Home Additions & Expansions FAQs

What is a home addition or expansion?

A home addition or expansion is when you build new space onto your existing house, such as extra bedrooms, a larger kitchen, a second story, or an in-law suite. It lets you grow in place without moving.

What types of additions can you build?

We build many types of additions, including room additions, bump outs, second story additions, garage conversions, in-law suites, larger kitchens, and expanded living rooms. Our team helps you design an addition that fits your home and lifestyle.

Do you help with design and permits?

Yes. We guide you through planning, design coordination, and permit support. We are familiar with local building codes in Massachusetts, Rhode Island, and Northern Connecticut so your project is safe and compliant.

How long does a home addition usually take?

Smaller additions and bump outs may take a few weeks once construction begins. Larger or multi-room additions can take several months from planning to final finishes. During your consultation, we provide a timeline based on your specific project.

Can we stay in the home while work is being done?

In many projects, you can stay in the home, but you should expect noise, dust, and restricted access to some areas. For major structural work, we will review safety and comfort with you so you can decide if staying or temporarily relocating is better.

Are you licensed and insured for home additions?

Yes. Antoniel Renovations holds an Unrestricted Construction Supervisor License and is fully insured. We are also certified for MA Lead Paint Abatement, which is especially important for older New England homes.

How much does a home addition cost?

Cost depends on the size, design, materials, and structural work required. Some projects focus on a single room, while others add multiple rooms or floors. The best way to know your budget range is to schedule a consultation and detailed estimate.

Do you work with both homeowners and investors?

Yes. We help homeowners who want to expand their forever home and investors who want to increase property value and rental potential. Our team understands budgets, timelines, and long-term return on investment.
