Curved Deck Builder in the Louisville Metro Area

A curved deck softens the transition between the home and the yard, follows the property’s natural contours, and creates a shape that feels intentional rather than imposed. Every SunnySide curved deck starts with a 3D model, so the radius, framing layout, and board direction are confirmed before a single post is set.

WE’RE TRUSTED BY:
A curved wooden frame and structural supports for a large deck or balcony under construction. The framing consists of multiple parallel wooden joists that form a semi-circular shape. The wood appears to be treated lumber. This wooden structure is supported by a frame of black or dark metal beams and vertical posts anchored to the ground, possibly with concrete footings visible in the lower right.

Radius Framing

SunnySide’s expert curved deck contractors in the Louisville Metro Area frame every curve with angled blocking and custom‑cut joists, ensuring precise curved deck construction that matches the 3D model exactly.

  • Custom Joist Layout: Joists are cut and positioned to follow the curve’s radius, matching the 3D model exactly.
  • Blocking and Bridging: Additional blocking between joists supports the curved perimeter and prevents lateral movement over time.
  • Framing Materials: Selected based on the curve’s radius and load requirements, including Fortress steel framing, TimberTech/Azek, and KDAT lumber.
Outdoor deck at twilight. A built-in, curved seating area is the focal point, made of warm, reddish-brown wood that matches the decking. The seating is illuminated underneath by a subtle strip of warm LED lighting. It is furnished with light gray cushions and multiple throw pillows. The seating area is flanked by square wooden planters on both sides.

Surface & Board Layout

Board direction and cut angles are mapped within the 3D model before installation begins.

  • Straight Boards on a Curved Frame: Standard composite boards are cut at angles along the curved perimeter, with picture frame borders running the full curve.
  • Radius-Cut Boards: For tighter curves, boards are cut along their length to follow the curve precisely. This approach requires more material and exact cutting throughout.
  • Picture Frame Borders: Every curved deck includes a picture frame border that follows the full radius, defining the shape and protecting end cuts from moisture.

More Than a Shape. A Structural Decision.

A curved deck is not a standard deck with rounded corners. Every curve introduces framing complexity that must be resolved before surface installation begins. SunnySide addresses two core components on every curved deck project:

  • Radius Framing
  • Surface & Board Layout

Curved Deck FAQs

What makes a curved deck more complex than a standard deck?
Every curve starts in the framing, not on the surface. Joists have to be custom-cut and positioned to follow the radius; additional blocking supports the curved perimeter, and every board cut at the surface has to follow that curve precisely. It is significantly more work than a straight build, which is why most builders avoid it.
Straight boards on a curved frame are cut at the perimeter to follow the shape of the deck below. Radius-cut boards are cut along their length so the board itself follows the curve. Radius-cut boards are used on tighter curves where straight boards cannot make the bend without creating gaps or misalignment at the surface.
What composite brands work best for curved decks?
All of SunnySide’s composite lines are available for curved builds, including Trex, Deckorators, TimberTech, Fiberon, MoistureShield, TruNorth, and Evalast. The right choice depends on the curve’s tightness and the specific design’s cutting requirements.
Yes. Every SunnySide deck includes a picture frame border as standard, and on a curved deck, that border follows the full radius of the curve. It defines the shape cleanly and protects the end cuts from moisture.
