This project expanded an existing home with a new two-story addition, a larger front porch, a new side entry, and several roof and exterior modifications. The existing house was not large enough to accommodate the homeowners’ needs, so the design focused on increasing usable space while preserving the scale and character of the original residence. Rather than making the addition feel like a separate structure, the new spaces, facade, roof forms, and exterior details were developed to read as a natural continuation of the existing home.

 

At the front of the house, the existing small porch was removed and replaced with a larger L-shaped porch extending toward the left side of the property. The expanded porch provides access from both the front entry and the backyard side, creating more flexibility in how the house is approached and connected to the site. Several existing windows along the affected wall were removed to accommodate the new porch configuration. The existing front door was also replaced with a new side entry, reflecting the homeowners’ preference to approach the house from the side rather than directly from the front facade. The new entry and porch were designed together to create a more functional arrival sequence while giving the exterior a stronger presence.

 

One of the most significant changes to the existing house was made at the upper level above the living room. The existing entry and living area features an open-to-below condition that continues visually to the second floor. A wide shed dormer was introduced above this space, bringing additional natural light into the living room and creating a greater sense of volume beneath the roof. Beyond its impact on the interior, the dormer also helps establish a clearer connection between the existing second floor and the new addition, improving circulation between the two areas.

 

The new addition is attached directly to the existing home and extends across two levels. The entire lower level of the addition is dedicated to a garage, with access provided from both the front and backyard sides. This creates convenient vehicle access from either direction and allows the garage to function as an integral part of the expanded home rather than as a detached structure. No separate stair was introduced within the addition; instead, the second floor is accessed directly from the existing home's second floor, allowing the new space to remain closely connected to the original circulation.

 

At the second floor, the addition was designed with its ridge aligned with the ridge of the existing house. Matching the roof elevations helped maintain a consistent overall silhouette and allowed the new volume to sit comfortably beside the existing structure. A large shed dormer was added to the addition as well, increasing the amount of usable interior area beneath the roof while bringing additional natural light into the space. The matching dormer strategy creates a visual relationship between the existing and new portions of the house, helping the two volumes read as part of the same architectural composition.

 

The second-floor addition provides approximately 340 square feet of new space planned as an office. By accessing this room directly from the existing second floor, the addition becomes a natural extension of the home's upper-level living space rather than an isolated new room. The increased floor area, combined with the new dormer and coordinated roof plane, allows the office to feel more generous and functional without significantly increasing the apparent height of the addition.

 

Throughout the project, the existing structure and new construction were considered together. The placement of new openings, windows, doors, and exterior elements was coordinated with the existing fenestration so that the expanded house would maintain a consistent rhythm. New siding, trim, roof edges, and other exterior details were selected and arranged to complement the existing home rather than creating a contrasting addition. The relationship between the existing and new roof forms was especially important, with the aligned ridge, matching dormers, and coordinated roof plane helping establish continuity across the expanded house.

 

The project also improves the home's relationship with the surrounding site. With access from both the front and rear, the expanded porch and garage create clearer connections between the house and its exterior spaces. The new side entry provides a more practical daily entrance, while the larger porch offers additional outdoor space and creates a stronger transition between the interior and the surrounding yard.

 

As a result, the project provides a larger and more functional home while maintaining the character and proportions of the existing residence. The new addition was designed to feel like a natural part of the existing house, creating a cohesive overall appearance.

Thinking about a similar project?

Let’s talk about how we can work together.

A 3D architectural rendering of a two-story detached accessory dwelling unit (DADU) located behind an existing brick single-family home. The DADU features a combination of white horizontal siding and board-and-batten cladding, a gable roof, and a large projecting volume with tall multi-pane windows overlooking the backyard. An elevated deck connects the second floor of the main house to the upper level of the DADU, while a screened porch provides access to the lower-level music studio. Several people and a dog are shown enjoying the backyard beneath a bright, partly cloudy sky surrounded by trees.

Frequently Asked Questions

What was the goal of this project?

The goal was to expand the existing home to provide more living space and functionality while preserving its original character. The new addition and updated exterior elements were designed to feel like a natural extension of the existing house

How did you approach the design process?

We focused on integrating the new addition with the existing home, while improving space, natural light, and circulation. The design also used matching dormers and aligned roof forms to create a cohesive connection between the existing house and the new addition.

What challenges did you face?

One of the main challenges was integrating the new two-story addition with the existing home while maintaining its original character. We also had to balance the added space with the scale of the existing house and create a cohesive connection between the two structures.
