So you want to build a curved deck huh? There are several different methods but most of them are expensive and involve a professional unless you have the time and patience to learn yourself. In this post we will show you how to build a curved deck for under $200 in materials.

Curved deck frames require extra framing and support compared to a straight deck frame, but curved decks add an elegant look to any house. If you are building a curved deck, it is much easier the less curves there are in the design. For example, if there is only one curve, all of the diagonal measurements will be the same, which makes it easy to know where each joist is located on the frame. If there are multiple curves, then all of the joists will not be equal distances apart and that makes it more difficult to get your framing balanced.

  • Privacy enhancement: Provides visual barriers for outdoor living spaces.

  • Value addition: Increases overall property value.


Materials Used

  • Composite materials: PVC, composite lumber.

  • Wood options: Pressure-treated lumber, exotic woods (ipe, teak).


Building Considerations

  • Framing: Similar to straight decks with additional structure needed.

  • Joist support: Each joist must be properly supported at its ends.

  • Joist spacing: For an 8-foot radius, approximately 5 inches overhang per joist.

  • Center point measurement: Ensures accurate radius design.


Designing the Deck

  • Size and shape: Consider the lot and overall layout.

  • Material selection: Choose based on cost, durability, and aesthetic.


Construction Steps

  1. Choose materials: Base your choice on your design and budget.

  2. Build the frame: Follow the curvature without gaps.

  3. Lay out decking boards: Ensure they fit the curve perfectly.

  4. Attach railing posts: Install balusters for safety.

  5. Install railing caps: Finish off the deck with style.


Tools Required

  • Miter saw: Essential for cutting decking pieces.

  • Cordless drill/driver: Necessary for assembly.

  • Measuring tools: Tape measure or laser level for accuracy.

How to Build Curved Deck Stairs

Building curved deck stairs is no different than building straight ones, except that instead of using pressure-treated 2x4s, you’ll use 2x6s — or even 2x8s if you want to make them extra-strong. The same goes for the rails and stringers: Make sure they’re made from pressure-treated lumber or cedar.

As with any deck project, it pays to take your time when building a curved deck frame. You’ll want to measure twice before cutting once; check every measurement twice; and make sure everything fits together perfectly before driving any nails or screws into place.

In this video, we’ll demonstrate how to build a curved deck frame using pre-made parts.

A curved deck frame is an excellent way to add elegance and character to your outdoor living space. It can also be used as an accent feature in a corner or along the edge of your deck.

To build this type of frame, you will need the following materials:

2×4 lumber or 2×6 lumber – cut down into 2′ lengths (1 piece will be used for every step)

2×12 lumber – cut down into 6′ lengths (1 piece will be used on each side of every step)

How to Build a Curved Deck Frame

A curved deck frame is an attractive way to add architectural interest to your outdoor living space. A curved deck frame can also be used where a straight deck rail would not fit. Whether you want to build a curved deck frame around a hot tub, or just want to add a unique touch to your deck, you can build one using common tools and materials.

When building a curved deck frame, it is important to use the right lumber. The lumber needs to be strong enough so it will not sag under the weight of the people who will be using it. It also needs to be able to withstand weather conditions such as rain or snow without rotting or warping. The best choice for this type of project is cedar lumber because it has natural resistance against rot and deterioration from moisture. Cedar does not need any type of finish because it has an attractive reddish brown color that does not need to be stained or painted.

The first step in building a curved deck frame is measuring the length and width of your desired shape with string and then marking these measurements on your lumber with chalk lines so you can cut them out with power saws or circular saws. Next use two-by-four plan

Building a curved deck is not that different than building a straight one. You just need to be more careful about your measurements and design. Here are some tips for building your curved deck:

1. Make sure you have enough room for the radius you want. A deck with a radius of 6 feet can be built in an area as small as 20 feet by 10 feet, but if you want a larger radius, you may need to consider moving back from the house or adding more space behind the house.

2. Measure the distance between the center post and end posts at each section of the curve before cutting them down to size. This will ensure that when they’re all connected together they make up the correct shape and size.

3. Use flexible polyethylene pipe as a form around which concrete can be poured for support posts or footings. The pipe is cheap, easy to use and allows you to pour concrete around it without having to worry about it falling over or getting damaged during construction. When finished pouring, simply remove it from the hole using pliers or tongs and proceed with other steps in your project plan

A curved deck is a beautiful sight to behold. It can add to the overall aesthetic of your home and give you a unique space for entertaining or relaxing. A curved deck is also an economical way to increase the size of your deck without having to build any additional structure.

The first step in building a curved deck is determining whether it’s structurally possible. If you already have a deck, simply measure the distance between the posts. If this distance is less than 12 feet, you can use pressure-treated lumber for framing. For longer distances, you will need to use cedar or redwood because they are more resistant to moisture damage than pressure treated wood.

Once you’ve determined which type of lumber to use, cut out all of your pieces using a circular saw. Make sure that each piece is exactly 45 degrees with respect to its neighbor on either side. This can be done by using a protractor or simply placing two sticks together at an angle and marking where each piece should be cut on both sides so that they meet in the middle when put together properly (see pictures).
