Proposed Option I Design (Straight, wooden-based) - elevation studies, floorplan & internal views

Design Process

The design was a collaborative process, with various design studies aimed at establishing various layout configurations, roof geometries, discussing construction methods/ materials, discuss and helping the family prioritize the practicality of the space and other considerations. Through online and in person workshops, we discuss, compare, mix & match, measure ''live'' on the floor and initiate discussions of initial material pallette studies, for both the interior and exterior.

Existing Site

The existing side had an existing rear extension. The proposed works aimed at changing the ground floor into an open plan for living/ dining & cooking, infilling the side and relocating the mature olive tree. Currently, the inner garden is facing south and it is in most of the cases sunlit. The proposed new extension is looking at introducing two skylights to allow for deep floor light penetration, bifold glazing to allow for complete opening up during summer.

Butterfly Roof

The proposed roof would include new skylights and bespoke gutter box to allow for smooth and clear view as seen from first floor. The new warm roof would end in GRC pannels.
