🏡 Another Custom Home Coming Together!

This home from Custom Building Systems combines classic design with features that make it feel right at home. From the two-story layout and attached garage to the covered front porch, every detail helps create a welcoming place to call home.

The neutral exterior, contrasting roofline, and multiple gables give this home plenty of curb appeal, while the covered porch offers a great spot to relax and enjoy the outdoors.

✨ One of the best parts of modular construction is the ability to customize a home to fit your vision, from the floorplan to the finishing details.

🏠 Thinking about adding more living space in Maryland?

New legislation is putting more focus on Accessory Dwelling Units (ADUs).

Maryland House Bill 1466 and Senate Bill 891 established a statewide framework to promote and encourage ADU development. An ADU can be an attached or detached living space, or an independent unit created within an existing home.

ADUs can offer homeowners additional flexibility, whether the space is intended for family, guests, aging parents, or other housing needs.

With local jurisdictions working toward ADU regulations by October 1, 2026, this is a good time to learn about the possibilities and your local requirements.

Modular construction may be a great option to consider. A modular ADU can be constructed in a controlled plant environment and then transported to the property for installation.

📍 **Have questions about modular options for an ADU? Contact us today!

🏡 Choosing a floorplan? Start with these 7 questions.

The right floorplan isn’t just about what you need today, it should also make sense for how you plan to live in your home for years to come.

Before choosing a layout, ask yourself:

1️⃣ How many bedrooms will your family need in five years?
2️⃣ Do you prefer one-story or two-story living?
3️⃣ Would first-floor laundry make everyday life easier?
4️⃣ Do you need a dedicated space for working from home?
5️⃣ How much storage space do you really need?
6️⃣ Will you regularly have overnight guests?
7️⃣ Are you looking for a home that can adapt as your needs change?

Taking time to think through these questions can help you narrow down your options and choose a floorplan that works for the way you actually live.
