Project description:
Gorgeous, modern, concrete, steel, and wood residence with huge cantilevers. On the water in hurricane country.…
Notes:
Remarkable residence designed by award winning architects Hays-Ewing Design Studio. Features massive cantilevered roof in very high wind area. Extensive use of exposed concrete structural elements. The project required close coordination with all disciplines to achieve the architects vision.
Looking south. Previous structure has been demolished, and site is cleared.
Looking across the site from the South. Concrete work largely complete, garage area in foreground.
Site from West. tall concrete shear walls visible (with formwork to extend height in place.
Looking Southeast from future garage. Entry concrete wall to right, continues as concrete colonnade beyond. concrete shear wall ahead will separate kitchen from living room. Not thermal break material surrounding footing in foreground.
View back toward garage. interior concrete colonnade in foreground. two story concrete shear wall to left, entry concrete wall beyond.
View from southwest. three, two story concrete shear walls visible
Poor soils required compacted stone supporting concrete footings.
High-Density foam beneath footings serves as thermal break.
Elevated concrete beam formwork and reinforcing.
View from South. Structural steel underway. Beam on top of concrete wall beyond delivers lateral wind load to top of wall.
Moment Frame at south wing underway.
Yes it does snow in Virginia Beach!
Steel roof framing over great room with steel shade structure in place (painted white).
Topping Slab being placed in great room
Great room ready for topping slab
Ready for topping slab. Note diagonal bars at corner of concrete wall to limit slab cracking at re-entrant corner.
Slab is blocked out for future elevator.
Ready for topping slab. Structural slab cantilevers to left beyond rrightmost column.
Moment frame column at slab. Pipe sleeves will receive roof drain pipes.
Steel roof framing in place. Second floor structure is not in place yet. Note steel eave structures.
Cantilevered roof and shear walls. Second floor structure not yet in place.

Second floor framing at south wing.
Structural floor slab cantilevers over foundation wall.
View to west. Steel decking underway at north wing roof (to right).
South wing exterior walls, supported on cantilevered floor slab.
South wing floor structure beams
Roof and shade structures at north wing great room.
North wing roofs, viewed from south.
north wing second floor structure underway.
Entry hall low roof structure – connects north and south wings
View to south wing from great room
South wing cantilevered roof, with top of moment frame visible.
South wing floor structure
North wing second floor and roof framing at lower great room roof.
South wing floor structure to right, low corridor roof to left. Concrete shear wall in foreground, steel moment frame column in background.
Steel bridge beams connected second floors of north and south wing
Concrete colonnade and corridor roof, steel roof eave above.
A small but critically important part of the lateral force (wind) resisting system.
Second floor bridge structure connecting north and south wings
Moment frame supporting cantilevered roof of south wing. Actually a double cantilever; beam cantilevers over column, then main cantilever beam cantilevers 25 feet (!) off first beam.
