An £8 million expansion to a Leyburn auction house has begun.
The work at Tennants of Yorkshire Antiques & Fine Art Auctioneers, which is scheduled to take 54 weeks, will see the construction of three new salerooms and departmental areas.
It will also include galleries of display cases promoting items for forthcoming sales and two new enlarged restaurants. Chairman, Rodney Tennant, who opened the purpose built saleroom in 1993, cut the first sod.
He was joined at the ceremony by family members, staff and representatives of construction company ESH Build and architects Langtry Langton.
The programme of works has been designed in order that the sales calendar continues without disruption until opening in the summer of 2014.
