Room Addition Process
Free Initial Consultation
We take the time to understand your goals by discussing your needs in detail, answering your questions, and addressing any concerns. This collaborative approach ensures that your vision is clearly defined—and fully understood—before we begin.
Design
We begin by thoroughly evaluating your space to develop a layout that’s both functional and tailored to your lifestyle. Using advanced 3D design technology, we create a realistic visual of your finished project—allowing you to explore every detail before construction begins. Once you’re fully satisfied with the design, we move forward with confidence, knowing the plan reflects your vision down to the last detail.
Blueprints & Permits
We take care of every technical detail—from producing accurate construction blueprints to managing the permitting process—ensuring your project meets all local building codes and zoning requirements. With our team handling the paperwork and compliance, you can move forward with confidence and peace of mind.
Demolition & Site Prep
For new structures, we handle all site preparation—excavating the land and establishing a solid, level foundation that supports long-term stability and structural integrity. Every step is performed with precision to ensure your addition is built on reliable ground from the start.
Framing
Once the foundation is ready, we begin the framing process, which involves constructing the structural framework for your addition. This includes carefully placing beams and studs that form the walls, floors, and roof of your new space, ensuring a solid and dependable structure for the project ahead.

The result is a cohesive, functional, and welcoming environment that elevates the entire property.

We install or upgrade plumbing, electrical, and HVAC systems to ensure your new space delivers optimal comfort, energy efficiency, and safety. Every component is integrated with precision and in full compliance with local building codes—so you can enjoy reliable performance from day one.
Insulation
We install high-quality insulation to ensure your new space remains energy-efficient and comfortable in every season. Proper insulation not only regulates temperature and reduces energy costs, but also enhances overall indoor comfort and noise control—creating a space that performs as well as it looks.
Drywall & Interior Paint
We finish your walls and ceilings with smooth, clean surfaces and apply high-quality paint in the colors of your choice. This final layer brings a polished, cohesive look to your space—enhancing both style and atmosphere with a flawless finish that reflects your personal taste.
Stucco & Exterior Paint
We complete the exterior with expertly applied stucco and high-quality paint, carefully matched to your home’s existing façade. The result is a seamless integration that enhances curb appeal and ensures your addition looks like it’s always been part of your home.

Installing tile is where design meets long-term durability—bringing both personality and performance to your new space. We guide you through selecting the perfect tile to match your style, whether you envision a clean, modern look or a timeless, classic feel. Once selected, our team installs each piece with expert precision, ensuring perfect alignment, consistent spacing, and a flawless finish. This step adds a refined, custom touch that elevates the space and is built to last.
Flooring
With the structure complete, we shift our focus to flooring—an essential element that ties the entire space together. Whether you choose hardwood, tile, laminate, or carpet, we offer a wide range of options to match your aesthetic and functional needs. Our team ensures a seamless transition with your existing floors or can install a completely new style throughout your home for a cohesive, refreshed look. Every installation is done with precision, blending beauty and durability to enhance the long-term value of your remodel.
Finishing Touches
From hardware to decorative accents, we complete your space with carefully selected finishing touches that reflect your personal style. Every detail is thoughtfully chosen and expertly installed to ensure a cohesive, polished look that brings your vision fully to life.
Inspection & Handover
Once the construction is complete, we’ll schedule a walkthrough to ensure everything meets your expectations. We’ll go over all the details of your new addition to make sure it integrates perfectly with your home. If any final adjustments are needed, we’ll take care of them. Our goal is to ensure that your new space feels like a natural extension of your home, and that you’re completely satisfied with the end result.
