements and we got the feeling we could work well together. Finally where other builders would only give ballpark quotes at an early stage, Greg produced a very accurate quote which enabled us to budget and was very helpful. Once work had started on the build progress was rapid and Greg’s friendly team worked hard to keep the build on schedule. Of course with any large project a couple of issues did arise but Greg met with us ASAP, often at short notice and solutions were found quickly. As we were living in the house during the build, Greg was mindful of this at all times and ensured minimal disruption for our family. We also added a few extra jobs during the build and Greg was happy to accommodate these. Any snags found post completion have also been rectified swiftly. The end result both inside and out is excellent. We’ve had many comments from both friends and neighbours at how well the extension matches the existing house due to the materials used and design, "it looks like it’s always been there" is a frequent comment.
