Not every open-concept goal requires full load bearing wall removal. A partial opening, an archway, a pass-through, a header beam over a doorway-sized gap, can achieve a similar effect for less cost and disruption. This is a genuine decision point worth thinking through, not just a question of "go big or don't bother."
What Full Load Bearing Wall Removal Involves
The entire wall comes out, replaced by a full-span beam and supporting posts sized to carry the complete load that wall was holding. This is the most disruptive and most expensive of the two options, but it maximizes the open floor plan, typically connecting an entire kitchen fully to an adjacent living space with no visual break at all.
What Partial Wall Removal Involves
Only a section of the wall is opened, an archway, a pass-through window, or a partial beam installed over a doorway-sized opening, while the remaining wall sections stay in place and continue carrying their share of the load. This generally involves simpler engineering than a full-span removal, since less load needs to be transferred to a new beam. Not sure whether your wall is structural? See how to tell if a wall is load bearing.
Cost Comparison
Full removal typically costs more due to the larger beam sizing required for a full-span load transfer, plus more extensive finishing work once the wall is entirely gone. Partial removal can run a fraction of that cost, depending on the size of the opening, since the header beam and supporting engineering scope are both smaller.
Structural Complexity Comparison
Full removal usually requires a larger, more expensive beam, and sometimes additional support posts or new footings to handle the complete load. Partial openings can often use a shorter header beam with simpler support requirements, since the remaining wall sections on either side continue to share the structural load.
| Factor | Full Removal | Partial Removal |
|---|---|---|
| Visual Effect | Fully open floor plan, no visual break | Improved flow with some visual separation retained |
| Engineering Scope | Larger, full-span load calculation | Smaller, localized header beam calculation |
| Typical Cost | Higher | Lower |
| Disruption | More extensive demolition and finishing | More contained scope of work |
Which One Fits Your Goal
Choose Full Removal If...
You want a true open-concept great room, with the kitchen fully open to the living space and no remaining visual division between the two areas. See how open concept renovations combine wall removal with underpinning.
Choose Partial Removal If...
You want more light and better flow between rooms without losing the sense of separation entirely, or if budget is a bigger constraint on this particular renovation.
Can You Upgrade From Partial to Full Later?
Generally yes, with proper planning, though it means a second phase of engineering and construction down the line rather than a simple extension of the original work. If there's a real chance you'll want to go further later, it's worth mentioning that to your engineer upfront, since it can influence how the initial partial opening is framed.
A useful way to decide: if you're on the fence, partial removal is the lower-risk, lower-cost way to test whether an open-concept layout actually suits how you live, before committing to the larger full-removal project.
The Common Types of Partial Opening
"Partial" covers a range of designs, and knowing the options helps you describe what you want to a contractor and an engineer. Each of these still involves a structural header and a permit, but they produce quite different results.
- A wide cased opening. The wall is opened across a generous width, framed with trim, and left with narrow wall sections at each side. It is the most common choice, since it improves flow and light while keeping the rooms distinct.
- An archway. A softer look in the same position, usually built as a decorative finish beneath a straight structural header. The engineering is the same as for any other opening of that width.
- A pass-through. A window-like opening between kitchen and dining room, often with a counter. It brings light and conversation without removing the wall below.
- A widened doorway. Making an existing doorway larger, which is the smallest and simplest option.
- A half wall. The wall is reduced to counter height with the upper portion opened, which is typically not structural at all once the load is carried above.
Because the load above still has to be carried, the width and position of the opening matter. A wider opening needs a larger header, and an opening near a corner or an intersecting wall can change how the load travels, which is why the engineer assesses each one individually.
How the Remaining Wall Shares the Load
The main structural difference between full and partial removal is where the weight goes. With a full removal, the whole load is picked up by one beam and carried to posts at each end. With a partial opening, the wall that remains continues to carry part of the load, and the header carries the rest across the new gap.
That has two consequences worth understanding. The first is that the sections of wall left standing on each side of the opening, often called piers or jambs, may now carry more load than they did before, because they also support the ends of the header. They have to be strong enough, and the footings or supports under them have to be able to take that concentrated load. The second is that you cannot treat the remaining wall as untouchable. If it is later altered, for example by adding a door or a window, the structural picture changes again.
This is why even a modest-looking opening needs engineering, and why the stamped drawings should show not just the header but the support at each end. The same documentation matters at resale, which is why we recommend reading our load bearing wall removal permit guide.
Four Questions to Decide Between Them
If you are torn, working through a few honest questions usually reveals the answer.
- How do you actually use the two rooms? If you cook while entertaining and want to see the whole space, full removal serves you. If you prefer to keep cooking mess and noise separate, a partial opening may suit you better.
- How much light and sightline do you need? A dark, enclosed kitchen may be transformed by a wide opening alone.
- What is your budget and tolerance for disruption? A partial opening costs less and takes less time to finish.
- Do you need the wall for storage or services? Cabinets, outlets, ductwork and plumbing in the wall are easier to keep with a partial opening.
It also helps to see the numbers. Our load bearing wall removal cost guide shows what each scope tends to cost, and our load bearing wall removal page explains how a free assessment works. If the answers are not clear, a partial opening is the lower-risk way to find out.
Staging the Project Over Time
One advantage of a partial opening is that it does not close any doors. If you live with it for a year and decide you want more, you can go further, although the second step is a new structural project with its own engineering and permit.
Because of that, it is worth telling your engineer at the start if you might expand later. The first opening can sometimes be framed in a way that makes the second phase simpler, for instance by placing the supports where they will still be useful, or by leaving flooring and finishes that can be matched. Equally, design the first phase so it looks complete on its own. A partial opening that feels like an unfinished compromise is harder to enjoy than one that was designed to be the final answer.
If you do come back for a second phase, expect the same steps again: assessment, stamped drawings, a permit and inspections. Budgeting for that possibility, even if you never use it, keeps the decision honest. Our load bearing wall removal timeline guide shows how long each phase takes.
Frequently Asked Questions
Yes. Any change to a load bearing wall, full or partial, involves structural work and requires engineering and a City of Toronto permit. The scope of the engineering may be smaller for a partial opening, but the process itself follows the same permitted path.
Yes. Even a smaller partial opening changes how load moves through the wall, so a structural engineer still needs to calculate the header beam size and confirm the remaining wall sections can properly carry their share of the load.
Sometimes, but not automatically. Widening a partial opening later is a new structural change requiring its own engineering and permit, and depending on how the original opening was framed, it may or may not be straightforward to expand. Planning for a possible future expansion upfront is worth discussing with your engineer.
It depends on the buyer expectations in your specific neighbourhood and price range. A full open-concept conversion tends to have broader appeal in markets where that's the dominant expectation, while a well-executed partial opening can still meaningfully improve flow and light for a lower cost, appealing to buyers who value some room definition.
Yes. While the section of wall is removed and the header installed, the load above has to be carried temporarily, just as in a full removal. The shoring is smaller in scale for a small opening, but it is still part of the plan and still stays until the permanent header is secure and approved.
Yes, as a finish. An archway is generally built beneath a straight structural header, so the engineering is the same as for a rectangular opening of that width. The curve is created with framing and drywall afterwards, and it does not change what the header has to carry.
