How To Plan A Bump-Out Addition

Do you think that your bathroom is a bit smaller and if there were more space, you could have added another fixture like a tub in there? Similarly, do you imagine your room being bigger than the current size and the things you could do with extra space? Many home addition contractors suggest a bump-out in this case.

Bump-Out Addition

With a bump-out addition, you can increase the square footage of a room, kitchen, or bathroom without going ahead with a full-scale addition.

The size of a bump-out depends on the needs of the homeowner. It can be a small bump out of a few feet or as big as a full room. It can be done for any room in your house although it’s commonly carried out for kitchens and bathrooms for adding more fixtures or features.

Steps For A Bump-Out Addition

Select The Area And Develop The Bump-Out Plans

Choose which room you want to bump out. You should keep it for only one room. Moreover, it’s better if the bump-out is on ground level because you will only need the walls and the roof for the bump-out. For a bump-out on another floor, you will also need to invest in additional support.

Afterward, go to an architect who can develop plans for your bump-out home remodeling project. Moreover, make sure that you involve a contractor from the first step of deciding the area so your decisions remain practical because the contractor will be there to let you know something you’re desiring is not possible.

Apart from that, a contractor can help you out in applying for permits as well. So, be sure to consult them.

Install A Temporary Support Wall And Create A Foundation Wall

One existing side of the wall will be removed. Therefore, for temporary support to the ceiling, walls, and floors, install a wall of studs close to the exterior wall.

Then, you should build a foundation wall for the bump-out addition. It’s necessary for a ground-level bump-out addition. Keep the depth as advised by the contractor, but you can go up to 42 inches deep.

If you want to keep the addition higher than the ground level or the addition is on an upper level, consider cantilever flooring. Get recommendations from your contractor so for correct measurements and materials.

Open The Exterior Wall And Install A Header

Before opening the exterior wall, make sure you have turned off electrical circuits and removed the sidings and drywall. Use a plywood sheet to cover the place when you have to end that day’s work.

After opening the wall, you should remove the electrical wires and plumbing system that was attached to the wall. Furthermore, take an LVL laminated wood header and install it where the wall was.

Walls, Subfloor, And Roof

Measure the height of the area and use stud walls that have windows of the measured height. Don’t stress out if the ceiling of the addition is lower than that of the house because it’s common due to the header’s width. When this is done, add joists and, later, subfloors that you can fit on top of the joists.

For the roof, most bump-out addition are small. Therefore, you can consider a lean-to roof. The roof will be higher from the house’s end and leans down as it goes from the house to the bump-out addition.

Siding And Drywall Along With Insulation Of The Addition

In this process, you will be adding siding. Later, you should insulate the walls by using spray foam or any other insulation material suggested by your contractor. After this step, you can add drywall. When the drywall is done, you can begin the painting process.

Finishing Touches

You have done all the important steps, but the finished touches are remaining. You can add tiles if this is a bathroom because tiles are the common floorings used for bathrooms. On the other end, if the bump-out is for a kitchen or a room, consider other types of flooring like laminate, hardwood, vinyl, and others.

Conclusion

A bump-out is a quicker and cost-effective way to increase some space in your house. The process is not DIY-friendly, so you should consider going to home addition companies DC to plan out and execute your bump-out addition.
