Huntington's moraine lots rarely offer a flat place to put a deck, and the single large platform the catalogs assume becomes, on a slope, a stilted shelf hovering over a hillside. The design that works here steps with the grade: a series of levels, each modest, connected by short stair runs, landing where the hill lands.
Why multi-level beats one big platform on grade
- Each level sits closer to its ground, so the structure stays honest — shorter posts, less bracing theater, guards where guards are needed and open edges where the drop is a step
- Levels zone themselves: cooking on the house level, dining a step down, a fire or spa terrace at grade — circulation the hill designs for you
- The lowest level often stops being deck at all and becomes patio — the deck-to-hardscape handoff on the downhill side is the signature north-shore move, and we build both sides of it
- Cost scales honestly: three modest levels usually price near one tall platform, because height is expensive and steps are not
Building around oaks, not through them
Huntington's mature oaks are worth more than any deck, and a slope lot's best trees are frequently exactly where the deck wants to go. Framing around a trunk — a generous well, not a snug collar, sized for decades of growth and trunk flex — keeps the tree and gains the shade. What matters underneath: footings placed off the critical root zone, hand-dug where the roots run, because pier holes through structural roots kill oaks on a five-year delay nobody connects.
The jurisdictions, as always
Huntington Bay, Lloyd Harbor and Asharoken run their own desks, and visible structures on harbor-side parcels get reviewed accordingly. Parcel check first; drawings to the right authority; the slope survey that the multi-level design needs anyway doubles as the permit exhibit.
Frequently Asked Questions
My back yard slopes away hard. Can I still have a deck?
Yes — but the design that works steps with the grade instead of fighting it: a series of modest levels connected by short stairs, each close to its own ground, often ending in a patio at the bottom. It zones itself naturally, the structure stays honest, and three stepped levels usually price near one tall stilted platform because height is expensive and steps are not.
Can you build a deck around my oak tree?
Yes, and on a Huntington lot it is often the right call — the tree is worth more than the deck. The framing gets a generous well sized for decades of trunk growth and flex, and the footings go off the critical root zone, hand-dug where roots run. Pier holes cut through structural roots kill oaks on a five-year delay; we plan the foundation around the root map first.
How long does a deck take to build?
Five to eight days on site for a typical 300 to 500 square foot composite deck, after permit approval. The permit is the calendar driver — most Suffolk towns require one for any attached or elevated deck, and lead times vary by town.
Do I need a permit for a deck on Long Island?
Almost always, for anything attached to the house or elevated. Incorporated villages run their own desks with their own timelines. We handle the drawings and filing as part of the job, and we confirm which authority governs your parcel before quoting.
