Major Renovations

Major Home Renovations in North Vancouver

A major renovation is not a bigger kitchen remodel. It is construction that touches the bones of the house — walls that carry load, floors that span, and the foundation everything sits on. Twin Peaks Construction has built on the North Shore for three generations, and the work we are known for is the heavy, structural side of big jobs. If you are opening up a plan, adding floor area, or fixing problems that show up in a house that has moved, this page explains what you are actually taking on.

What makes a renovation "major"

The line is simple: the moment you change how the house carries weight, you are in major-renovation territory. Moving or removing a load-bearing wall, raising a ceiling, cutting a new opening through a floor, adding a storey, or extending the footprint all re-route load paths that the original builder set decades ago. Everything above has to find a new way down to the ground.

These projects also tend to expose the foundation. Once walls are open and finishes are off, you can finally see what the house is standing on — and on many older North Shore homes, that is where the real scope lives. A renovation that started as a layout change often becomes a structural project the day the drywall comes down.

If your plans involve any of that, you want a builder who works in structure every day, not one who sees framing as something to get past on the way to the finishes.

The structural backbone of a big reno

Most of the budget and most of the risk on a major renovation sit in work the finished house will never show. The common structural moves we handle:

  • Re-engineering load paths — replacing walls with beams and posts so weight transfers cleanly to the foundation when you open up a plan. See load-bearing wall removal.
  • Foundation work under an existing home — from targeted foundation repair to full foundation replacement and underpinning when you deepen or add below.
  • Lifting a settled house — raising a home to level it, replace the foundation, or gain height below.
  • Adding floor area — additions and second-storey additions, where the existing structure and foundation have to be verified before they carry anything new.
  • Rebuilding compromised framing — when rot or old damage has reached beams, posts, joists or sheathing, we rebuild the affected structure to an engineered detail. See structural repair.

Get this layer right and the finishes last. Get it wrong and no amount of tile or millwork hides a floor that bounces or a wall that cracks every winter.

Where the structural engineer comes in

Any time load changes, a BC structural engineer should be sizing the beams, posts and connections — and the City of North Vancouver or District will want that documentation for permits. We work alongside structural and, where the site calls for it, geotechnical engineers on nearly every major renovation. On a sloped or filled North Shore lot, soil conditions drive foundation design as much as the house does.

Bringing the engineer in early is cheaper than bringing them in late. We would rather have a detail drawn before we open a wall than discover a surprise and stop the job to wait on a design. If you already have an engineer, we build to their drawings; if you do not, we can point you to ones we have worked with.

How a major renovation runs, start to finish

A big job that goes well is a job that was scoped honestly before anyone swung a hammer. Our process:

  • Walk-through and feasibility — we look at what you want against what the house and lot can actually do.
  • Design and engineering — drawings, structural design, and a permit set. This is where load paths and foundation strategy get decided.
  • Permitting — submission to your municipality; North Shore permit timelines are a real part of the schedule, not an afterthought.
  • Demolition and discovery — opening the house up, confirming existing structure, and resolving anything the drawings could not predict.
  • Structural work — foundations, beams, framing, the load-carrying core.
  • Rebuild and finishes — everything you will actually see, built on top of sound structure.

Older North Shore homes and seismic

A lot of North Vancouver and West Vancouver housing stock predates current standards, and a major renovation is the natural time to deal with it. When a house is already open to the framing, the cost of strengthening it is a fraction of what the same work costs as a stand-alone project. If your home is older, ask us about seismic upgrades and major structural repairs while the walls are open.

We serve North Vancouver, West Vancouver and the wider North Shore. These are our home streets, and we know how the older homes here were built.

Is your project a fit for Twin Peaks?

We are built for the heavy end of the market — structural renovations, foundation work, additions, and whole-home projects where getting the bones right is the whole game. If you are planning a single-room refresh or a cosmetic update, a smaller finishing contractor will usually serve you better and cheaper, and we will happily say so.

If your project involves moving load, touching the foundation, adding floor area, or fixing a house that has moved, that is squarely our work. Not sure which side of the line you are on? Start with our free structural check, or call us at (778) 882-8001 and walk us through it. We will give you a straight read on scope before you spend a dollar on design.

Frequently asked questions

What counts as a major home renovation versus a remodel?

The dividing line is structure. A remodel updates finishes and fixtures within the existing shell. A major renovation changes how the house carries weight — removing or moving load-bearing walls, adding a storey or an addition, cutting new openings, or working on the foundation. Once load paths or the foundation are involved, you are into major-renovation scope and the permit, engineering and sequencing all change accordingly.

Do I need a structural engineer for my renovation?

If your project changes load anywhere — removing a wall, adding floor area, altering the roof, or working on the foundation — yes, a BC structural engineer should size the beams, posts and connections, and your municipality will want that documentation for the permit. We work alongside structural and geotechnical engineers on nearly every major job and build to their drawings. We bring them in early rather than late, which almost always saves money.

We found rot in the framing during demolition. Can you handle that?

Yes. When rot or old damage has reached structural members — beams, posts, joists or sheathing — we rebuild the affected framing to an engineered structural detail so it carries load properly again. That structural rebuild is core to what we do. Discovery during demolition is normal on older North Shore homes, which is one reason we scope these projects with room for it.

How long does a major renovation take on the North Shore?

It depends on scope, but plan in phases rather than weeks. Design and engineering come first, then permitting — North Shore permit timelines are a real part of the schedule and outside any builder's control. Construction then runs through demolition, structural work, and rebuild. Foundation work, house lifting, or additions extend the timeline further. We give you a realistic schedule after the walk-through, not an optimistic one up front.

Do you take on small renovations too?

We focus on the heavy, structural end — foundations, load-bearing changes, additions, house lifting, and whole-home projects. For a single-room refresh or a cosmetic update, a smaller finishing contractor will usually serve you better and for less, and we will tell you so honestly. If your job involves structure, foundations, or added floor area, that is exactly our work. Call (778) 882-8001 and we will give you a straight answer on fit.
