Paul is a member of the Registered Master Builders Association and a Licensed Building Practitioner so you can rest assured he has the knowledge and expertise to ensure your renovation is a success. 

Our Services 

Our expertise ranges from highly complex architectural projects, to studio and garage conversions, bathroom and kitchen renovations, home or room additions, decks and patios, as well as detailed shop fitouts and light commercial work.

These services are provided all over Mid Canterbury and being locals, we are aware of the council requirements, weather conditions and the surrounding environment to perfectly design and build your next renovation or extension. We use the most up to date, modern building materials and methods alongside exceptional customer service to deliver you a renovation that completely exceeds your expectations. 

Our Process 

Being able to project manage renovations and extensions from the initial consultation and drafting of designs, right through to the final stages of construction, allows us to provide our valued customers with an easy solution for all their building requirements. Rather than separately employing the services of an architect, engineer and building company, we manage the entire process, including gaining appropriate building consents, from start to finish for you.
From concept to completion, Smith and Sons Ashburton provide the personal commitment, supervision and management to your project to ensure customer satisfaction and quality work.

What People Are Saying

It gives us great pleasure to provide the following testimonial from our recent renovation.

Sometimes DIY isn`t in your DNA, or like us too busy to commit the time to such a project.  It was such a wise move to obtain the services of Smith & Sons Ashburton to undertake our recent kitchen, dining and laundry renovation.

We were all done in three weeks with no delays, stress, dramas or conflict.  Our project manager Wayne sussed out our style, likes and dislikes very quickly and we were very much on the same page.  He assisted us to implement our ideas and we appreciated being able to utilise his industry experience to transform our ideas into reality.

Having a young family we acknowledge it isn`t always ideal to be living in the housing during a renovation and we appreciated the respect and professionalism the staff and sub-contractors showed to us.

A huge thank you to the Smith & Sons team, we are so pleased with the workmanship and the end result.  We are enjoying receiving many comments on our modern and functional living space.

- Andrew & Debbie Skinner

Smith and Sons transformed our small pokey home into a wonderful, spacious, open plan living space.  We are incredibly impressed by the workmanship that they offered.  We were also impressed with how tidy they kept the area at the end of the working day considering the extend of the remodelling; it was lovely to come home to a resonably clean house each day, while still being able to see the progress that had been made.

We have nothing but praise for Smith & Sons, they were professional, neat and tidy, and their attention to detail has given us the living space we desired.  We would recommend them to anyone and everyone.

We can’t thank Paul, Anna and the boys at Smith & Sons enough for making this whole move possible for us. Paul and the boys were with us every step of the way making our dreams and visions become a reality. A simple fitout in the newly constructed part of the original structure merged into something completely different in practice. We realised that there were things that worked on paper but as soon as we physically saw things we learnt that they would not work for the business in the long run. Smith & Sons Ashburton was right behind us all the way and made sure that everything we needed changed was done so to a very high standard. The input that Paul and the team gave us and suggestions for improvement in making the changes needed was invaluable and we would not have this brilliant structure to work out of today if it was not for them and their commitment to the build. It is a wonderful place to work from and we are extremely proud to have such great creators construct it and bring our vision to reality.
