Architectural Design & Build · Cornwall
Spaces designed with care.
Built with intent.
From the first sketch to the final handover — bespoke homes, extensions and remodels across the whole of Cornwall.
A studio in Cornwall
Trademark Designs is a design and build studio based in Goldsithney, specialising in residential extensions, new builds and remodels, providing a cost effective solution for homeowners across Cornwall who want a single, trusted partner from drawings through to completion.
We draw and submit plans, navigate planning permission and building regulations, and — when you're ready — manage and deliver the build itself. One studio. One conversation. From design to keys in your hand.

"It is so rare to find an honest tradesman like Adam. He worked consistently, finished on the day he said he would, and the finish was great. I couldn't recommend him enough."
"Adam produced a job that was 110% perfect. On time, polite, hard working, economical and handled some unexpected extras without issue. I will certainly ask him to work for me again."
"Punctual and reliable, arriving when he said he would and working a full day. Finished to a high standard and great value. I would happily recommend him to others."
