Home Additions in Squirrel Hill, PA

If you’ve outgrown your home but love where you live, a well-planned addition can change everything. Whether it’s a larger kitchen, a new primary suite, a second story, or space for extended family, we handle everything from zoning and permitting to final punch list.

Our design-build model means we look at the big picture—how the addition will tie into your existing home, what systems need to be updated, and how to make the space feel like it’s always been there. No handoffs between designer and builder, and no surprises halfway through.

Over the last 15+ years, our team has built dozens of homes from the ground up across Pittsburgh—from infill lots in tight city neighborhoods to new builds on wide-open land. If you’ve got a lot and a big idea, we know how to take it from dirt to done.

Our design + build process keeps everything under one roof: we handle the architecture, permitting, selections, materials, and construction—no bouncing between firms or chasing down answers. You get a clear plan, one point of contact, and a home that’s built to work beautifully for how you live.

The kitchen does a lot of heavy lifting in your home—it’s where people gather, where meals happen, and where the day starts and ends. We’ve remodeled everything from compact galley kitchens to wide-open spaces with massive islands and hidden storage.

Our design-build team will help you figure out what actually works for your family—whether it’s better lighting, more prep space, smarter appliance placement, or adding a pantry. We’ll walk you through layout options, cabinetry styles, and finishes that make sense for your lifestyle.

Bathrooms should work well and look good—but they also need to hold up to daily life. Whether you're dealing with poor layout, dated fixtures, or lack of storage, we’ll help you reimagine the space with better function and smarter design.

We’ve built everything from sleek powder rooms to spa-style primary bathrooms. We’ll guide you through materials that hold up to moisture and wear, storage solutions that actually work, and layout changes that make a big difference. We also flag issues like water pressure, ventilation, and code—before you even start.

Your private retreat should feel effortless, elegant, and entirely your own.

From reimagining layouts to creating spa-inspired baths and tailored dressing spaces, Marvista provides custom home remodeling solutions that transform primary suites into tranquil sanctuaries designed for comfort, luxury, and seamless living.

Sometimes it’s not one room—it’s the whole house. Whether you’ve just bought a fixer-upper or your current home needs a serious update, we can rework your entire space to better suit how you live today.

We’ll help you figure out what stays, what changes, and how to prioritize your investment. From structural updates and layout changes to finishes and fixture selections, our team keeps the process clear and on track—so you're not managing ten different players or chasing down details.

Pittsburgh has no shortage of charm—and no shortage of surprises hiding behind the walls. We’ve spent the last 15+ years remodeling older homes all over the city, from century-old brick houses to post-war ranches.

That means we know how to work with plaster, knob-and-tube, sagging floors, oddball additions, and all the other quirks that come with age. Our goal isn’t to erase the character—it’s to make the home work better for how you live now, without losing what makes it special.

Basements can be a lot more than storage space. Whether you want a guest suite, a media room, a home gym, or a quiet place to work, we’ll help you get the most out of the square footage you already have.

We consider moisture control, ceiling height, egress, lighting, and sound—all the stuff that makes a basement feel finished and comfortable, not just renovated. And, because we handle everything from layout to construction, you don’t need to worry about chasing permits or coordinating trades.

A deck is an extension of your home, not just something tacked on. We design decks that actually work for your lifestyle—multi-levels, built-in seating, space for a grill or fire pit, whatever makes sense for how you entertain or relax.

We use durable materials and think through all the details (like lighting, drainage, or storage), and we make sure it ties into your home both structurally and visually. We also take care of permits and make sure everything is built to code, so you don’t have to second-guess anything down the line.

A home should support every stage of life. Our aging-in-place renovations prioritize accessibility without compromising style.

Thoughtful updates—such as barrier-free showers, wider doorways, and discreet safety enhancements, as well as modern amenities such as home elevators—ensure your home remains as beautiful as it is functional, allowing you to continue living comfortably in the home you love.

Thoughtful architectural design sets the direction for everything that follows. Marvista Design + Build’s architectural services are fully integrated into the design-build process, not treated as a separate handoff.

With a licensed, in-house architect, we evaluate zoning, feasibility, and existing conditions early, grounding ideas in what’s achievable. Our architect collaborates closely with designers and construction leads, ensuring plans reflect real construction insight from the start. This approach creates clear documentation, smoother approvals, and designs that balance function, aesthetics, and longevity—setting your project up for a well-executed, cohesive result.

First-floor remodeling gives your home a fresh, functional layout without sacrificing the neighborhood you love. We listen to what isn’t working and reimagine how your first floor flows, whether that means opening up walls for a more connected living space or adding essentials like a powder room or coat closet for everyday convenience.

We balance structural needs, building codes, and lifestyle goals to create a plan that enhances how you live and entertain. From the initial assessment to thoughtful design and construction, we make sure your first-floor update feels intentional and welcoming.

Closets may be some of the smallest spaces in your home, but they matter every day. Marvista Design + Build transforms reach-in and walk-in closets into thoughtfully organized, custom storage that fits how you live.

With a design-build approach, we plan shelving, hanging space, and cabinetry that work together with your lifestyle and belongings, eliminating clutter and creating efficient storage you’ll appreciate every morning. Each solution is designed with intention—maximizing space, improving flow, and ensuring everything has a place that feels natural and easy to maintain.

Our design-build services bring every phase of your home project together under one roof—architecture, interior design, project management, and construction—so your renovation feels intentional and organized from start to finish. Our integrated team listens first, plans thoughtfully, and manages every step with clarity and care.

Whether you’re updating a single room or transforming an entire home, we guide the process with precision, clear communication, and a commitment to quality that turns your vision into a space that works beautifully for how you live.

A well-designed home comes together when furnishings are considered as part of the overall vision, not an afterthought. Marvista Design + Build helps you select home furnishings that complement the architecture, layout, and finishes of your space.

We source furniture directly from trusted wholesale manufacturers, allowing for better quality, thoughtful customization, and pieces that truly fit the home we’ve designed. From seating and dining tables to custom storage solutions, every selection is guided by proportion, material, and how the space will be used. The result is a cohesive, comfortable home that feels intentional, complete, and tailored to your lifestyle.

Thoughtful window treatments play an important role in how a room looks, feels, and functions. We offer Hunter Douglas window treatments as part of a fully coordinated design approach.

Known for quality craftsmanship, precise light control, and energy-efficient performance, Hunter Douglas products balance style with everyday comfort. From soft, light-diffusing shades to clean-lined rollers and classic wood shutters, selections are made to complement your home’s architecture and interior design. Motorized and smart-home–compatible options add convenience while maintaining a clean, finished look throughout your newly remodeled space.
