Can You Change the Layout of Your Home? A Remodeling Feasibility Guide for Orange County Homeowners

home remodeling change layout in Orange County project

If you’re planning a major remodel, one of the first questions is usually not what cabinets, tile, or flooring to choose.

It’s “Can we actually change this?”

Can we remove the wall between the kitchen and living room? Can we move the kitchen to the other side of the house? Can we make the primary bathroom larger? Can we move the toilet? Can we turn two smaller rooms into one larger space?

In many homes, the answer is yes, but how practical and expensive the change will be depends on what’s behind the walls, under the floor, and above the ceiling.

We work on kitchen remodels, bathroom remodels, and full home renovations throughout Orange County, and layout changes are often where the project starts becoming more involved. Structure, plumbing, electrical, HVAC, foundation conditions, engineering, and permitting can all affect what makes sense.

What Should You Know Before Changing Your Home’s Layout?

Here’s what homeowners should understand before committing to a new floor plan.

Can You Change the Layout of an Existing Home?

Yes. An existing home does not have to keep its original floor plan.

Depending on the house, a remodel can involve:

But there’s an important difference between “Can it be done?” and “Does it make sense to do it?”

Almost anything can become possible with enough structural work, engineering, utility relocation, and budget. The better question is whether the proposed layout can be achieved in a practical way for your particular home.

That’s what should be determined before the design gets too far.

What Determines Whether a Layout Change Is Possible?

When we look at a home for a major remodel, we’re not only looking at the rooms you can see.

We also need to understand how the house is built.

A proposed layout may be affected by:

This is why we recommend evaluating feasibility before finalizing the new floor plan.

Can You Remove a Wall to Create an Open Floor Plan?

Usually, but the first thing we need to determine is whether the wall is load-bearing or non-load-bearing.

So when someone tells us, “We just want to take this wall out,” our next question is what that wall is actually doing.

Can a Load-Bearing Wall Be Removed?

Yes. Load-bearing wall removal is common in larger kitchen and whole-home remodels, particularly when homeowners want an open-concept kitchen, dining, and living area.

But you cannot simply demolish the wall.

A structural engineer may need to determine how the existing house is supported and design a replacement structural system.

Depending on the home, that could include:

The beam itself may sometimes be concealed within the ceiling. In other situations, part of the beam or posts may remain visible.

That’s something worth determining early because it can affect both the design and the budget.

How Do You Know if a Wall Is Load-Bearing?

Sometimes there are clues based on the wall location and the direction of the framing, but homeowners should not rely on visual assumptions alone.

A wall that looks insignificant may be carrying structural loads. Another wall that runs through the middle of the home may not be carrying what you expect.

Plans can help if accurate original drawings are available, but existing conditions may still need to be verified.

For a significant wall removal, we recommend confirming the structural conditions before building the remodel around the assumption that the wall can simply disappear.

Can You Relocate a Kitchen?

Yes, a kitchen can be relocated, but moving a kitchen is considerably different from remodeling one in its existing location.

Suppose your current kitchen is at the back of the house, but you want to move it into an underused dining or living area.

Now we need to determine how we’ll get everything the new kitchen requires to that location.

That can include:

The new kitchen may also require wall removal, new openings, flooring changes, or structural modifications.

This doesn’t mean relocating a kitchen is a bad idea. Sometimes moving the kitchen is exactly what allows the entire house to work better.

But it needs to be evaluated as part of the overall remodel rather than treated as simply moving cabinets from one room to another.

Can You Expand a Kitchen Into Another Room?

Absolutely, and this is often one of the more practical ways to improve an older floor plan.

For example, a kitchen might be expanded into:

Instead of relocating the entire kitchen, we may be able to remove or reposition a wall and extend the existing kitchen footprint.

This can create room for a larger island, more cabinetry, additional pantry storage, better appliance placement, or improved circulation between the kitchen and living areas.

