A 3-season sunroom addition brings your backyard closer, creating a light-filled space for most of the year.

Ideal for entertaining guests, dining al fresco without bugs, or enjoying afternoon naps, this addition maximizes enjoyment in Carmel homes. In many of our projects, a sunroom’s expansive windows and skylights create a bright, inviting atmosphere.

Some homeowners opt for durable tile or vinyl flooring to withstand seasonal changes, while some residents incorporate cozy seating and custom blinds for year-round comfort.

Features like ceiling fans, insulated glass, and built-in shelving for plants or decor enhance the versatility, making this perfect for both family gatherings and quiet relaxation.

In Carmel’s suburban setting, sunrooms often serve as reading nooks or play areas, blending indoor comfort with outdoor views.

This stunning screened-in porch addition, modeled after a lakeside cottage, is a dream for homeowners seeking charm and functionality.

In Meridian-Kessler, we designed a porch featuring rustic beams, a butler’s pantry, and built-in benches, thereby reducing the need for trips to the central kitchen during gatherings.

The screened design keeps bugs out while providing an extra family room or entertainment space.

Homeowners add weather-resistant furniture and ceiling fans for comfort, while other Indianapolis area clients incorporate outdoor heaters for cooler evenings.

Skylights or glass panels enhance natural light, and durable screens ensure longevity.

This addition seamlessly blends indoor coziness with outdoor serenity, making it ideal for hosting barbecues or relaxing with a book in central Indiana’s picturesque neighborhoods.

3. Multi-Level Porch Addition

For outdoor enthusiasts in Carmel, a multi-level porch addition offers versatile living spaces. This addition includes two vertically stacked porches and an undercover hot tub, accessible from the master bedroom. 

Composite decking ensures durability against Indiana’s weather, and integrated LED lighting creates ambiance for evening use. Railings with modern designs or built-in planters add style, making this addition perfect for year-round outdoor enjoyment. In Carmel’s family-oriented communities, multi-level porches serve as hubs for social gatherings or private retreats.

If you enjoy outdoor living, why force yourself to walk up or down to the main level to relax? This multi-level porch can be your own private deck!

4. Master Bedroom Suite Addition

Escape to a luxurious primary bedroom suite that rivals a country estate.

In Zionsville, an 8’x10’ master suite addition transformed a modest space into a serene retreat with a walk-in closet, en-suite bathroom with dual vanities, and a private seating area.

Homeowners often incorporate large windows or sliding glass doors to flood the space with light. Some clients choose hardwood floors to match the historic aesthetic.

Features like built-in storage, a cozy fireplace, or a soaking tub elevate comfort, creating a spa-like haven. These suites often feature private balconies, providing a tranquil space for enjoying morning coffee or evening relaxation.

This breathtaking master bedroom suite looks like it belongs in a country estate! You too can kick back like landed gentry in your home in the suburbs. 

5. Garage and Outdoor Kitchen Addition



Looks can be deceiving! From the front, this garage addition appears to be an ordinary detached garage. But walk around to the back side and you are in an outdoor kitchen and entertainment area!

Complete with a bar, fire pit, and everything you need to entertain, this is a wonderful way to expand your living space outdoors!

One of our Carmel projects features a bar, fire pit, seating, and stainless steel appliances, making it an ideal space for hosting.

Some Zionsville homeowners add pergolas or retractable awnings for shade, while some Meridian-Kessler clients incorporate stone countertops for a timeless look.

Built-in grills, refrigerators, and storage cabinets enhance functionality, and weather-resistant materials ensure durability. This addition expands living space outdoors, blending practicality with style for seamless entertaining in the vibrant communities of central Indiana.

6. Second-Story Home Addition

Is your bungalow feeling too tight? A second-story addition, like the one pictured, accommodates a full master bedroom suite and home office.

In Meridian-Kessler, this freed up main-level space to expand a cramped kitchen, dining area, and living room.

Some Carmel homeowners add dormer windows for architectural charm and natural light, while some Zionsville clients include built-in storage or skylights to maximize space.

Reinforced framing ensures structural integrity, and insulation improves energy efficiency. This addition transforms compact homes into spacious retreats, ideal for growing families or remote workers in central Indiana’s suburban settings.

Designing Your Home Addition

A home addition in Carmel requires thoughtful planning to align with your lifestyle. Whether you seek a sunroom for outdoor enjoyment or a primary suite for luxury, our team at Worthington Design & Remodeling collaborates with you to create a space that enhances both functionality and aesthetics.

Matching Your Home’s Style

In Carmel, additions seamlessly blend modern luxury with suburban charm, utilizing materials such as brick, glass, or cedar to complement the existing structures. Meridian-Kessler homes preserve their historic character with wood trim, classic moldings, and arched windows, ensuring that additions feel seamless. Zionsville’s farmhouse-style homes feature rustic elements, such as shiplap or reclaimed wood accents. Our designs incorporate architectural details such as gabled roofs or stone cladding to ensure your addition enhances your home’s overall appeal, reflecting the unique character of your community.

Maximizing Your Home’s Space and Value

Additions maximize space without sacrificing yard size. In small Carmel lots, vertical additions like second-story suites add room efficiently, preserving outdoor areas for gardening or play. Some Zionsville homeowners benefit from multi-level porches that expand outdoor living, while some Meridian-Kessler clients use garage additions for entertaining spaces. These additions boost resale value by appealing to buyers seeking spacious, move-in-ready homes. Features like energy-efficient windows or sustainable materials add long-term value, ensuring your investment endures.

Customization for Your Needs

Every family has unique needs. Carmel entertainers prioritize screened porches with butler’s pantries for seamless hosting, while some families need kid-friendly spaces like sunrooms with durable flooring. Some homeowners often request master suites with spa-like bathrooms featuring heated floors or oversized showers.

Our consultation process assesses your lifestyle, from daily routines to long-term goals, ensuring your addition is tailored to your specific needs, whether for relaxation, work, or social gatherings.
