Wood saws, teaspoons, musical instruments and even spark plugs are given new life in works that range from jewellery items to indoor and outdoor furniture.
His talents have caught the attention of Shed magazine and his photo graced the cover of the edition he featured in.
The Shepherds live a few doors down from the gallery, which they opened in February this year.
"The house previously belonged to glass artist Kathryn Wightman and this was her workshop," says Debby.
"It was already a good space for a gallery - it just needed lightening up with new paint on the walls."
The Shepherds have plans to extend the gallery to the outdoor area which lends itself to displaying Peter's furniture and sculptures.
"I would like someone to park their coffee cart out there too," says Peter.
"There's plenty of space and we get the traffic heading to and from the State Highway."
They also want to encourage pedestrian traffic and Debby says there are a lot of dog walkers going by.
"We see people hesitate and look in the windows but they have dogs with them.
"We want to attach some hooks to the front of the building for tying leads to and maybe even offer dog treats so the owners can come in and have a browse."
The couple also want to encourage more artists to share the gallery space and, Debby says, a glass artist or two would be especially desirable.
"If we have more artists in our collective, we could open for more hours and that will be great."
The Red Door Gallery, 88 Putiki Drive is open from 11am to 4pm, Friday, Saturday and Sunday.
