Quick Answer: In a stacked townhome, end units are typically 100-200 sq ft larger than interior units and have side windows that change bedroom layout options. Interior units share both side walls, making them warmer and quieter. Both unit types usually fit a Double or Queen mattress in the master bedroom, but end units often allow more flexible furniture placement.

What Is a Stacked Townhome, and Why Does It Matter?
A stacked townhome is two separate homes built vertically on the same footprint. The lower unit occupies the ground and main floor. The upper unit sits above it, typically accessed by a private interior staircase or an exterior side entrance. Neither unit has a backyard, and both share at least one horizontal floor-ceiling assembly with the other unit.
In Brantford, stacked townhomes have become common across both new market-rate developments and affordable housing communities. JC Homes, Brantford's Jaycee non-profit housing provider operating since 1983, manages 84 scattered properties across the city, a number of which are stacked townhome-style units. For families and individuals moving into these homes, understanding the difference between interior and end unit configurations is practical information that affects everything from heating bills to which mattress actually fits through the door.
Interior vs End Unit: The Real Differences
This is where most buyers and renters get a bit of a surprise when they first walk through both units back to back.
Shared Walls and Thermal Comfort
An interior stacked townhome unit shares both side walls with neighbouring units. Those shared party walls act as thermal buffers. In a Brantford winter, when temperatures regularly fall below -10 C, interior units stay warmer with less energy because the neighbouring units on both sides block heat loss. One non-scientific study comparing two identical condos of similar age and construction found the end unit cost approximately 40% more to heat than the interior unit. The geometry is simple: more exterior wall exposure means more heat loss, and end units have significantly more of it.
What End Units Gain
End units have one exposed side wall instead of two, which means:
- Side windows on the exposed wall, bringing in cross-ventilation and natural light from a second direction
- No neighbour noise on the exposed side
- A sense of more space, even if the square footage difference is modest
- Sometimes a slightly larger footprint, typically 100-200 sq ft more than the interior version of the same model
That extra square footage is not always evenly distributed. Builders sometimes use the end unit advantage to add a small side utility closet, widen a hallway, or expand the living room rather than the bedrooms. Always measure the actual bedroom before assuming the end unit automatically gives you a larger sleeping space.
What Interior Units Gain
Interior units tend to be quieter on the side walls because neighbours absorb street noise before it reaches you. Utility costs are lower. And at the price level typical of Brantford affordable housing and new entry-level market builds, interior units are often $10,000-$20,000 less than end units of the same model. Brad at our West Street showroom points out that many couples who come in to buy a mattress for a new Brantford townhome do not realize they can sometimes put that saving toward a better mattress, which has a direct effect on daily sleep quality.
JC Homes and Stacked Housing in Brantford
JC Homes (Jaycee Homes) has provided scattered affordable housing units across Brantford since 1983. Their portfolio includes converted properties and purpose-built stacked townhome units. Residents moving into a JC Homes stacked property often inherit older bedroom configurations, sometimes with non-standard wall placements or load-bearing interior walls that limit furniture rearrangement. If you are moving into one of these units, measure the bedroom before your mattress is delivered. Call us at (519) 770-0001 and we can help you work through the dimensions over the phone.
Bedroom Size and Layout: Interior vs End Unit
Here is where the real decision point lives for anyone buying a mattress before or shortly after moving in.
Interior Unit Bedroom Dimensions
Ontario Building Code requires a minimum bedroom area of 9.8 sq m (approximately 105 sq ft) for any bedroom beyond the first in a dwelling unit. A typical master bedroom in a Brantford affordable stacked townhome interior unit runs between 10x10 ft and 11x12 ft, depending on the building age and layout style.
In a 10x10 ft bedroom, a Queen mattress (60x80 inches) works but leaves modest clearance on three sides. A Double (54x75 inches) is more comfortable if you want space for a small dresser or nightstands without bumping into the bed. A King mattress (76x80 inches) is not practical in a 10x10 room regardless of unit type.
In an 11x12 ft master bedroom, a Queen fits well and a Queen with a double-sided nightstand configuration is achievable. A King is possible only if the closet is positioned on the short wall and the room is otherwise clear.
Interior Unit Bedroom Quick Reference
- 10x10 ft bedroom: Double recommended, Queen possible with tight clearances
- 10x11 ft bedroom: Queen comfortable with nightstands if closet is on short wall
- 11x12 ft bedroom: Queen ideal, King only if wardrobe placement cooperates
- Second bedroom (typical 9x10 ft): Twin or Double only
End Unit Bedroom Dimensions
End units of the same model are typically 100-200 sq ft larger overall. That extra space does not always land in the bedroom, but when it does, the master bedroom may run 11x13 ft or 12x12 ft. This is a meaningful difference. A 12x12 ft master bedroom can accommodate a King mattress (76x80 inches) with approximately 24 inches of clearance on each side wall, which is the minimum recommended for comfortable bed-making and nightstand access.
The side window in an end unit also matters for furniture placement. An interior unit bedroom typically has windows only on the exterior front or rear wall. An end unit bedroom may have a window on the exposed side wall, which limits where a headboard can go. You generally do not want to place a bed under a window if you can avoid it in Ontario's climate, since drafts from single-pane or older windows can disrupt sleep, especially between October and March.
The Side Window Problem
If your end unit bedroom has a side window, position the bed on the wall opposite the side window, with the headboard against the interior party wall. This gives you the natural light and cross-ventilation benefits of the window without the draft disrupting sleep. In Brantford winters, even a well-sealed newer window creates a cold zone within about 18 inches of the glass.

