Matching a 1960s Split-Level Addition in Burnaby

Absolutely — a well-designed addition can blend seamlessly with a 1960s split-level, but it requires deliberate attention to rooflines, materials, proportions, and the distinctive multi-level geometry that defines the split-level form. Burnaby has thousands of split-levels built during the 1950s and 1960s housing boom, and experienced local designers understand how to extend these homes without creating an awkward mismatch.

The roofline is the single most important element for visual integration. Split-levels typically feature low-slope gable or hip roofs with moderate overhangs. The most common mistake in additions is introducing a roofline that doesn't match the pitch, overhang depth, or fascia profile of the original. Your designer should measure the existing roof pitch precisely (most 1960s Burnaby split-levels have pitches between 3:12 and 5:12) and replicate it on the addition. Where the new roof meets the old, a continuous ridge line or a cleanly integrated valley prevents the "tacked-on" appearance. If the addition sits below the existing roofline — as with a single-storey bump-out at the lower level of a split — tucking it under a shed roof that reads as a natural extension of the main roof works well.

Matching exterior materials is the second critical factor. Many Burnaby split-levels feature a combination of cedar siding (often horizontal lap or vertical board-and-batten), brick or stone veneer on the lower half-storey, and stucco on upper sections. Sourcing identical materials decades later is rarely possible, but your contractor can find close matches. For cedar siding, the profile width, exposure, and finish can be matched by a good mill — expect to pay $8 to $14 per square foot installed for custom-milled cedar that replicates the original. For brick veneer, salvage yards in the Lower Mainland occasionally stock period-appropriate brick, or you can use manufactured stone veneer that mimics the original colour and texture for $18 to $30 per square foot installed. One effective strategy is re-cladding the entire home (original and addition) with a new material like fibre cement siding or updated cedar, which creates a unified appearance and typically costs $15,000 to $35,000 for a full split-level exterior.

The multi-level floor plan of a split-level actually offers excellent opportunities for seamless additions. Because the home already has floors at different elevations, an addition can connect at whichever level makes the most sense structurally and functionally. Extending the lower level is often the most straightforward approach — the foundation walls are partially below grade, which means the addition's foundation height matches naturally. Extending the upper level allows for a larger kitchen or living area with views, though it requires careful structural support below. In either case, the interior transition between old and new should feel natural, with floor levels, ceiling heights, and hallway widths maintained consistently.

Window proportions and placement are a subtlety that many homeowners overlook. 1960s split-levels typically have specific window rhythms — horizontal sliding windows, picture windows with flanking casements, or vertically proportioned double-hung units arranged in regular patterns. Your addition's windows should respect these proportions even if you use modern, energy-efficient units. Placing larger windows on the addition than exist on the original home is a common giveaway that the section is newer. Modern vinyl or fibreglass windows can be ordered in custom sizes that match the original proportions while meeting current BC Building Code energy requirements.

Foundation and grade transitions deserve attention in Burnaby, where many split-level lots have moderate slopes. The addition's foundation must meet the existing foundation cleanly, with waterproofing and drainage details that account for water flowing downhill along the joint. A structural engineer experienced with Metro Vancouver's soil conditions (often clay-rich in Burnaby) and seismic requirements will design the connection between old and new foundations to perform as a unified system.

Budget-wise, achieving a seamless match adds roughly 10% to 15% to the cost of an addition compared to a more utilitarian approach. On a $250,000 addition, that's an extra $25,000 to $37,500 for material matching, custom millwork, and the additional design time needed to get proportions right. Most homeowners find this investment worthwhile — a well-matched addition not only looks better but also adds significantly more resale value than one that reads as an afterthought.
