This third part of our guide on how to plan a two-story addition is about the design and detail planning phase. You should read the first two parts before you read on.
Part 1 - Dreaming and Defining
Part 2 - Laying the Groundwork
Part 4 - Construction
Part 5 - Completing Your Addition

If you have made it through the first two stages, it's time to turn your dreams into blueprints. We'll explore the purpose of architectural plans, how to develop interior layouts, and why energy-efficient features will save you in the long run.

Architectural Plans

Choose A Design-Build Company

Benefits of Design-Build

Picture a team of experts who can build your dream addition without you having to deal with more than one contractor. That's what a design-build company brings to the table. They combine the power of design and construction, streamlining the process to make sure your project is done smoothly.

Inspect your property while planning to find weak points

Finding a Firm You Can Trust

The team at MI Remodelers can help with any home remodeling project, inside or outside of your home. As a full-service remodeler, we are the best fit for adding a second story to your home. This is due to the fact that we can handle every part of the project.

Blueprint Design

Detailed Blueprints

Architectural plans are the roadmap the crews will follow when it comes time to build. These plans will have all the details those crews need to succeed, from where the walls go to where the plugs are placed.

Key Elements

These plans should act as the manual for your home addition. They will detail the structure of the new floor, pipe and wire layouts, and more. It's all about fine tuning the details to make sure that your new space will meet the needs of your home.

Start with rough sketches of your proposed space

Personale Your Space

Tailor to Your Needs

When it comes to home layouts, one size does not fit all. Your plans should cater to your needs. Most homeowners use a design similar to the first floor's, but you can start from scratch if you'd like. It's your dream; your plans should fit your vision.

Unique Designs

What will set your addition apart? Use this as a chance to add a bonus feature for your new floor. Is it a cozy nook with a built-in shelf for books or a gorgeous bay window? Whatever it is, take the time to add those touches that will truly upgrade the comfort and function of the interior of your home.

Interior Layout

Optimize For Function

Finding More Space

When expanding your space, every square foot counts. Your new floor's layout should make the most of the space. Look for creative storage ideas, ways to create rooms with more than one purpose, and layouts that make the most sense for your daily life.

Ergonomic Concerns

Comfort is key, and so is the flow from room to room. How will you move within your new space? How will you furnish the rooms, and where will room accessories be placed? Taking the time to craft an ergonomic layout can make your life easier.

Aesthetics and Flow

Harmony In Design

You want your new space to feel like a seamless extension of your home, not an alien craft. Choose materials, colors, and styles that complement your current decor to create a balanced flow from floor to floor.

Finding Ideas

Are you looking for inspiration? Browse through interior design trends, Pinterest, and magazines. Gather images and ideas that resonate with your taste to guide your layout choices. You can bring these images when you meet a design professional.

Consider energy saving ways to keep utility bills low with your new space

Energy Efficient Design

Going Sustainable

Eco-Friendly Building Practices

Now more than ever, sustainability matters. Sustainable methods can help the environment and also save you your hard-earned money in the long run. Look into energy-efficient insulation, LED lights that you can dim, and other green building trends.

Green Building Materials

From materials that have been recycled to choosing efficient appliances, there are a ton of ways to lessen the impact new floor will have on the environment. Take a look at bamboo flooring, low VOC paints, and high-efficiency HVAC systems.


As we wrap up, remember that careful architectural planning and design is the key to a successful two-story addition project. Take time with your plans, consider the aesthetics and functionality, prioritize sustainability, and choose your contractor wisely. The result? A beautiful, efficient, and eco-friendly addition that enhances your home and your life. Stay tuned for the next article in this series, where we'll guide you through the construction phase and turn your vision into reality.
