The firm wants to build a 100-bed hotel and 80 holiday homes near Llandeilo in Carmarthenshire to attract international tourists – mainly from China.
Maxhard, which has offices in London and China, said it would be a “luxurious development for a select international clientele looking to enjoy a tranquil Welsh retreat”.
The firm added: “The development proposed… will deliver a new, upmarket tourism concept which, as part of a large tourism enterprise will attract an international clientele, mainly from China.”
