Summary
Brought to life a multi-use layout designed by landscape designer. Our scope was to evaluate, reinforce, and fully enable a roof space for private recreation and entertainment use with an outdoor kitchen and dining area.

Description
The firm provided design and consulting services to enable a new, modern program.Our scope was to:

Replace the old skylight with an expanded, flat & walkable one over the living space,
Provide structural modifications to accommodate a new deck, fence, planters, retractable awning, and pergola design,
Evaluate feasibility of adding plumbing and gas connections, and incorporating those connections to create an outdoor kitchen.

Keeping the roof opening the same, we designed a walkable skylight that is flush-mounted with a raised ipe deck. Our structural evaluation was accomplished with minimal invasiveness by creating microprobes and confirming the existing roof’s load-bearing capacity before getting started.

The final roof area was terraced into a raised seating area, outdoor kitchen covered with a wind-sensing retractable awning, dining area, and pergola.