The main question again is what separates the two spaces. If it’s a load-bearing wall, the structural work needs to become part of the design.

 

Can You Move a Kitchen Island or Add a Larger Island?

Usually, yes.

But before deciding on the largest island that will fit on a drawing, we look at how people will actually move around it.

A kitchen island needs appropriate clearance around cabinets, appliances, seating, and major traffic paths.

Utilities matter too.

An island with only storage and seating is relatively straightforward. An island containing a sink, dishwasher, cooktop, or other equipment may require plumbing, electrical, ventilation, or gas work.

Flooring can also become an issue when an existing island is removed or relocated, especially if the finished flooring does not continue underneath it.

The goal isn’t simply to fit a large island into the room. It’s to make sure the island improves how the kitchen works.

Can You Expand an Existing Bathroom?

Yes. Bathroom expansion is something we frequently evaluate during larger remodels.

Sometimes a primary bathroom feels small even though there is usable space immediately beside it.

Depending on the floor plan, we may be able to borrow space from:

That extra room could allow for a larger walk-in shower, double vanity, freestanding tub, private toilet area, or improved storage.

Before moving walls, however, we need to look at structure and plumbing, particularly where the toilet, shower, and main drain lines are located.

 

Can You Relocate a Bathroom?

Yes, but relocating an entire bathroom is generally more involved than expanding one near its existing location.

The biggest consideration is usually plumbing.

A new bathroom location needs suitable routes for water, waste, and vent lines. The feasibility can depend heavily on the home’s construction.

For example, relocating bathroom plumbing in a raised-floor home can present different options than doing the same work in a house built on a concrete slab.

Electrical, exhaust ventilation, waterproofing, structural framing, and code requirements also need to be considered.

This is one of those situations where seeing the house makes a significant difference.

 

Can You Move a Toilet During a Bathroom Remodel?

Yes, a toilet can be moved, but it is one of the plumbing fixtures we pay particularly close attention to when changing a bathroom layout.

A toilet requires a relatively large waste connection with proper slope and venting.

Moving it a short distance may be practical. Moving it to the opposite side of the bathroom—or into a completely different part of the house—can require considerably more plumbing work.

On a slab foundation, that may involve opening the concrete to install or reroute the drain.

That doesn’t automatically mean you shouldn’t move the toilet.

If relocating it creates a dramatically better bathroom layout, the additional work may be worthwhile. We simply want homeowners to understand what the layout change involves before committing to it.

 

Can You Move a Shower or Bathtub?

Yes.

Showers and bathtubs can generally be relocated as part of a full bathroom remodel, provided the new location can accommodate the necessary plumbing and drainage.

For example, we might replace an older tub-and-shower configuration with a larger walk-in shower, relocate the tub, or completely rearrange the wet area of a primary bathroom.

This is also the point where waterproofing, drain placement, shower slope, valves, ventilation, electrical requirements, and framing all need to work together.

A bathroom layout should therefore be designed around more than appearance.

Can Plumbing Fixtures Be Relocated During a Remodel?

Yes. Sinks, faucets, showers, tubs, toilets, dishwashers, refrigerators, washing machines, and other plumbing fixtures can often be relocated.

The question is how far they need to move and what is required to reach the new location.

We consider:

Keeping fixtures near their existing plumbing locations can sometimes reduce complexity and cost.

But we don’t recommend keeping a poor layout solely because “the plumbing is already there.”

For a substantial remodel, it makes sense to compare both options: what it costs to keep the existing configuration versus what you gain by changing it.

 

Can You Add Another Bathroom to an Existing Home?

In many cases, yes.

Adding a bathroom is particularly common during a full home remodel when homeowners want another guest bathroom, an ensuite bathroom, or a more functional primary suite.

The first question is where it should go.

A new bathroom near existing plumbing may be more straightforward, but proximity isn’t the only consideration. We also need enough space for the fixtures, proper ventilation, electrical requirements, privacy, circulation, and a workable plumbing route.

