The Space: A 20×20 Living Room

The Challenge: This spacious square living room has to incorporate lots of windows and doors, an opening to the kitchen, a wall of built-in shelves, and a corner fireplace.

This is a common large living room design found in many family homes and suburban houses. But while a large living space means more design possibilities, it can sometimes be trickier to land on a living room layout. With three walls lined with windows, doorways, and built-in shelving, coming up with a functional living room furniture arrangement is more challenging. Also, you’ll want to make sure your layout suits your lifestyle and how you want to use the room.

Keep scrolling for three different takes on furniture layout for this 20×20 living room, and get our tips for decorating a large space in your own home. From a layout optimized for TV watching to a design focused on formal entertaining, each of these living room layout ideas offer practical and stylish takeaways you’ll be able to bring into your own home.

Layout Idea #1: A Living Room For TV Viewing

For a large living room layout where family entertaining and TV viewing is the main purpose, anchoring the space with a comfy seating area is key.

In this living room furniture layout, we optimized the design for function with seating in the middle, a dedicated TV space off to the side, a fireplace corner that’s inviting, and leaving lots of walking room all around. The result is a cozy living room with a fireplace and a TV layout that’s practical and maximizes every square inch of space while still feeling open and airy.

Frame your seating area with a sectional. To ground the living room with a main seating area, a large corner sectional sofa is a great anchor piece. It adds ample seating and faces the room’s entrance and welcomes people in. This also leaves room for armchairs that offer extra seating. Together, the sectional and chairs form a U shape that’s perfect for family TV watching.

Be sure not to block your windows. With walls of windows, use them to the fullest for natural light. Keeping the windows unobstructed with curtains or lighting in front of them allows light to stream in throughout the space, making the living room feel even more airy and bright.

Zone your space with layered rugs. In a large living room, creating zones for different purposes will help with the flow. The layered rugs under the seating area help frame the main lounging spot here and set it apart from the TV wall and fireplace. Additionally, the two rugs placed on top of each other also provide extra padding underfoot that protects the floors.

Set up a functional TV wall. In this living room, the TV is large and takes up an entire wall off to the side to maximize viewing. Because the TV is so big, it’s comfortably in view from every seat on the sectional sofa as well as the armchairs, which can also be turned to face the TV.

To round out the TV wall, we brought in a media console that’s proportionally larger than the TV to balance out the look of the screen and anchor and ‘zone’ the entire wall space.

Layout Idea #2: A Living Room With An Office

With homes working harder to be multipurpose these days, a living room layout that includes a home office is a gamechanger. In this living room furniture layout, the space serves multiple functions, including a work area, but maintains an open and cohesive design style that makes the space appear as one large room instead of an office and a living room that feel separate.

Try a formal sofa arrangement. The heart of this living room is a cozy conversational seating area with two facing sofas. It’s a slightly more formal furniture layout, but the style of the sofas help ease things up for a casual look and feel. It’s the perfect sofa arrangement for an approachable living room layout that’s equal parts conversation-friendly and laid-back.

Leave lots of walking room. The biggest challenge with a large space is making it feel cozy while still keeping the layout spacious and open. To create a sense of comfort while allowing for lots of walking room and flow, the seating area is minimally furnished with an open-base coffee table and moveable ottomans, which zone the space without making it feel closed off.

Float furniture to define your space. Floating furniture, aka. arranging large pieces away from walls, is a great trick to add function as well as zone a living room. Here, the console table behind the sofa is at once a display surface, a catchall, and a room divider that anchors and separates the living space from the entrance.

Incorporate a home office corner.

There’s no better space to carve out a home office than a large open living room. The office space here is off to the side and transforms the empty wall into a practical work corner. It’s also perfectly positioned near the built-in shelves, which also makes practical sense.

To ensure the office feels like a part of the living room, a neutral cowhide rug extends out and connects the desk and seating area. Additionally, the light-wood desk and chair have a versatile look that matches the casual feel of the family-friendly sofas, coffee table, and ottomans.

Carve Out A Comfy Nook. One of the best ways to make use of a living room with a corner fireplace is to create a comfy seating area next to the hearth. The upholstered bench in front of the fireplace becomes an instant reading nook and lounging corner for cozying up.

To play up this fireplace corner even more, we added a moveable bar cart to make it the perfect drinks station for entertaining and serving cocktails.

Spotlight unique pieces. With a grand piano, give it the spotlight it deserves in a large living room. We placed the piano in a corner of the room and paired it with a large round rug to set it apart as the main focus. Surrounded by the windows, it’s the perfect spot for entertaining guests with some music or for kids to practice while parents relax in the seating area nearby.

Go for big upholstered pieces. 

A formal living room layout looks best with upholstered pieces that are sumptuous, large-scale, and provide major comfort. The wingback chairs here not only ground the seating area with a lot of presence, they’re also the perfect tall seats to add a sense of warmth to the overall room alongside the corner fireplace.

Make for an intimate seating area. 

With large-scale furniture and upholstery in a large space, grouping the pieces closely together in one area is the best way to instantly create an inviting look and feel.

The seating area here is centered between the fireplace and built-in shelving, which makes it an instant cozy spot for lounging, curling up near the fireplace, and all kinds of conversation and entertaining.
