Our personal approach ensures our clients’ requirements are understood and their designs brought to life – a complete service from concept to display.

From our studios here in Cardiff, we create a wide range of bespoke props tailored to our clients’ schemes and requirements.

We thought we’d share these wonderful images of a Valentine’s Day display created for The Shard by Lorella Designs a few years ago.

Lorella Buizza transformed our polystyrene bears with artificial red roses. Standing 5ft tall and positioned on the 72nd floor of The Shard in London, they certainly made an impact.

Taking a look back at this Christmas project for the National Trust Oxburgh Estate from last year.
We produced these decorative snowflakes from recyclable Re-board, which was a great material choice for the National Trust when looking for a more sustainable option.
Lightweight and supplied with a hanging point, the snowflakes worked really well in the space.
With Christmas already getting closer, now is a great time to start planning your displays.

One of the benefits of manufacturing in-house at Graham Sweet Studios is that we're involved in every stage of the process, allowing us to develop ideas, test different finishes and refine the details as a project progresses.

When it comes to our bespoke 3D letters, this means we can explore different finishes and techniques, from painted, metallic and glitter finishes to wood, stone and concrete effects, creating the right look for each individual project.

Here are just a few of the 3D letter finishes we've created over the years. Do you have a favourite?

With the Royal Welsh Show taking place this week, we're looking back at these colourful 3D letters we produced for the event a few years ago.

Standing at 1800mm high, the 'Y SIOE' letters were manufactured from expanded polystyrene, coated for added strength and finished in bright colours to create a striking focal point.

It was great to see the finished letters in place, providing visitors with a colourful backdrop and a fantastic photo opportunity.
