Types of Room Additions We Offer

At Quartz Construction, we provide a wide range of room addition services designed to enhance the livable space in your home. Some of the most popular room addition projects we undertake include:

Home Office Additions

As more homeowners embrace remote work, creating a dedicated home office has become one of our most requested services. We design functional and comfortable spaces that enhance productivity while seamlessly blending with the existing style of your home. Whether you need built-in storage, soundproofing, or customized lighting, we ensure your workspace meets your specific needs while maintaining a professional and inviting atmosphere.

Sunrooms

A sunroom is a fantastic way to bring in natural light and expand your living space. Whether you’re looking for a peaceful retreat to enjoy your morning coffee or a bright and airy space to entertain guests, a sunroom offers an affordable and effective solution. Designed to suit your home’s architecture and climate needs, our sunrooms provide year-round comfort while increasing your home’s value and aesthetic appeal.

Second-Story Additions

If you’re looking to add substantial living space to your home without sacrificing yard space, a second-story addition could be the perfect solution. This type of expansion not only increases square footage but also significantly boosts property value. A second-story addition allows you to create entirely new bedrooms, bathrooms, or even a separate living area, giving your home more versatility while maintaining its existing footprint.

Extra Bedrooms

Whether you’re preparing for a new family member or simply need more room, adding an extra bedroom is a great way to accommodate a growing household. An additional bedroom can serve multiple purposes, from a guest room to a home office or even a private retreat. We ensure that new bedrooms seamlessly integrate with your home’s design while meeting your space and comfort needs.

Garage Conversions

Many homeowners are transforming their garages into functional living spaces to maximize their home’s existing square footage. Whether you envision a home gym, a playroom for the kids, or a fully equipped guest suite, converting your garage is a cost-effective way to add usable space without the need for a full addition. Our expert team ensures that insulation, ventilation, and lighting are properly adjusted to create a comfortable and practical extension of your home.
