Sunrooms and Room Additions in Metamora and Lapeer County, Michigan
Adding a room is not the same job as remodelling one. It starts below ground, and it has to tie into a house that is already standing — the roofline, the siding, the gutters and the floor level all have to meet as though they were always that way.
Besides room remodels and
whole-house renovations, Timberland Construction builds sunrooms, three-season rooms and full additions across Metamora, Dryden, Lapeer, Grand Blanc and Davison. Foundation, framing, roof, windows, siding, and interior finish are all handled by
our own crew.
A Recent Sunroom in
Lapeer County
Knotty pine walls and a vaulted ceiling, two skylights let into the vault, six windows and a sliding patio door. On the shortest day of the year, with a foot of snow on the ground, the room is full of light.
Note the season. We build through Michigan winters — the frame goes up, gets dried in, and the interior work carries on while the ground is frozen.

What We Build
Sunrooms and Three-season Rooms
Full-height glazing, sliding or french doors, vaulted or flat ceilings, skylights. Insulated for three seasons or fully conditioned for four — we will price both.
Room additions
Bedrooms, family rooms, in-law suites, dining rooms. Poured foundation or crawl, framed, roofed, and tied into the existing structure.
Garage Conversions and Additions
Attached garage turned into living space, or a new addition built over or beside an existing one. Heated, insulated and finished to match the rest of the house.
Second-storey and bump-outs
Where the lot will not take a footprint, the room goes up rather than out.
Three or Four Seasons?
- A THREE-SEASON room is insulated and finished but not on the house HVAC. Cheaper, faster, and comfortable roughly March to November in this part of Michigan.
- A FOUR-SEASON room is fully insulated, conditioned and counts toward the finished square footage of the house — which matters when you sell. It costs more and takes longer.
Most people who tell us "three-season" end up wanting four once they price the difference against how much they would actually use the room in January. We will show you both numbers.
Permits, Foundations, and Tie-in
An addition needs a permit and an inspected foundation. We pull the permit and schedule the inspections. The tie-in — where the new roof meets the old — is the detail that separates an addition that looks original from one that looks bolted on, and it is where our carpentry background earns its keep.
How Long It Takes
A sunroom on a crawl foundation is typically four to eight weeks from breaking ground. A full addition with a poured foundation runs longer and is weather-dependent at the foundation stage.
