Old Stone Properties handles the full sequence of a build - planning, site work, structure, mechanicals, and finishes - so homeowners and developers work with one contract, one schedule, and one point of contact from start to finish.
Ground-up custom residential builds.
From site selection through final walkthrough, we deliver ground-up custom homes on schedule. Our team coordinates architects, engineers, and every trade so homeowners have a single point of accountability from foundation to finish.
Feasibility, scope and build strategy.
Pre-construction advisory for homeowners and developers weighing scope, budget, and timing. We review plans, flag constructability issues early, and outline a build strategy before shovels break ground.
Second stories, wings, structural expansions.
Additions that read as original to the house. We handle structural tie-ins, roof integrations, mechanical extensions, and finish work so the new footprint feels considered, not bolted on.
Coordination across every trade and phase.
Single-contract delivery with our project manager owning the schedule, permits, inspections, and trade sequencing. Fewer handoffs, cleaner site, faster decisions.
Office, retail and light commercial.
Ground-up and interior fit-out work for owners and tenants across Connecticut. We understand code compliance, ADA, and the operational realities of building on an active site.
Survey, grading, drainage and site prep.
Site work sets the ceiling on quality for everything above it. Our crews handle survey coordination, clearing, grading, drainage, and utility rough-in with the same rigor we bring to finishes.
Footings, slabs, walls and underpinning.
Poured walls, ICF, slab-on-grade, and structural underpinning for renovations. Every foundation is engineered to soil conditions and inspected before backfill.
Precision framing and load-bearing renovations.
Straight walls, plumb corners, and structural changes done to spec. We open floor plans, add spans, and stack second stories without cutting corners on the bones of the house.
HVAC, plumbing and electrical, sequenced.
We schedule mechanical trades so rough-ins land in the right order, inspections pass the first time, and finish work is not held hostage by a missed connection.
One PM, one schedule, permit to walkthrough.
A dedicated project manager runs the job end to end - budget, schedule, submittals, RFIs, and client updates - so nothing falls between the cracks.
A cross-section of custom homes, additions, kitchens, and site work delivered by our team. Every project runs through the same accountable process.
