Sit Close to the Yard — Without Sitting in the Damp
Ground-level and platform decks that skip the stairs and railings but never skip the drainage. The whole game this low is keeping the frame off wet ground and letting air move underneath — get that right and a low deck outlasts the house.

Signs to watch
Is this you?
You want outdoor living without the stairs
A ground-level or platform deck steps straight out from a slider onto grade — no stairs, and often no railing required when it sits low enough. It's the simplest way to add usable outdoor room, and in most jurisdictions the lightest on permitting, though we verify the local threshold before we build.
The old low deck rotted from underneath
Low decks fail from below, where framing sits inches off damp ground with no air moving through. If your last one went soft in a few years, the cause was almost always poor clearance and drainage — not bad luck — and it's exactly what we design out.
Water pools where the deck meets the yard
Standing water at the transition from deck to lawn or patio keeps the framing wet and feeds rot at the perimeter. Grading, gravel, and the right ground clearance move that water away instead of letting it sit against the wood.
A patio pad you've simply outgrown
A concrete pad is fine until you want a level, splinter-free surface that flows off the house. A platform deck over or beside it adds real square footage low to the ground at a fraction of an addition's cost.
Your options
Everything that matters on a low deck happens underneath it
Because the frame sits close to grade, moisture control is the whole job. We build on engineered footings sized to the soil, keep the framing up off the dirt with proper ground clearance, and use ground-contact-rated lumber wherever wood lives near damp. Drainage comes first — grading and gravel so water sheds away instead of pooling under the boards — and we leave the underside open enough for air to move, because a low deck that can't breathe rots from the joists up. Surface can be capped composite for the low-maintenance the PNW rewards, or cedar when the budget or feel calls for it, with the upkeep schedule in writing. Footing depth, framing clearances, and whether a railing is required all depend on how high the deck sits and your local code, so we confirm the specifics on site rather than quoting a number from a chart.
The method
How we do it
- 01
Site, drainage, and grade review
We look at how water moves across your yard and where it collects, then design the deck's footings, clearance, and drainage so the ground underneath sheds water instead of trapping it against the frame.
- 02
Footings and framing
Engineered footings sized to your soil, framing held up off the dirt at proper clearance in ground-contact-rated lumber, and the underside left open enough for air to circulate.
- 03
Surface and walkthrough
Decking set with hidden fasteners, edges and transitions detailed to shed water, then a walkthrough of the finished deck and the care schedule for whichever surface you chose.
Straight numbers
What a ground-level deck runs
Low decks are usually the most affordable to build — no tall posts, stairs, or railings to engineer — so the number is driven mostly by square footage, surface material, and how much site and drainage work the ground needs. Composite costs more up front than cedar and gives it back in maintenance you skip. A yard that needs regrading or gravel to move water adds to prep. We'll price the deck and the groundwork it actually requires, not a bare square-foot rate that ignores the drainage that keeps it alive.
Where we do this work
Ground-Level & Platform Decks: straight answers
Do I need a permit for a low ground-level deck?
Often not, if it's low enough and freestanding — many jurisdictions exempt decks under a set height that aren't attached to the house. But the threshold varies by city and county, so we confirm your local rule before building rather than assuming. An unpermitted deck that needed a permit becomes your problem at sale time.
Why do low decks rot so fast around here?
Because the framing sits close to constantly damp ground with little airflow, and our climate keeps that ground wet most of the year. The fix is clearance, drainage, and ground-contact-rated lumber — holding the wood up off the dirt and letting air move underneath so it can dry between rains.
Can you build a platform deck right over my old concrete patio?
Often yes, and it's a clean way to reuse a sound pad. The details that matter are keeping the new framing off standing water and preserving drainage so water doesn't get trapped between deck and slab. We look at how the pad drains before deciding to build over it or beside it.
Does a ground-level deck need railings?
Usually not once it sits below the height where code requires a guardrail — that's part of the appeal of building low. The exact trigger height depends on your jurisdiction, so we confirm it on site. If you want a rail for looks or to define the space, that's a design choice, not a requirement.
