What’s the Difference Between Remodeling and a Home Addition?

While remodeling transforms the inside of an existing space, an addition expands your footprint—giving you more room to live, work, and relax. Additions may include:

Remodeling reshapes what you already have. An addition gives you more of what you need.

Why Cape Cod Homeowners Choose Capizzi Home Improvement for Their Additions

Our Unique 10-Step Design/Build Process

At Capizzi Home Improvement we understand that frequent communication and attention to detail is essential to a smooth and successful renovation project.  Our ultimate goal is to exceed your expectations.  That is why we adhere to our rigid, two-phase, 10-step design/build process.

The Design Phase (Steps 1-5)

01

Complimentary Consultation

Our project consultant meets with you to thorough­ly evaluate your project. We want to completely understand your needs, wants, and vision.

02

Preliminary Design

We measure, photograph, and document your home’s existing conditions, custom designing a
solution specific to your needs.

03

Intermediate Design

We’ll review your budget and project scope together, and you’ll have the opportunity to approve the preliminary designs before moving forward.

04

Final Design

With your project consultant and designer by your side, we’ll help you choose finishes, confirm the final design, and walk you through the project details step by step.

05

Construction Agreement

We wrap up by putting together a complete build-ready package, finalizing the paperwork so you’ll know exactly what to expect when construction begins.

The Build Phase (Steps 6-10)

06

Orientation Meeting

A production manager is assigned to your project. He will manage the day to day operations of your project, review your schedule, & address any concerns or special requests.

07

Pre-Construction Meeting

Before we begin your project, a meeting is held to walk-through
the procedures, production schedule, specifications and construction plans. We address any questions or concerns you may have prior to starting.

08

Production

During this stage our team members will ensure that your project runs smoothly, keeping the job site as clean and organized as possible.

09

Completion

We will conduct a final walk through to ensure that every detail is complete.

10

Warranty

Our team stands behind our work with a 5-year unconditional labor warranty and three annual inspections.

FEATURED ADDITION: ACCESSORY DWELLING UNITS (ADUs)

With housing costs rising and flexible living on the rise, ADUs (Accessory Dwelling Units) are gaining popularity across Cape Cod. Whether it’s a backyard cottage, converted garage, or in-law suite, ADUs offer:

Ask us about zoning requirements and design options specific to your town—many Cape municipalities now encourage ADU construction.
