This project was a tribute to women’s hard work which stands at the approach to Dunbar Harbour. Dunbar Shore & Harbour Neighbourhood Group sought the views of the public for a traditional stone sculpture on the site.



Requirements needed for the course of this project included tumbled course walling, tumbled split faced and ashlar finishes, sawn and sandblasted paving, external steps, ball finials, and tapered columns were manufactured for the exterior.

  • “I certainly made the right decision getting new granite worktops from Calvert’s. They look fantastic and the pricing is competitive. The whole process from start to finish went without a hitch and in a very short time frame. The staff were all pleasant and knowledgeable and could not do enough to make sure everything was to my satisfaction”
  • “In 2018 A. D. Calvert Architectural Stone Supplies Limited designed, manufactured and fitted hand crafted bespoke stone patient parking signs for outside the Dales Central Practice Doctors Surgery, Aysgarth within the Yorkshire Dales National Park. The stone signage was kindly donated in support of the local community to help alleviate parking problems. The quality of the stone and workmanship was beautiful and in keeping with the landscape of the village and local area.”
  • “When I recently had my kitchen refitted I decided to engage the services of A.D. Calvert Stone Supplies Ltd., to supply and fit the granite work, having been made aware of their outstanding reputation. I was extremely pleased with the exceptional quality of the South African granite which Andrew Calvert went out of his way to source for me, to complement the chosen design scheme.”
  • “From our experience over many years of working closely with AD Calvert to supply natural stone walling, paving, and masonry to the Construction Industry, there is no better quarrying and manufacturing company. The production facilities, organisation, professionalism, and above all the reliability in terms of quality and availability are second to none. The hands-on approach and technical expertise of the owners instils confidence throughout the whole process.”
  • “Witton Fell is a great sandstone to use for large scale public sculpture. It is a tough durable material. It is available even in massive block sizes, free from cracks, drys, fissures and vents. The people at Calverts are really friendly, patient and helpful. They all understand the rough, tough nature of working with sandstone. The guys in the quarry seem to have a knack for ‘getting’ an idea of the sort of a bit that you are looking for and keeping an eye open for a block of the right shape and size. They are skilled at identifying and keeping track of the natural bedding plane of their blocks and making sure that you understand how best to use it. The management are supportive and understanding. It has been a pleasure building up a working relationship with the team, the quarry and the area over the years.”
  • “Taylor Maxwell are delighted to partner AD Calvert whom we continue to work closely with. The quality of service and product we receive is first class whilst having our own personal contact in Jonny, this really helps us keep the end user happy throughout our projects.”
  • “As a designer, having craftsmen like Calverts in our locality really does broaden the possibilities for creative solutions in our schemes.To work with them is to experience the traditional craft of forming stone while also tapping in to what is quite literally at the leading edge of stone-cutting technology. Having visited their premises, the ways in which I can use stone in my projects has increased exponentially! Great product and great service.”
  • “I had the hearth installed this morning and I'm absolutely delighted. Thank you so much for delivering it so quickly and for the excellent customer service throughout. It's so nice dealing with such a professional company and receiving such a great product.”

  • “If its excellence you are looking for then look no further. We searched high and low for a company to provide us with granite worktops that would compliment our wonderful bespoke made kitchen.”
  • “Would just like to say that we are very pleased with the two sets of steps, the whole process from computer aided design to the final product went very well. We are delighted with them, now that they are installed. We will recommend you.”
