Proficiency builders transformed their entire property in Twickenham by creating a large contemporary kitchen dinning area, leading onto the garden through the ultra-modern impressive glass doors. While the kitchen / diner represented the primary part of the job, we did not stop there. In addition to building the extension, Proficiency also converted the existing loft in to a larger bedroom with a dressing area and en- suite, we also renovated the rest of the house to a high spec.
