Challenge

Our clients wanted to transform their two-bedroom detached house into a home suitable for their large family, aiming to double the property size with a substantial extension. The house, situated on a corner plot with significant external space, posed a challenge, as councils often prioritise preserving the openness of such plots to maintain the neighbourhood character, especially in suburban areas. Consequently, convincing the planning officers that a large extension would be beneficial wasn't going to be easy.

Approach

We proposed a radical design solution that avoided overwhelming the original building by creating a symmetrical appearance from the front, mirroring the existing design to blend with the neighbourhood. This strategy aimed to persuade the planning officers that the two-storey extension would not constitute over-development or negatively impact the streetscene, while radically transforming the interior to meet the clients' needs.

Solution

The design doubled the property's size from 79 sqm to 172 sqm, creating ample space for family leisure activities, with fully renovated bedrooms featuring en-suite bathrooms, jacuzzis, and walk-in wardrobes. We also designed an indoor swimming pool with stunning open-plan interiors, which took the property to another level.

Before & After

Architectural floor plan of an existing ground-level house, featuring a detailed layout with labeled rooms, furniture placement, and clear indications of doors, windows, and staircases, presented in a high-contrast monochrome design for easy readability and professional use.
