Approximately 1300 yards of concrete were used throughout this uncommon residence. Concrete was used for the tennis pavilion, an underground tunnel to this pavilion, benches, planters and stairs as well as the supporting structure. Only a small portion of the home can be seen from the outside; thus the need for sulfate resistance. The concrete walls, floors, and ceilings show a wood appearance created with white pine forms.
40% slag was used in all the concrete. Several mockups were used to ensure the right workable mix ensuring no bug holes. Many homes in the Hamptons are built with wood shingles which do not hold up to the salt exposure and freeze thaw of winter and the threat of impacting storms was also a large concern for the owners. Slag was used for sulfate resistance which added winter durability and strength against hurricanes.
This home sits between the Shinecock Bay and Atlantic Ocean where the views are spectacular. Added strength facilitated by the slag allowed the architect to maximize the views by designing long spans through the use of post-tensioned and high-strength concrete. The use of these long open spans also maximized the view of the water.