Depending on the layout, a new bathroom may be created from part of a bedroom, closet, laundry area, hallway, or another portion of the house.

If the bathroom requires expanding the home’s footprint, the project becomes an addition and brings additional zoning, structural, and permitting considerations.

 

Can You Add or Relocate a Laundry Room?

Yes.

Laundry rooms can often be relocated or added as part of a larger renovation.

We may need to provide or relocate:

A laundry relocation can make a major difference in how a home functions, especially when an older house has the washer and dryer in the garage or another inconvenient location.

 

Can You Raise or Vault a Ceiling?

Sometimes.

This is one of the changes that requires us to understand the roof structure before promising anything.

A flat ceiling may conceal:

Some roof structures can be modified to create a vaulted ceiling. Others require substantial engineering and reconstruction.

If you’re considering a vaulted ceiling as part of an open-concept remodel, we recommend investigating the roof framing early instead of designing the entire space around a ceiling that may be impractical to build.

 

Can You Make a Window or Exterior Door Larger?

Usually, but changing an opening in an exterior wall can become structural work.

A wider window, larger patio door, or new opening may require a new header and changes to the surrounding framing.

The situation becomes more involved when homeowners want very wide sliding or folding doors connecting the interior to the backyard.

Those openings can dramatically improve indoor-outdoor living, but the wall above still needs proper structural support.

The location of electrical, plumbing, HVAC, exterior finishes, and shear walls may also affect what can be done.

 

Can You Add or Relocate Windows?

In many cases, yes.

We often look at window placement when reworking kitchens and bathrooms because the original window location may conflict with the new layout.

For example, a kitchen redesign may benefit from a wider window over the sink, while a bathroom remodel may need a different window location to accommodate a larger shower or vanity.

Exterior modifications can introduce additional planning, structural, energy-code, waterproofing, and sometimes HOA considerations, so window changes should be incorporated into the plans early.

 

Can You Turn Separate Rooms Into an Open-Concept Layout?

Yes, and this is one of the most common goals we see in larger Orange County remodels.

Older floor plans often separate the kitchen, dining room, and living areas with multiple walls and narrow openings.

Instead of looking at each room separately, we look at how the entire main living area could function.

Sometimes that means removing one wall.

Other times, the better solution is a combination of:

The best open-concept remodel isn’t necessarily the one with the fewest walls. It’s the one where the kitchen, dining, living, storage, and circulation actually work together.

 

Can You Change a Staircase During a Remodel?

Potentially.

A staircase takes up much more of a floor plan than homeowners sometimes realize, so relocating or redesigning it can dramatically change both floors of a house.

It can also be a significant structural project.

We need to consider floor framing, headroom, rise and run, landings, guardrails, structural openings, and how the staircase connects the two levels.

For a full home remodel, however, it can be worth evaluating if the existing staircase is preventing the rest of the floor plan from working properly.

 

When Does a Remodel Require a Structural Engineer?

A structural engineer may be needed when the remodel changes how the house is supported.

Common examples include:

The engineer’s role isn’t simply to “approve” wall removal.

They determine how the loads will be transferred after the existing structural components are changed and provide the calculations and details needed to build the new condition safely.

For projects involving structural changes, engineering should be coordinated with the architectural layout—not treated as an afterthought once construction begins.

 

Do You Need a Permit to Change the Layout of a House in Orange County?

For significant layout changes, you should generally expect permits to be part of the project.

Structural changes such as removing or relocating walls typically require plans and review. Plumbing, electrical, mechanical, window, door, and other modifications may also trigger permit requirements.

Requirements can vary depending on the city and scope of work.

For example, official kitchen-remodel guidance from the City of Laguna Hills distinguishes simpler non-structural renovations from projects involving wall removal, structural changes, or relocated plumbing and requires additional plans or review for those conditions.

