In this second blog post, we show how Machan Engineering can work with architects on specialist regeneration projects in historical settings and to tight budgets. And we look at how Machan Engineering can come up with inspired solutions to specifcation problems.

Edinburgh-based architects Smith Scott Mullan Associates received a commission from Dumfries & Galloway Council to transform Stranraer into a marine leisure destination following the closing down of the Stena Line service from the port. Part of the regeneration masterplan was a route that followed the Town Burn (a small stream running through Stranraer), connecting the seafront with Castle Square in the historic town centre.

As part of the re-design of the external landscaping in Castle Square, which surrounds the historic Castle of St John in the heart of the town, new tree grilles and tree guards were required. Architect Sarah Barron of Smith Scott Mullan contacted Machan Engineering – a company whose products she had successfully specified on several other occasions.

Given the sensitive historic setting, it was important that the hard landscaping looked just right. Machan initially quoted for stainless steel units, but eventually it was decided that cast iron grilles and guards would be more suitable to the project’s budget. The cast iron was painted black, making it blend in with the look of the Castle and the Square.

When the time came to install the tree grilles, it transpired that too small a gap had been left for them in the freshly laid stone paving. Rather than having to go to the expensive step of manufacturing smaller grilles, Machan came up with an inspired solution: the outside flat bars of the grilles’ support frames were removed to make their footprint smaller, and the frames were instead strengthened using supports and tags that would be invisible when installed. The re-engineered grilles fitted beautifully into their allotted spaces.

Dumfries & Galloway Council received robust, well-made products that came within their budget.

Smith Scott Mullan won the Scottish Design Award for Public Realm & Landscaping (2012) for the Castle Square project. In 2011, the project also won the Saltire Society Arts and Crafts in Architecture Awards – the first time in four years that the full award had been given.
