Custom Designs

We bring our experience and skills to solve any kind of engineering and design challenge.

Our alchemists enjoy turning their hand to a wide variety of special projects including cable cars, letterboxes, louvres, marine applications, outdoor furniture and architectural structures.

And of course we custom-make any kind of balustrade, fence, handrail or gate to meet your needs and specifications.

Cable cars

Cable Cars

We manufactured this oriental boat-themed cable car for one of our partner companies for use in an exclusive resort in Asia. It’s constructed of a sturdy frame comprising of round and square stainless steel tubes in a brushed finish.



We can make letterboxes to suit any style of home. Here’s one we made to complement a modern residence using aluminium plate and laser-cut numbers, all with a powder coat finish.



Our powder coated aluminium louvres in white add a stunning statement to this stylish décor. They divide living space and bedrooms in this guesthouse, and close fully to offer total privacy. We also manufacture and install louvres for commercial premises.

Marine applications


This job started from a sailor's sketch on a scrap of paper. The client’s requirements were for a high-strength, durable but lightweight bracket for a catamaran. We used marine grade 316 stainless steel sheet and fixings for this intricate job, manufacturing most of the components in-house.

Church bell


We took delight in refurbishing this historic church bell from the 1924 Our Lady Star of the Sea Convent Chapel overlooking Seatoun. Above the bell you’ll see the marine grade 316 stainless steel running gear we restored, most of which we custom-made in-house.

Outdoor furniture


A smart and durable set of outdoor furniture that comprises marine grade 316 stainless steel frames and stained taun hardwood tops. Its dimensions can be made to order.



We can design, manufacture and install any structure that either seamlessly integrates with the style of your home or garden, or provides true definition and contrast to stand out as a statement and talking point. Alchemy installed this attractive pergola and balustrade for a Hutt Valley home using powder coated aluminium with hardwood slats.
