How do I convert a closed kitchen to open concept in a 1970s NB home?

Converting a closed kitchen to open concept in a 1970s New Brunswick home is very achievable, but you must first determine whether the walls you want to remove are load-bearing. In most 1970s NB homes, at least one kitchen wall runs perpendicular to the floor joists and carries structural load from above. Removing it without proper engineering is dangerous and a code violation.

The first step is hiring a structural engineer to assess which walls are load-bearing. In New Brunswick, a residential structural assessment typically costs $500 to $1,200. The engineer will specify the size and type of beam (typically an LVL or steel beam) needed to replace the wall, the post locations, and whether the foundation can handle the point loads from the new posts. This assessment is required before your municipality or Regional Service Commission will issue a building permit, which is mandatory for any structural modification.

What to Expect During the Work

Once engineering is complete and the permit is in hand, your contractor will install temporary shoring walls to carry the load above while the existing wall is removed and the new beam is installed. This process typically takes 2 to 4 days for the structural phase. The total cost for removing a load-bearing wall and installing a beam in a typical NB home runs $3,000 to $8,000, depending on the span and whether steel or engineered lumber is used.

1970s NB homes often have several hidden issues that surface during an open-concept conversion. Galvanized plumbing is very common in this era and should be replaced during renovation because it corrodes internally and reduces water pressure. Budget $2,000 to $5,000 for re-plumbing the kitchen area. Electrical panels from this era are frequently 60-amp, which cannot support a modern kitchen with today's appliances. A panel upgrade to 100-amp or 200-amp costs $1,500 to $4,000 and is practically a requirement when opening up the kitchen.

You may also encounter asbestos in floor tiles (9-by-9-inch tiles were commonly used through the 1970s) and potentially knob-and-tube wiring in older sections of the home. Asbestos tile removal requires a licensed abatement contractor in New Brunswick and adds $1,500 to $4,000 to the project. Never attempt to remove suspected asbestos materials yourself.

Planning the New Open Layout

With the wall removed, you gain an opportunity to rethink the entire kitchen layout. The most popular approach in NB open-concept conversions is an L-shaped layout along the two remaining walls with a new island where the wall used to be. The island defines the kitchen space, provides seating that faces the living or dining area, and keeps the cook connected to the household.

Flooring continuity matters in an open-concept space. Luxury vinyl plank at $2,000 to $4,000 is the most practical choice for NB homes because it runs seamlessly from kitchen to living area, handles the humidity swings between Maritime summers and dry heated winters, and is fully waterproof near the sink and dishwasher. Matching the existing living room floor is another option, but hardwood near the kitchen sink and dishwasher is risky due to water exposure.

A full closed-to-open kitchen conversion in a 1970s NB home typically runs $50,000 to $80,000 when you include structural work, new cabinets, countertops, flooring, electrical upgrades, and plumbing updates. Book your contractor by March or April for a summer start, or consider the November-to-March window for potential savings of 10 to 15 percent.
