The firm’s flagship Prestonfield branch has been upgraded to improve the customer experience across the site.

The overhaul includes an enlarged hard landscape section which now features improved options from composite decking and cladding through to glass balustrade, porcelain, sandstone, walling and paving.

Established in 2002, St Andrews Timber & Building Supplies is one of the largest independent builders’ merchants in the central belt of Scotland and Monday’s event will also see the launch of a brand-new digital landscaping brochure.

Door and floor displays have been renewed as part of the showroom improvements, with a brand-new acoustic wall panels section having also been erected.

The festivities run from 10am until 2pm, and with a bouncy castle, face painting, crazy golf, raffle and free giveaways, there will be something for the whole family.

Richard Harley, Prestonfield office manager, said: “The upgrade to Prestonfield is long overdue and we’re confident it will be well received by the trade and public. I think it’s fair to say it hasn’t been the most customer-friendly premises and we have addressed that with the changes that have been made.

“Over the years the displays and the showroom itself have become quite tired-looking. The place is going to have a much more modern feel to it and the experience is going to be so much more enjoyable for the everyday DIY person as well as the trade customers.

“We have brought Prestonfield’s displays, shop floor and overall look and feel in-line with the rest of our more modern branches across Scotland.”

As well as Prestonfield, the company also has branches in Stenhouse in the capital, Paisley and Livingston.
