A high level of consistency, critical to the final appearance of the project, has been achieved. The final appearance of the cleaned and repaired sandstone tracery to the Quadrangle is particularly pleasing for its sensitivity to the historic value of this stonework.”

West Haybogs

“They provided an excellent survey service and liaised with my architect and local authorities to determine an honest and sympathetic scheme. They performed a rigorous historical analysis in the context of my intended conversion and produced an excellent report complete with photographs and detailed advice on finishes. I was slightly apprehensive at the outset that their approach was aimed towards the very top end of the market however this proved completely unfounded. Their fee was very reasonable and in my case the pragmatic and honest scheme they proposed dramatically reduced construction costs, in addition to adding value to the finished product. I would strongly recommend that anyone involved in property development use LTM, whether it be a small cottage or a medieval castle.”

Nick MargiottaClientWest Haybogs

Steven Laing carving stone

“My journey as a stone mason with Historic Scotland at Elgin Cathedral deepened my appreciation for craftsmanship and history. Since founding LTM in 1999, we have completed over 1,000 repair and restoration projects — each one a reminder of the importance of expertise, craftsmanship and respect for the materials that define our historic structures.”

Steven Laing Managing Director