That’s why we don’t recommend assuming a remodel is “interior only” and therefore doesn’t need permits.

If you’re removing walls, relocating kitchens or bathrooms, moving significant plumbing, changing structural openings, or substantially altering the floor plan, permit requirements should be investigated during planning.

What Makes Changing a Home’s Layout More Expensive?

The biggest cost increases usually come from what has to change behind the finished surfaces.

A layout change becomes more involved when it requires:

This is why comparing remodel estimates solely by square footage can be misleading.

Two kitchens of exactly the same size can have very different construction costs if one keeps the existing layout and the other relocates plumbing and removes a load-bearing wall.

 

Should You Keep the Existing Layout to Save Money?

If you already like the layout, keeping major plumbing and structural components where they are can absolutely help control costs.

But we wouldn’t automatically design around the existing layout simply because it’s cheaper.

If you’re investing in a substantial kitchen, bathroom, or whole-home remodel, it’s worth asking:

Does the existing layout actually work for the way you live?

Before replacing everything in exactly the same locations, this is the time to determine whether a better floor plan is possible.

Sometimes keeping the layout makes perfect sense.

Sometimes changing it is what makes the entire remodel worthwhile.

 

How Do You Know What’s Possible Before Starting a Remodel?

This is where we recommend starting, not with demolition and not with finish selections.

Start with the house itself.

For a remodel involving significant layout changes, we want to understand:

That’s one of the advantages of working with a design-build team. Design decisions are being evaluated alongside the realities of construction instead of designing a floor plan first and figuring out whether it can actually be built later.

Frequently Asked Questions

Can you completely change the floor plan of a house?
Yes. Depending on the existing structure and budget, a whole-home remodel can substantially change the original floor plan. Walls can be removed or relocated, kitchens and bathrooms can be reconfigured, rooms can be combined, and openings can be changed. Structural, plumbing, electrical, HVAC, and permitting requirements determine how involved those changes will be.

Can you remove a load-bearing wall?
Yes, in many cases. A load-bearing wall can often be replaced with an engineered beam and appropriate supports. Structural engineering, plans, permits, and sometimes foundation work may be required.

Do I need a structural engineer to remove a wall?
If the wall is load-bearing or the proposed change affects the home’s structural system, structural engineering may be required. The need depends on the existing framing and proposed modification.

Is it expensive to move plumbing during a remodel?
It can be. Cost depends on what is being moved, how far it needs to move, the location of existing drain and vent lines, and whether the home has a slab or raised foundation. Moving a toilet or entire kitchen generally has more impact than shifting a sink a short distance.

Can you move a toilet to the other side of a bathroom?
Often, yes. The new location needs a workable drain, vent, and water connection. On slab foundations, moving the toilet may require cutting and repairing concrete.

Can you move a kitchen to another room?
Yes. A kitchen can be relocated if water, drainage, electrical, ventilation, and any required gas service can be provided at the new location. Structural and permitting considerations may also apply.

Can you make a small bathroom bigger?
Often, yes. Bathrooms can sometimes expand into an adjacent closet, bedroom, hallway, or other space. The best option depends on the surrounding floor plan and plumbing.

Do you need a permit to remove a non-load-bearing wall?
Possibly. Even if the wall itself isn’t structural, it may contain electrical wiring, plumbing, HVAC, or other systems, and local permit requirements vary. The proposed scope should be reviewed before demolition.

Can you remodel a house without changing the layout?
Absolutely. If the existing floor plan already works well, keeping plumbing and structural elements in place can simplify the project and allow more of the budget to go toward cabinetry, fixtures, materials, and finishes.

Should I change the layout during a full home remodel?
If there are problems with circulation, room sizes, storage, kitchen placement, bathroom configuration, natural light, or indoor-outdoor access, a full home remodel is usually the best time to evaluate those issues. Once new flooring, cabinetry, drywall, and finishes are installed, changing the layout later becomes much more disruptive.
