The carefully designed two-storey rear extension and two-storey side extension were created to meet specific requirements, including two bedrooms, a kitchen, a utility room, an ensuite bathroom, and a separate WC. The design incorporates a single-storey element to the rear with a catsliding roof and a rooflight positioned above the dining table to adhere to the 45-degree rule in relation to the neighbor's window. The rear extension spans across two levels and features a single-storey element. This section includes a catsliding roof design, which slopes in a particular way to meet regulations and ensure compliance with the 45-degree rule. This architectural feature allows the extension to harmoniously blend with the neighboring property while maximizing natural light and aesthetics. Additionally, a rooflight is strategically placed above the dining table, providing ample daylight and creating an inviting atmosphere. On the ground floor of the rear extension, a well-designed kitchen is incorporated to cater to the culinary needs of the occupants. Adjacent to the kitchen, a utility room offers practical space for laundry and additional storage. Moving to the upper level of the rear extension, two bedrooms are provided to accommodate the residents. One of these bedrooms includes an ensuite bathroom, providing convenience and privacy. The two-storey side extension complements the rear extension and is designed to accommodate the remaining bedroom, as well as potentially other rooms as required by the occupants. To ensure compliance with regulations and maintain a respectful distance from neighboring properties, the design takes into consideration the 45-degree rule in relation to the neighbor's window. This rule ensures that the extension does not obstruct the neighbor's views or encroach on their privacy. Overall, the two-storey rear extension and two-storey side extension provide the necessary space for two bedrooms, a kitchen with a utility room, an ensuite bathroom, and a separate WC. The inclusion of a single-storey element to the rear with a catsliding roof and a rooflight above the dining table showcases a thoughtful design approach that adheres to regulations while creating an attractive and functional living space.
