How to Plan a Mudroom Bump Out Addition to Your House

Jan 27, 2022 | Additions & Interiors

Mudrooms have come a long way from being the purely functional spaces they once were. Traditionally, they were a place where you were expected to store your muddy and dirty belongings from the outside to protect the rest of your home. Therefore, it’s no wonder they were lacking in glamour. But in recent times, these vital areas have been given a style update, where homeowners are looking at both the aesthetics and functionality of mudrooms when they start a home improvement project. After all, although smaller than many other areas in your home, they can give you extra space that can double up as a nifty multipurpose area for storage or even as a laundry room.

To create your mudroom, instead of carving out space in your existing entryway, it could work well to create a separate micro addition or a bump-out addition. This adds extra square footage to your home, which is always an advantage even if the amount it adds isn’t as much if you were to opt for a full-sized addition.

Follow These Key Steps

As far as home additions are concerned, many factors need to be looked at apart from just the cost of bumping when it comes to creating a mudroom. To start with, you need to focus on the right location. If you often enter through the front door, it would work well to create your mudroom bump out in front of your living room.

However, if the kitchen side of your house is the more common everyday entry point for your family, a kitchen bump-out might be more practical and can allow for a seamless transition to this room. Both options should be designed in a way that makes them discreet, unobtrusive, and well-integrated. Your mudroom should be constructed in a way that keeps your existing building codes in mind. When done right, it can create both a visual and thermal buffer for your home.

After deciding your location, look at the area earmarked for your mudroom. For instance, are you looking at adding a cantilevered bump-out, which extends horizontally? This type of bump-out has no support below, so the depth of the bump-out is restricted to just two or three square feet. Since it cannot extend too far out from the house, the size of the joists becomes a key consideration here. A general rule of thumb is that bump-outs can be cantilevered at a distance equal to four times the size or depth of the floor joists. This means that for every foot you cantilever outward, the cantilevered joists should extend twice that length along an existing joist. To put it in perspective, if your bump-out cantilevers 3 feet, you need to have a minimum of 6 feet running alongside an existing joist inside the house.

Your next step is to look at your house structure, take note of how the house will open into this mudroom, and plan accordingly. You need to have proper permits for everything, from electrical sanctions to the plumbing or the construction work. Your foundation work needs to be solid and should include all aspects, such as installing temporary wall support and building a strong foundation wall. Also, take into account the rewiring and rerouting of electric wires you need to do. For safety, once the electric circuits are shut down, and the studs are left exposed with no drywall, use plywood sheets as a temporary measure to cover them up. See that walls, subfloor, doors, windows, window seats, and ceilings are all built to a specific height, keeping both your original structure and new addition in mind. It is possible to install a lean-to-style or shed roof in many mudroom bump-outs that start higher than the opening of the house and then slope downward. Finally, look at your finishing touches, like picking the right kind of flooring to complete your mudroom bump out.