Mattress Guide by Unit Type
The unit type does not change which mattress feels comfortable. It changes which mattress physically fits and works with your room layout.
For Interior Units (Compact Bedrooms)
Our Restonic ComfortCare Double (980 individually wrapped coils) is the most common mattress we sell to Brantford customers moving into compact stacked townhome units. At $995, it gives solid motion isolation, good pressure relief on the shoulder and hip, and leaves enough room on each side of the bed to function without feeling cramped.
If two adults are sharing the bedroom and the room is at least 10x11 ft, the Restonic ComfortCare Queen at $1,619 with 1,222 individually wrapped coils is worth the upgrade. The coil-in-coil construction provides better motion separation than a typical all-foam mattress, which matters when one partner gets up at different times.
For End Units (Slightly Larger Bedrooms)
End unit master bedrooms in the 11x13 ft range open up the option for a Queen without compromise, or a King if the room is 12x12 or larger. Our Restonic ComfortCare King has 1,440 individually wrapped coils at $2,051. For a 12x12 room, it fits but leaves exactly 24 inches of walkway on each side, which is functional if not generous.
Dorothy, our sleep specialist, recommends that anyone considering a King in a stacked townhome end unit do a paper tape test first: lay down tape on your current or future floor in the exact dimensions of the King footprint (76 inches wide, 80 inches long) and walk around it for a week. If it feels too tight, a Queen is the better long-term choice.
End Unit Bedroom Quick Reference
- 11x11 ft bedroom: Queen recommended, King not advised
- 11x13 ft bedroom: Queen or King both fit, depending on furniture arrangement
- 12x12 ft bedroom: King fits with 24-inch side clearances if closet is on short wall
- Second bedroom (typical 9x11 ft): Double or Twin
Mattress Delivery Through Stacked Townhome Staircases
Stacked townhomes are accessed by staircases, not elevators. This is the practical constraint that overrides everything else when deciding on mattress size.
Our white glove delivery team has brought mattresses into dozens of Brantford stacked townhomes. The staircase geometry is almost always the binding constraint: a steep 42-degree staircase with a 36-inch width is manageable for a Queen. A 180-degree landing turn with low headroom is where King mattresses sometimes stop being deliverable.
Before ordering, measure your staircase:
- Staircase width at the narrowest point (including handrail)
- Headroom clearance at the top landing
- Whether the staircase makes a turn and if so the turning radius
A Queen mattress (60x80 inches) typically navigates staircases with 36-inch widths and standard Ontario-code headroom. A King mattress (76x80 inches) requires careful assessment. Call Brad at (519) 770-0001 with your staircase measurements before purchase, and we can advise before you commit.

Is an end unit stacked townhome always worth the extra cost?
Not always. End units cost more to buy or rent and typically 30-40% more to heat in winter, which adds up significantly in a Brantford climate. The extra square footage and side windows are genuine benefits, but if the bedroom dimensions are similar to the interior unit (which is sometimes the case), the lifestyle gain may not match the financial premium. Look at actual bedroom measurements, not just total square footage.
Can I fit a King mattress in a Brantford stacked townhome?
Possibly in an end unit with a bedroom measuring at least 12x12 ft, provided the staircase has adequate width and landing clearance. In interior units with bedrooms in the 10x10 to 11x12 ft range, a King is generally not practical. We always recommend measuring your bedroom and staircase before purchasing a King-size mattress in any stacked townhome.
Do side windows in end units affect sleep quality?
They can, in two ways. More morning light is generally positive for circadian rhythm regulation, but if the window faces an active street or parking area, light pollution and noise can disrupt sleep onset. Ontario winters also create cold drafts near windows, even in newer construction. Avoid placing your bed within 18 inches of a side window, and use blackout curtains if needed.
What mattress does Mattress Miracle recommend most often for stacked townhomes?
The Restonic ComfortCare Queen ($2,395 / 1,222 individually wrapped coils) is our most recommended mattress for Brantford stacked townhome bedrooms in the 10x11 ft to 11x13 ft range. It fits without crowding the room, provides solid motion isolation for couples, and is firm enough for lower back support without being uncomfortably hard. For smaller 10x10 ft bedrooms, the Restonic ComfortCare Double at $995 is the better call.
Does JC Homes allow mattress white glove delivery with staircase access?
Delivery policies vary by property, but most JC Homes stacked units permit standard furniture delivery during reasonable hours. Our white glove team handles shoe covers, floor protection, and careful staircase navigation as standard. Call us before your move to confirm the staircase dimensions and we will advise on the best mattress size and delivery approach for your specific unit.
