You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.
Tenby
Tenby is a walled seaside community in Pembrokeshire, Wales, on the western side of Carmarthen Bay. Tenby is a local government community. Notable attributes include 2 1/2 miles (4.0 km) of sandy beaches and also the Pembrokeshire Coast Course, the 13th century medieval community walls, consisting of the 5 Arcs barbican gatehouse, Tenby Museum as well as Art Gallery, the 15th century St. Mary's Church, and the National Trust's Tudor Merchant's House. The town is offered by Tenby railway station. Boats sail from Tenby's harbour to the offshore reclusive Caldey Island. St Catherine's Island is tidal and also has a 19th century Palmerston Ft. With its strategic setting on the much west coastline of Britain, and also a natural protected harbour from both the Atlantic Sea and also the Irish Sea, Tenby was an all-natural settlement point, most likely a hill fort with the mercantile nature of the settlement perhaps developing under Hiberno-Norse impact. The earliest recommendation to a settlement at Tenby is in "Etmic Dinbych", a rhyme probably from the 9th century, maintained in the 14th century Book of Taliesin.
