A  builder on the New Jersey shore was building an exceptional home for a client. To provide access to the 2nd and 3rd floor deck on the back of the house, the architect had designed two flights of double helical stairs This gave the visual impression of a stacked double helical staircase. We created the inside and outside stair stringers from ¼” high grade aluminum sheet. We added a 1” x 1” trim detail at the top and bottom for visual appeal. This not only gave it awesome aesthetics, but great structural and rigidity as well. We created the double helical stair treads  from high grade aluminum sheets and formed them to the correct outline so they would accept the wood treads.

The stair railing design called for ½” round stainless rods installed horizontally, finished to a #4 brushed finish. We created the stair railing structures from aircraft grade aluminum. We attached this directly to the top of the double helical stair skirt. The railing posts were 1 ½” square material, with intermediate verticals being 3/8” X 1 ½” to support the stair railing horizontals.

We built the caprail to be 2 ¼” wide with a molded profile. Then we powder-coated the two double helical stair structures a sea shell white. Next, we inserted the ½” round stainless rods through the holes in the stair railing posts. Then, we tig welded the horizontal rods together. We fixed the railing rods into place with a dab of epoxy in the post’s holes. 

The transportation to the installation site was completed in 2 different trips due to the size of the double helical staircases. To help the men install this big project a crane was set up onsite. One by one the crane lifted the stairs into the exact location, and we attached them into place. Both of these double helical stairs enhance the architecture on the back of this New Jersey shore home, and can now provide comfortable access to the 2nd and 3rd floor decks.

Thanks to the Compass team. The original work that was done 12 years ago still looks great. Unfortunately, we had to remove the railings to install new pillars this year due to weather related issues with the stones. Compass removed the rails and reinstalled them after the repairs were done. All looks beautiful again.

We were thrilled to work with Compass again on our back porch project! The end result is gorgeous and the process was seem less. In a time characterized by delays, labor shortages and supply chain issues, Compass exceeded our expectations by providing a beautiful product and outstanding service in a timely manner. We look forward to working with Compass again in the future on all our metalwork needs.

Thank you so much again for your help!

Compass was very flexible when we changed our design. Quality was so wonderful, and unexpected.
We would never go to anyone else.

Amos, your team exceeded extremely high expectations. The stairs are the heart and soul of the house, and as the main focal point are a treasure to the owners and architect. Every visit is followed by “come see the stairs”. I know how challenging it was to build and install this masterpiece, having worked as a builder for 50 plus years, and admire how your crew stayed positive and focused throughout. I can’t wait for the next one!
