Alterations are some of the most demanding projects and are a measure of the skills of a building team. They are also incredibly rewarding, completely transforming spaces or creating new ones for families to enjoy for many more years to come. Onsite Builders thrive on such challenges as seen in some of our recent projects below. Just come to us with your vision and we can work with you to bring it to life.


This National Park holiday house was subject to a major rebuild by the Onsite Builders team. The clients’ desire was to double the existing living space and re-modernise while infusing the build with unique, quality features. The original structure was solid and worth retaining yet was fully stripped and re-reroofed with new joinery throughout. An addition, a mirror image of the original house, was built and the two joined together by a clever link. 

This was a project that demanded successful execution of a extensive range of construction skills working with features such as T&G ceilings, jarrah flooring, Neuraply roofing, riverstone foundations and fireplaces, greenheart decking and tiled bathrooms. A detailed build achieving an exceptional result.


This 100 year old cabin was originally built by settlers off the coast of British Columbia and was verge of ruin when Steve was enlisted to restore it back to it’s former glory. A genuine restoration project, the brief was to preserve as much of the original timber structure and features as possible while bringing the cabin into the 21st century, fit for guest accommodation. Every detail of the project was carefully considered and demanded good old fashioned carpentry skills combined with a Kiwi “can do” attitude.

Cedar shingles on the outside, reclaimed hardwood floors on the inside and vaulted ceiling (including the original roof structure), this cabin has been given a new lease of life while retaining its historic character.


Here, an addition to a 100 year old Kauri villa achieved a seamless result. Using traditional design features and materials such as the extra wide band-sawn timber sourced for the weatherboards, the style is classic and timeless. Wooden framing and sills around the aluminium joinery gives the windows the appearance of being original. Detailing around the soffits and barges add to the effect. The house gains a garage and bedroom space all the while being sensitive to the historic origins of the existing home.


The original house had good bones but was cold and due for a re-clad. The Onsite Builders team were enlisted to turn this around and the result is a house which is almost unrecognisable from what it once was. The old cladding was determined to be asbestos which was organised to be professionally removed and disposed of in accordance with government regulations.  This was replaced with board and batten cladding, insulation inserted with new double glazed windows replacing the old. New doors were installed where a window once was and now opens out onto a deck. It is now a warm, dry house and for a fraction of the price of building new.


This project is a wonderful example of a simple re-clad bringing a new lease of life to a tired exterior. Rather than a standard pine ply and batten cladding, the client opted for a cedar-faced ply stained with high quality oil. The raw grain of the cedar ply elevates the overall look beyond that of standard board and batten. A fantastic look.


Here a new lounge and dining extension is seamlessly integrated with a traditional weatherboard home. With mountain views to be taken advantage of, picture windows and an outdoor living space were a must. A freestanding fire with a concrete hearth made by Steve acts as a focal point in the lounge. Covered in decking extends the living area creating more space to relax and entertain.
