Gwennan Josh Design Studio can't wait to hear about your project or idea, so please get in touch and 'Say Hi!'



'Consultation' sounds quite formal don't you think?... I like to think of them as a chat with a nice cuppa!

We will discuss your ideas for your project, whether interiors or illustrations

and together we'll define your brief and identify your budget.  We'll also agree on the scope, timelines and fee, so that you know exactly what to expect throughout the process.

Consultations are online and free of charge, so get in touch,'Say 'Hi' and let's get the ball rolling...

Interior Design & Specification 

Your dream space is just a few steps away...  my pre-start workshop will help define your likes and dislikes, I will then create a moodboard with 2D layouts to give you a sense of what your space/s will look and feel like.


Once agreed, I'll provide detailed sketches and product specifications to ensure that your scheme is executed with precision and care by your contractor.


Let me take the hassle out of designing your space and CREATE YOUR NEW interior that exceeds your expectations.

For all commercial related projects, please get in touch for more information.

Furniture & Accessorising

Accessorising your space can take a lot of thought and time, so why not let me do the planning and specification for you. 

I can provide options on a moodboard with 2D location drawings, which means that you can put the finishing touches on your spaces personally.


Illustrations & Graphics

Gwennan Josh illustrations and graphic design services for print and online media, add colour, fun, and energy to any project.


Drawing Styles

I'm a bit of a Pointilist at heart, but whatever your prefered style I would love to learn more about your project and discuss your needs.


I can create artwork in different styles and mediums:

I use the digtal artwork for those bold, colourful statements and for more delicate artwork I use pencil or ink, usually black and white with a splash of colour to make it POP!
