About Us

Over 40 years of quality products and happy customers.

Early Years

Warwick Kendon founded Sellwood Products in 1976 with a core business of supplying and installing spiral staircases and shower doors. When first shown folding attic ladders in 1979, Warwick immediately saw the potential for providing homeowners safe, easy access to storage space in their roof, space they owned but could not otherwise access. Warwick bought a stand at the Auckland Home Show in 1980 and for the first time the New Zealand public saw folding attic ladders.

Made in New Zealand

For the next 20 years Warwick imported attic ladders from around the world, generating awareness and sales through Home Shows and word-of-mouth, all the while building a reputation for fantastic customer service. In 1998, the opportunity came to design and manufacture his own range of Sellwood Attic Ladders here in New Zealand. With an extensive knowledge of attic ladders from around the world, Warwick and his team set out to develop an attic ladder that was stronger and easier to use than its rivals. By April 1999, the first batch of New Zealand Made Sellwood Attic Ladders was available for sale.

Commercial Roof Access

Although initially focussing on residential customers, demand grew for a commercial grade solution. In the early 2000’s the heavy duty aluminium range was launched to provide access to storage areas, plant rooms and roofs of commercial buildings. The Sellwood integrated roof access system became recognised as the safest, easiest way for contractors to gain access to a roof. Dissatisfied with the quality of roof hatches available on the NZ market, Warwick and the team set about designing a superior roof hatch. The Sellwood Roof Hatch and Roof Hatch Barrier are now popular options for discerning architects, designers and building owners, helping them meet their Health and Safety obligations.

Moving Forward

Today, Sellwood dominates the New Zealand attic ladder market by providing the biggest range of quality attic ladders available. The product range has grown to include Skytube tubular skylights, LED Skylights and Gladiator garage storage. Despite the growth, Sellwood has not lost the drive for excellence, innovation and customer satisfaction. For over 40 years we have provided thousands of happy customers safe, easy access to their attic space and roofs. With Warwick’s son Russell now running the family business, Sellwood will be here for many years to come.
