Interior Remodeling Built Around How You Actually Live
Cosman Construction is a boutique design-build firm serving homeowners and property owners across Boulder, Larimer & Weld Counties who need home remodeling contractors they can trust with the spaces they use every day.
We handle the full interior scope — kitchen remodels, bathroom renovations, structural wall removal, whole home renovations, mechanical coordination, and finish upgrades — all under one contract with Alex Cosman present throughout.
Every project starts with a detailed design, a written scope, and a real estimate before any work begins. If your project extends beyond the interior, our exterior remodeling and home addition services can run in parallel so everything moves as one coordinated effort.
Homeowners across Fort Collins, Windsor, Loveland, Boulder, Louisville, Lafayette, Erie, Longmont, Firestone and the surrounding Front Range have trusted us with their most personal spaces — and they come back because a team genuinely invested in the outcome is hard to find at this level. Schedule a conversation with Alex to get started.
What We Build
Kitchen Remodeling
A kitchen remodel is the highest-return interior investment most homeowners make — and the most disruptive if it isn't sequenced correctly. We design kitchens that solve the actual problems with your current space — poor flow, inadequate storage, outdated finishes — rather than simply replacing what's there with something newer.
Bathroom Remodeling
A bathroom untouched since the mid-nineties isn't just dated — it's costing you in comfort and property value every day it stays that way. We handle full renovations from layout reconfiguration through tile, fixtures, vanities, and lighting, with the waterproofing detail that separates a remodel that holds up from one that doesn't.
Structural Wall Remodel & Reconfiguration
Opening a floor plan isn't as simple as identifying which wall to remove. It requires understanding the structural system, engineering the correct beam and post solution, and coordinating the mechanical, electrical, and plumbing running through the walls being touched. We manage the full scope from engineering coordination through drywall and finish.
Whole Home Renovations
When every room needs attention, the risk isn't the scope — it's the sequencing. A renovation that isn't phased intelligently turns into a project where trades wait on each other, finishes get damaged by work that should have happened first, and the family loses livability everywhere at once. We coordinate every trade under one schedule and hold the same standard in the last room as the first.
Mechanical Coordination
Interior remodels almost always touch mechanical systems — HVAC, plumbing, electrical — and how that coordination happens determines whether the finished space performs correctly or creates problems later. We work with licensed trade partners whose work meets Boulder, Larimer & Weld Counties code and our own standard.
Finish Upgrades
The right finish upgrades — new flooring, updated trim, replaced hardware, refreshed lighting — can shift how an entire home feels without touching a single wall. For homeowners weighing a full remodel against a finish upgrade first, we'll tell you honestly which one your space actually needs.
Why Hire a Design Build Company for Your Interior Remodel
Most interior remodeling projects above a certain scope require more than a contractor — they require design drawings for permitting, structural engineering for wall removal and beam specifications, and often an interior designer to ensure the finished space reflects your vision as well as it performs structurally. Coordinating those relationships separately is the homeowner's responsibility on a traditionally contracted project.
With Cosman Construction, that coordination is handled for you. We work directly with interior designers, architects, and structural engineers as needed — assembling the right team for your project and managing every professional relationship under one contract so the design intent survives all the way through to the finished space.
Your Outdoor Living Project Starts With a Plan
The remodels that go sideways share a common thread — the planning conversation was too short and the build conversation started too soon. We ask every hard question before the first wall opens so the answers don't become surprises mid-project.
Step 1: Consultation & Design
Every interior remodel starts with a conversation with Alex in your home — looking at the actual space and understanding how you use it before any design decisions are made. From there we produce design drawings, a written scope, and a real estimate so you know what the project costs before you commit to anything.
Step 2: Project Begins
Once design is approved and permits are in hand, work begins on a defined schedule — demo, rough-ins, structural work, finishes — each with a target date. Alex is reachable throughout, and any change that affects scope, timeline, or cost gets communicated before it affects the project.
Step 3: Project Completion
Alex walks the finished space against the original scope — every room, every finish, every detail. Anything that doesn't meet standard gets corrected before your walkthrough. Permits closed, inspections handled. We're done when there's nothing left on the list.
A note on the design phase: You're not locked into completing construction with us. If you take the design we've produced and work with another contractor for the build, that's completely your call. If you choose to move forward with us, the design fee is credited toward the project cost.
