How to Building a Room Addition on Piers

Building an addition on piers is a great way to add extra living space to your home. The first step is to determine the size and location of the addition. Once you have the dimensions, you will need to excavate the area for the footings.

Next, you will need to pour concrete footings and install pier blocks. After the pier blocks are in place, you will need to install framing and sheathing. Finally, you will finish the exterior of the addition and add any interior finishes.

  • Clear the area where the room addition will go and excavate for piers
  • Pour concrete footings for the piers and allow them to cure
  • Construct framing for the floor of the room addition
  • Install pier brackets on the frame and attach them to the piers
  • 5 Suspend floor joists from the pier brackets and install plywood or OSB subflooring
  • 6 Finish installing walls and ceiling framing as well as any exterior sheathing

Pier And Beam Room Addition Cost

Adding a room to your home is a big decision. Not only do you have to decide what type of room you want to add, but you also have to think about the cost. If you’re considering a pier and beam room addition, you’re probably wondering how much it’s going to cost.

The short answer is that it depends on a variety of factors, including the size of the room, the materials used, and whether or not you hire a contractor. However, we can give you a ballpark estimate based on the average cost of materials and labor. For a small pier and beam room addition (10×10), you can expect to pay around $5,000-$7,000.

For a medium-sized addition (20×20), the cost will be closer to $10,000-$15,000. And for a large addition (30×30), the price tag will be more like $20,000-$30,000. Of course, these are just estimates – actual costs will vary depending on your specific project.

Is It Cheaper to Build on a Slab Or Piers?

In most cases, it is cheaper to build on a slab. The main reason for this is that piers require more materials and labor to construct. Additionally, piers can add significantly to the cost of a foundation if they are not built properly.

Is It Cheaper to Build a House on Piers?

Building a house on piers can be cheaper than building a traditional foundation, but it depends on several factors. The most important factor is the soil type. If the soil is soft or unstable, piers will be more expensive because they must be driven deeper into the ground to reach stable soil.

The number of piers needed also affects cost. More piers mean higher material and labor costs. Finally, the height of the pier can also affect cost. Higher piers require more concrete and steel, which increases costs.

Can You Add an Addition Without a Foundation?

It’s not recommended to add an addition without a foundation. The foundation helps support the weight of the addition and prevents it from settling or shifting. Without a foundation, the addition may not be as stable and could suffer damage over time.


If you’re considering building a room addition on piers, there are a few things to keep in mind. First, make sure the area where you want to build is level. If it’s not, you’ll need to excavate and fill in until it is.

Next, mark out the perimeter of your addition with stakes and string so you know where to dig. Once you’ve dug the foundation, pour concrete footings and wait for them to cure before continuing. Then, build the frame of your addition using lumber or steel beams.

Finally, finish the exterior and interior of your new room however you like! With a little planning and effort, building a room addition on piers is definitely doable for most people.
