Custom Home Additions & Estate Structures in London, Ontario

Second storeys, rear additions, timber pavilions and poolside cabanas, designed to look like they were always part of the property. We handle the drawings, permits, footings and every finish, with Patrick on site from the first dig to the final walkthrough.

Space That Looks Like It Was Always There

From a second storey on a London century home to a timber pavilion beside a Kilworth or Lambeth pool, we design, engineer and build every addition and estate structure in-house, so one team is accountable for the footings, the structure and the final trim.

Honest material guide

Home Addition vs. Moving: Is an Addition Worth It in London, Ontario?

An addition isn’t always the right answer. Here’s an honest look at your options.

For families in London and nearby towns who love their street, their lot and their schools — but have outgrown the floor plan.

Option 1 of 3

Home addition

Stay & expand

Lifespan
Life of home
Upkeep
Like your home
Investment
Premium

Why homeowners choose it

  • Keep your neighbourhood, schools and mature lot
  • Designed around exactly how your family lives
  • Adds lasting value to the home

Honest trade-offs

  • Design and permits take time
  • Living through construction

Where it belongs: Families who love where they live but need more space.

Option 2 of 3

Covered porch / sunroom

Lighter footprint

in-lite PRO lighting
Lifespan
25+ yrs
Upkeep
Low
Investment
Mid
Warranty
5-yr lighting manufacturer

Why homeowners choose it

  • Faster and lower cost than a full addition
  • Brings the outdoors in
  • Pairs beautifully with built-in lighting and retractable screens

Honest trade-offs

  • Less year-round living space unless insulated

Where it belongs: Adding a three-season room for evenings outdoors.

Option 3 of 3

Moving

The alternative

Lifespan
—
Upkeep
Start over
Investment
High, non-recoverable

Why homeowners choose it

  • Immediate change of space

Honest trade-offs

  • Commissions, land transfer tax, legal and moving costs — none of which add value
  • Often a compromise on location

Where it belongs: When your lot or neighbourhood no longer fits.

Patrick’s field verdict

We’ll tell you if an addition doesn’t make sense for your home — we’d rather earn your trust than sell a project.

Honest material guide

Helical Piles vs. Concrete Footings: The Foundation Under Your Deck

What’s under your deck matters as much as what’s on top — especially with Southwestern Ontario’s frost.

Built for the heavy clay soils and deep winter frost common across London, Middlesex County and the surrounding townships.

Option 1 of 2

Helical piles

Our preferred foundation

Lifespan
50+ yrs
Upkeep
None
Investment
Upper-mid

Why homeowners choose it

  • Installed in hours — framing can start the same day
  • Minimal digging, no concrete trucks on your lawn
  • Set below the frost line and load-rated as installed

Honest trade-offs

  • Higher cost per post than poured footings
  • Requires specialized equipment

Where it belongs: Composite and PVC decks, additions, and any project where you want zero heaving.

Option 2 of 2

Poured concrete footings

Traditional

Lifespan
30+ yrs
Upkeep
None
Investment
Mid

Why homeowners choose it

  • Proven and widely accepted
  • Lower material cost

Honest trade-offs

  • Excavation, soil piles and curing delays
  • Frost heave risk in clay if not deep or well-formed

Where it belongs: Sites where piles aren’t practical.

Patrick’s field verdict

For premium decks, helical piles are usually worth it: a faster build, a cleaner yard and a foundation that won’t move.

Common questions

Home Addition & Estate Structure Questions, Answered

What kinds of additions do you build?

Second storeys, dormers, rear and ground-floor additions, garage and mudroom additions, plus timber pavilions, covered porches and pool houses.

Do you handle drawings, engineering and permits?

Yes. We coordinate the drawings and any engineering, submit the permit application to your municipality and manage every inspection.

Will the addition match my existing home?

That's the goal on every project. We match rooflines, siding, trim and interior finishes so the new space looks original to the house.

Can we stay in the home during an addition?

In most cases, yes. We protect the existing house, control dust and tidy up daily. We'll talk through what to expect for your project at the consultation.

Do you build additions outside London?

Yes. We build across our north-west territory, from Komoka and Kilworth to Strathroy, Ilderton, Lucan and Grand Bend. Larger estate projects just beyond that area are worth a conversation.

What if my project isn't the right fit for Quality Carpentry?

We'll tell you honestly from the first conversation. If your scope, timing or location isn't something we can give our full hands-on attention, Patrick will gladly recommend a trusted contractor or trade specialist from our network.

“We had to wait a bit but the wait was worth it. Our new front porch looks amazing. They even helped us out with a couple of side fences, something they don't usually do. I work awake nights and they were very accommodating to my schedule.”
