More space. Better flow. Built to match your home.
The best additions feel like they have always been part of the house. Rooflines meet cleanly, finishes align, and the new rooms work with your daily routine. Ivy Lea Construction designs and builds home additions across Buffalo and Western New York with thoughtful planning, careful craftsmanship, and clear communication from the first conversation to the final walkthrough.
Design-build remodeling that feels seamless
Our design-build approach brings planning, selections, and construction together under one accountable team. That means faster decisions, fewer surprises, and a finished space that looks right and lives even better. If you are comparing home remodeling services or looking for a remodeling contractor who can manage both design and construction, we make the process straightforward.
What We Build
Whether you need a room addition contractor for a single space or home addition contractors for a full expansion, our team handles the full scope with care.
Permits, codes, & structural details
Additions touch structure, mechanicals, and finishes. We handle site plans, permits, and inspections, and we build to current codes. That includes load paths and beam sizing, energy code insulation and air sealing, egress and safety glazing, and the right HVAC, plumbing, and electrical. As one of Buffalo’s trusted home renovation contractors, we focus on comfort, durability, and clean details you can see and feel.
Tie in that looks seamless
A successful project blends old and new. We match siding profiles, window proportions, trim, and interior finishes so nothing looks tacked on. Proper flashing, water management, and air sealing at every connection protect the structure and help the addition perform through Buffalo winters and humid summers. This is where experienced home remodeling companies stand out.
Let’s plan your addition
An addition is a chance to improve performance. We specify the right insulation levels for Western New York, seal air leaks before finishes go in, and size systems with load calculations. The result is a quiet, comfortable room in January and July.

FAQs About Additions
Can you make the addition look like it has always been there?
Yes. We match rooflines, siding profiles, trim, window proportions, flooring transitions, and interior finishes so the old and new flow together without awkward seams.
Will I need to move out during construction?
Many clients remain in the home. We set up dust control, safe paths, and clear work zones. For major kitchen or bath tie-ins, a short off-site stay can be more comfortable.
What affects the cost of a home addition the most?
Foundation type, roof complexity, structural spans, kitchen or bath fixtures, window and door packages, and finish selections. Early clarity on layout and finishes keeps budgets predictable.
