Home Addition in Merriam Park

What’s included in a Knutson home addition

Foundation type assessment — we identify whether your home has a rubble-stone Victorian foundation or a more standardized 1930s bungalow foundation, since the addition’s structural connection depends entirely on which one it is.

Design and permitting — a design matched to your home’s specific era and style. All City of Saint Paul permits filed and inspections scheduled.

Foundation and framing — a custom tie-in approach for rubble-stone walls that bow or vary in thickness, versus a more conventional connection for block or poured foundations.

Electrical and HVAC extension — sized for the added square footage.

Plumbing — full rough-in for any addition including a bathroom.

Custom built-ins and finish work — millwork built in our own shop to complement Victorian or bungalow-era detail.

Why Merriam Park homeowners choose Knutson

A rubble-stone Victorian foundation doesn’t run straight or plumb the way a modern poured wall does, and connecting a new addition to it as if it did creates gaps and structural issues that show up within a few years. We assess the specific foundation condition wall by wall and design the tie-in accordingly, which takes more planning upfront but produces an addition that actually performs.

Whether the house above is a Victorian or a 1930s bungalow, our cabinet shop builds addition millwork to match that era’s detail, so the finished space reads as an extension of the house rather than a modern insert that clashes with the original construction.

What a Merriam Park Addition Actually Costs

A rear addition typically runs $75,000 to $140,000. Custom foundation tie-in work for a rubble-stone Victorian wall — furring, waterproofing detail, and a connection method built for an uneven surface — can add $10,000 to $20,000 on top of that, depending on how much of the foundation the addition actually touches.

How Long a Merriam Park Addition Actually Takes

Design runs four to eight weeks, and on a Victorian specifically, we spend part of that time assessing the actual condition of the rubble-stone foundation before finalizing the tie-in approach. Construction runs ten to sixteen weeks for standard foundation types, and closer to fourteen to eighteen weeks where custom stone foundation work is part of the scope.
