Home Additions
Add space. Add style. Add value.
Transform Your Space. Elevate Your Home's Value.
Your home should work as hard as you do - and a well-planned addition does exactly that.
Whether you need a primary suite that feels like a retreat, a kitchen that finally fits how you cook, or space for aging parents or grown kids who boomerang back, we help you see what's possible.
You're making an investment in possibly your largest asset, your home.
Here's our approach: We start by really listening.
- What's frustrating you about your current layout?
- What would make daily life easier?
Then we apply our expertise to design an addition that doesn't just solve today's problems - it unlocks serious value in your home.
Because you're not just adding square footage. You're making a strategic investment in your largest asset.
And unlike the typical architect-then-contractor shuffle, we handle both design and construction.
One team, one vision, one point of accountability.
That means your project stays on budget, on schedule, with one single point of contact to manage all that goes into a custom remodel.

Popular Home Additions and Extensions Types
Second Story Additions
Add an entire floor to your Cape or ranch home. Create 3-5 bedrooms upstairs with full bathrooms, walk-in closets, and proper ceiling height—all without expanding your foundation or losing yard space.
Primary Suite Additions
Build the luxurious master bedroom retreat you've always wanted. Spacious bedroom, spa-quality bathroom, walk-in closets, and complete separation from kids' bedrooms. Popular for both first-floor and second-floor additions.
Kitchen Addition
Expand your cramped kitchen into a modern space with room for an island, dining area, and proper storage. Open up walls to create flow between kitchen and family room.
In-Law Suite Additions
Create independent living space for aging parents or adult children. Bedroom, bathroom, kitchenette, and separate entrance—supporting multigenerational living with privacy and dignity.
Family Room & Great Room Additions
Extend your living space horizontally with rear or side additions. Perfect for open-concept entertaining or dedicated space for kids' activities.
Home Office Additions
With more professionals working from home, dedicated office space with proper soundproofing, natural light, and separation from household activity has become essential.
Find Your Perfect Addition
Additions or Extensions by Home Style
Different Long Island home styles require different addition strategies. We specialize in all three major architectural types
Cape style additions
Transform your Cape-style home with second-story additions, dormer expansions, or rear additions that maintain classic charm while solving the low-ceiling, cramped-bedroom problems these 1950s starter homes are known for.
Ranch Style additions
Complete your ranch home by adding a second story or expanding horizontally. Preserve the single-level accessibility buyers love while gaining the bedrooms and bathrooms modern families need.
Split-Level Additions
Solve the choppy, disconnected layout that frustrates split-level owners. Strategic additions create open-concept flow while maximizing your home's unique multi-level architecture.
How Home Additions Increase Your Property Value
A well-executed addition does more than give you extra space—it makes your home more competitive when it's time to sell.
Quality additions typically return their investment at resale, and in Long Island's competitive market, homes with professional additions often sell faster than comparable properties that feel cramped or outdated.
Why Different Home Styles Benefit Differently
Cape Cod Additions complete the home's intended design. Most Capes were built as "expandable" starter homes in the 1950s, so a second-story addition looks natural and appeals to buyers seeking traditional charm with modern space. These additions often return 65-80% at resale.
Ranch Additions preserve the single-level living that many buyers want while adding square footage efficiently. Whether you go up or out, the clean lines and accessible layout remain intact—a major selling point for aging-in-place buyers and families who prefer one-floor living.
Split-Level Additions solve the biggest complaint about split-levels: Small bedrooms, small closets, and a barely usable master bathroom. Strategic additions create the open-concept flow that today's buyers expect while maximizing the unique multi-level layout. Updated 4-bedroom houses sell at a premium to their 3-bedroom counterparts. Oftentimes by more than the cost of the addition!
Why Home Additions Beat Moving
In Long Island's real estate market, oftentimes 'moving' up to a larger home means moving out of your neighborhood, or moving to an area that's too far out of reach. Adding the square footage you need is the smart way to get into the house you've always dreamed of.
- More affordable than buying up as typical additions cost 40-60% less than moving to a larger home
- Avoid closing costs, realtor fees, and moving expenses (typically $30,000-$50,000)
- Keep your current mortgage rate instead of refinancing at higher rates
- Lower property taxes than buying a bigger house
- Build equity immediately through increased home value
- Stay in your school district, and kids keep their friends and teachers
- Keep your commute, neighbors, and community connections
- No competition with other buyers in a tight market
- The home you purchase may need updates, too
- Avoid the stress and disruption of packing, moving, and unpacking
- Customize exactly what you want instead of compromising on an existing home

The Design-Build Advantage
Instead of juggling separate architects and contractors, you work with a single design-build team from concept to completion.
The result? No miscommunication between parties, no finger-pointing when issues arise, and no budget surprises halfway through your project. Your addition flows seamlessly with one accountable partner managing every detail.
What Design-Build Means for Your Project
CIC directs your architect, so design and construction work from the same scope. That gives you:
- Architectural design by the licensed architect we direct, with complete permit and paperwork management
- On Staff Interior Designer with every project. Far exceeding the designs done by typical architects, our team gives a complete set of interior design drawings.
- Material selection guidance in our private showroom
- Expert construction oversight with dedicated full-time project managers
- Seamless coordination from the same specialists handling your entire project
- One point of contact and one team accountable for results
Why This Matters for Home Additions
Additions are complex. They require integrating new structure with old, matching existing finishes, coordinating multiple trades, and solving problems that only appear once walls are open. When your designer and builder are the same team, solutions happen faster, costs stay predictable, and quality remains consistent.
Starting an Addition With or Without Plans
Most additions start with a question, not a drawing. Can we go up a floor? Can the kitchen push into the backyard? You don't need plans to ask. Through our Project Development Agreement, we measure and 3D-scan your house, then develop floor plans, renderings and construction pricing for the addition. If an architect has already drawn it, we'll review the plans and give you an estimated budget. Those plans usually stop at the structure, so our design team designs the new kitchen, baths, lighting and flooring at no extra charge.
