What does it take to expand a home by 1,000 square feet mid-build for four generations on a fixed budget?
In this AIA Austin Homes Tour edition of TALKdesign, Adrian Ramsay tours Twin Oaks, the personal residence of architect Vani Singal (AIA, NOMA, NCARB), Founder and Principal Architect of Workshop No.5.
When Vani bought a property centered around a 160-year-old live oak, the initial plan was straightforward. During the pandemic, however, her family's needs shifted, and the project grew into a multi-generational home for four generations. Vani explains how hand-deconstructing the original house allowed them to salvage brick for the new facade and how five custom window "periscopes" pull natural light and tree canopy views into the interior.
We discuss the practical details of designing homes for aging family members, including low-level kitchen storage, zero-entry bathrooms, and logical floorplan circulation. Vani also shares how specifying James Hardie siding gave the exterior a clean metal appearance while adding 1,000 square feet during permitting without exceeding the construction budget.
💡 What we cover in this episode:
• Preserving the 160-year-old Live Oak and reusing hand-deconstructed bricks in the new facade.
• Designing five pop-out periscope windows inspired by childhood toys to bring light and sky views indoors.
• Creating clear pathways, accessible low kitchen cabinets, and zero-threshold bathrooms for older family members.
• Using smart siding details to add 1,000 square feet during permitting within the original budget.
• Combining Indian terracotta, terrazzo, and Portuguese blue tiles to reflect family heritage.
