A home expansion project was strategized to incorporate a kitchen and bathroom adjacent to an existing bedroom. A distinct entrance was introduced to the extended space, equipped with contemporary kitchen and bathroom utilities, all achieved within a cost-effective framework. The client’s goal was to transform the extension into a self-sufficient area suitable for rental or personal use. The objective encompassed the integration of comprehensive kitchen facilities, a designated laundry space, refrigerator allocation, a compact in-built table within the kitchen area, and specialized cabinets for both modern and customarily designed storage. Careful consideration was given to the layout of pipelines, encompassing drinking water, hot and cold domestic water lines, exhaust systems, drainage lines, and electrical lines, including socket points. This meticulous planning aimed to ensure the provision of all necessary amenities within the constraints of a limited space.
