What’s Possible
Custom Colours
Personalise your hardware with custom powder-coating in your choice of colour — including shades from Dulux and Interpon — to perfectly complement your project’s palette.
Custom Sizing
Select ranges can be tailored to your exact dimensions, with lengths of up to 1200mm. Whether scaling up for impact or refining for subtlety, our custom sizing ensures a seamless fit.
Bespoke Design
For projects that demand something truly unique, we offer custom materials, specialist finishes, and tailored design solutions. Whether you're seeking a statement texture, distinctive metalwork, or something entirely original, our bespoke service ensures every detail is exceptional.
Innovation Meets Craftsmanship
At Castella, we believe great design happens when creativity meets expertise.
Our custom work is proudly shaped by our network of Australian artisans — makers who bring extraordinary skill to timber, metal, and finishing techniques. This commitment to craftsmanship is reflected in partnerships like Tasmanian Hydrowood, a rare reclaimed timber that combines sustainability with striking natural beauty.
For projects requiring specialist techniques, we also collaborate with some of the world’s finest makers — from Italian sandcast bronze specialists to precision brass artisans in India’s most skilled foundries.
Wherever your vision takes you, Castella’s custom services combine local craftsmanship, innovative materials, and global expertise to bring it to life.
Let’s Make Something Exceptional Together
Wherever you are in the process — whether refining concepts, finalising CAD drawings, or ready for production — our team is here to support you at every stage.
