Fixing the 'Tall Forehead' House: How to Modernize a Flat, Boxy Exterior

The Dilemma

A homeowner recently asked:

We just bought a house with a flat, grayish-green brick exterior that looks dull compared to our neighbors, and we need ideas to make it look modern without adding cheap shutters.

The Scenario

You just bought a house in a great neighborhood, but while your neighbors have charming red brick homes with classic proportions, yours looks like a dull, greenish-gray cardboard box. The front of the house is entirely flat, and there is a massive expanse of blank brick above the top windows.

This is a textbook example of The Tall Forehead Syndrome. You have a large expanse of unarticulated vertical facade that creates a disproportionate, empty architectural face. To make matters worse, the landscaping is actively fighting the architecture. The foundation shrubs have been sheared into tight, rigid spheres, which is a classic maintenance failure known as The Meatball Syndrome. Instead of softening the severe lines of the house, these rigid spheres just reinforce the stiffness of the property, making it look like a fortress.

The Trap

When homeowners stare at a massive, blank wall, their first instinct is usually to start gluing things to it. The most common mistake is adding decorative shutters to the windows in an attempt to fill the empty space.

Shutters are the absolute wrong move if your goal is modernizing a flat facade. This building has a stark, almost industrial geometry to it. Tacking on shutters will just make it look like a confused colonial replica. Unless shutters are sized wide enough to actually close over the glass, they just look like stuck-on plastic ears that cheapen the entire exterior.

The Solution (Deep Dive)

To fix a flat, boxy exterior, you do not need more clutter. You need contrast, visual weight, and soft engineering. Here is how you actually modernize a dull facade.

1. Embrace High-Contrast Paint That greenish-gray paint is causing the house to fade into the background. To modernize a boxy shape, you need to make the geometry pop. A deep, saturated charcoal or a stark, crisp white will make the flat lines look intentional and architectural rather than unfinished. If you are worried about painting brick, remember that That ‘Ugly’ 70s Brown Brick Isn’t the Problem (Your Trim Is). Sometimes, simply painting the trim and roofline a high-contrast color is enough to frame the house properly.

2. Thicken the Window Sashes Instead of adding fake shutters, give the existing windows more visual weight. Paint the window sashes black or a very dark charcoal. This draws the eye to the glass and makes the windows feel heavier and more substantial without fighting the clean, modern lines of the house.

3. Use Soft Engineering in the Landscape Right now, those sheared "meatball" shrubs are mirroring the rigid squares of the house. You need to break up the geometry with movement. Rip out those tight balls and plant loose, flowing drifts of ornamental grasses or tiered perennials that move with the wind. A sweeping mass of native switchgrass or fountain grass will instantly make the house feel less severe. Always check the USDA Plant Hardiness Map to ensure you select grasses that will thrive in your specific winter climate.

4. Add Architectural Lighting A flat facade disappears at night. You need to introduce shadows and depth artificially. Install up-lights at the base of the brick or modern sconces flanking the entryway. Grazing the brick with light from below highlights the subtle texture of the masonry and breaks up the massive vertical void.

The Diagnostic and Visualizing Safety Net

Before you commit to a dark charcoal paint job or rip out all your foundation shrubs, you need to see how these changes will interact with your specific roofline and sun exposure. You can upload a photo to our Exterior Design App to test a dark slate paint color and overlay loose, naturalistic planting styles. It acts as a safety net, allowing you to see exactly how different textures and high-contrast colors will break up that big brick face before you spend a dime at the nursery or the paint store.
