Major Home Additions
EXPERT PLANNING / SUPERIOR WORKMANSHIP / 100s OF SATISFIED CLIENTS
Our clients embark on major additions for many reasons. Some fall in love with a home that will only be perfect once it’s expanded. Others have a growing family, or changing needs.
If you love where you live, your home or cottage can grow along with you. Over the years, DeCarli Contractors has helped hundreds of homeowners reimagine their spaces with expertly designed, beautifully executed home additions. Many want additions that blend seamlessly with the original structure, while other clients want to make a bold statement. Whatever the case, we deliver.
From concept to completion, DeCarli brings detailed planning, attention to detail and superior workmanship to every project. Whether you plan to add a second story, expand your kitchen, build an in-law suite, or create a larger living area, we will help you plan and build a space that fits your life today—and grows with you tomorrow.
TYPES OF HOME ADDITIONS
Every home and family is different, which is why we offer a range of addition types tailored to your goals, property layout, and long-term needs.
Second-Story Additions
Perfect for bungalows or single-level homes. Gain extra bedrooms, bathrooms, or even a full second floor without expanding your home’s footprint. Ideal for growing families, multi-generational living and enhancing long-term flexibility while maximizing your lot without sacrificing outdoor space.
Side or Rear Extensions
Add square footage to your ground floor for larger kitchens, family rooms, sunrooms, or expanded bedrooms. This creates an open, modern layout that’s ideal for entertaining, open-concept living, and accessibility.
Private Living Quarters
Accommodate aging parents, guests, or create private living quarters with separate entrances, bathrooms, and living areas. Increasing your home’s usability and adaptability is ideal for multi-generational families, accommodating guests, or flexibility for the future.
We’ll help you determine which addition type best fits your property and lifestyle.
WHY HOMEOWNERS CHOOSE HOME ADDITIONS
More Space, Better Living
Home additions give your family the flexibility to adapt your space to changing needs. Whether it’s a nursery, office, or sun-filled breakfast nook, more space means more opportunities to enjoy your home.
Increase Property Value
Well-planned home additions can dramatically enhance resale value. Buyers appreciate added square footage, especially when it blends seamlessly with the original design. It’s an investment in both comfort and future potential.
Stay In The Home You Love
Stay in the neighborhood you love and improve your existing space instead of relocating. Avoid the stress of bidding wars, new mortgages and starting over. A home addition is often more rewarding, both emotionally and practically.
Customize Your Environment
Adding to your existing home allows for complete customization. Control the layout, design finishes and overall flow of your expanded space. With our team’s guidance, you’ll create something uniquely yours.
OUR PROVEN PROCESS
Over the course of more than 20 years building custom homes and cottages, we have come to realize that everyone wants one thing: predictability.
A predictable outcome, a predictable cost, a predictable schedule, predictable quality and craftsmanship.
1. Connect
The best way to start is by meeting in person. During this first meeting we’ll answer any questions you may have and discuss the potential project you are envisioning. With enough conceptual information, we’ll determine if we can meet your needs in terms of budget and schedule, and detail where DeCarli Contractors can add value.
2. Detailed Estimate
In our second meeting, we will discuss your project in greater detail. We don’t need every specification, but we do want to define some general parameters so that we can provide you with a detailed and well-contemplated estimate. We’ll ask you to bring photos, notes, sketches and organized thoughts for us to refine your concept and bring context to your envisioned build. With this estimate, we hope to provide you with a much clearer understanding of where construction costs come from and how they apply to your potential project.
3. Design & Finishing Specifications
Now it’s time to work out all the details. Our team of BCIN-Certified designers and in-house finishing experts will work with you to create construction plans and finishing schedules using 3D modeling and interior rendering software. Our team will gather samples and product-specific information to help you sort through the many options. We will present you with curated choices based on your specific aesthetic tastes and budget. Making this process as easy as possible is our job and our promise to you.
4. Fixed-Price Quotation
With the previous step complete, we can now move on to producing our fixed-price, inclusive quotation, which spells out the specifics of your entire build and the price that you will pay. It includes approximately 300 line items and the entire building process in chronological order from the first shovel in the ground to the last drop of paint. The price quoted is the price you pay.
5. Construction Schedule
The next action is to build out a construction schedule that involves booking trades, ordering materials and scheduling the various stages of the build. DeCarli construction schedules are realistic, so our builds tend to finish on time.
6. Construction
This is the part that we look forward to the most. Since we’ve put together a construction schedule that we can stick to, we tend to stay on track. And remember, once we start your project, we are there every day until it’s complete. We pride ourselves on finishing our projects on time, to your complete satisfaction. As we build, we will keep you up to date on our progress with phone calls, on-site visits and live video walk-throughs. The smoothest builds involve well-informed clients.
7. Handover
As we do our final walk-through with you, we will explain what you will need to know about your new home or cottage: the features and functions of your HVAC system, smart lighting, how to program appliances, and general maintenance needs. In a year’s time we will return and do a full inspection and address any new-build requirements.
