Home Addition in Kingfield

What’s included in a Knutson home addition

Existing structure assessment — we map what’s original bungalow construction versus what was added later, often without a full permit history, before designing anything new.

Design and permitting — a design that accounts for foundation type and ceiling height differences between original construction and any prior addition. All City of Minneapolis permits filed.

Foundation and framing — new construction tied into whichever section of the house — original or previously added — makes the most structural sense.

Electrical and HVAC extension — sized for the added square footage, accounting for whatever wiring or ductwork a previous addition already introduced.

Plumbing — full rough-in, evaluated against whatever drain layout previous work left behind.

Custom built-ins and finish work — millwork built in our own shop to tie the whole house together visually, old sections and new.

Why Kingfield homeowners choose Knutson

A Kingfield bungalow that’s already had a rear addition or converted porch doesn’t have a simple, single-era structure to build on top of, and assuming it does is how a new addition runs into foundation or framing surprises mid-project. We map what’s actually there — section by section — before finalizing a design, so the plan we price is the plan we can build.

That mapping also means we can often tie a new addition into whichever existing section makes the most structural sense, rather than defaulting to the original foundation simply because that’s where the house started.

What a Kingfield Addition Actually Costs

A rear addition on a Kingfield bungalow typically runs $70,000 to $130,000. When a home has an undocumented prior addition that needs foundation transition work to tie into cleanly, that range can climb by $10,000 to $25,000 depending on what we find once we’re actually mapping the existing structure — which is exactly why that mapping happens before we finalize a number, not after.

How Long a Kingfield Addition Actually Takes

Design typically runs four to eight weeks, though a Kingfield home with an unclear addition history sometimes needs an extra week or two of on-site investigation before we can finalize the structural plan. Construction runs ten to sixteen weeks once that mapping is done and the design reflects what’s actually there, not what the original blueprints — if they even still exist — say should be there.
