What is Modern Coastal?

Modern coastal design blends the airy, laid-back feel of traditional beach houses with sleek, minimalist modern design elements. It's characterised by a calm colour palette, natural textures, and an uncluttered aesthetic that prioritises light and space. The goal is to create a living room that feels both expansive and intimate, drawing inspiration from the textures and colours of coastal locations.

1. A Warm, Neutral Palette with Accent Colours

The colour scheme is critical in setting the tone for a modern coastal living room. Start with a base of warm neutrals such as off-white, soft grey, and beige to create a light, airy backdrop. Accents in shades of blue, along with seafoam green and sandy taupe can add a dynamic yet subtle touch of colour that mirrors the coastal environment.

2. Timber Furniture

A beautiful timber coffee table or entertainment unit can act as a focal point in your living room. We recommend opting for pieces with a raw, natural finish or you could even go for a lightly whitewashed timber to enhance the coastal vibe. The texture and natural imperfections of the wood lend a touch of rustic charm to the room, anchoring the lighter tones of your colour palette.

3. Light Flooring

Flooring choices play a pivotal role in creating the modern coastal look. Light-coloured hardwood floors set a fresh and inviting foundation for the space. Both light flooring options, and even walls, help to reflect natural light around the room, enhancing the overall sense of space and openness.

4. Organic Shapes

Incorporating furniture with organic shapes helps to soften the often harsh lines of modern design. Items like an irregularly shaped coffee table, mirror or even a curvaceous armchair can introduce fluidity and movement into your living room, making the space more inviting and comfortable.

5. Linen Sofas

When it comes to sofas (or even armchairs), linen in a neutral tone is your go-to. Linen is not only timeless but also highly durable and perfect for a laid-back, beachy feel. It offers a casual texture that becomes more appealing over time and is ideal for relaxing after a long day. This piece of furniture will truly make your space feel like a holiday at home.

6. Bright, Airy Spaces

Modern coastal living rooms thrive on a strong connection to the outdoors. Maximise this aspect with large windows, glass sliding doors, or French doors that open out to an alfresco or garden. This design strategy not only brings in more natural light but also extends the living space physically and visually to the outside. 

Tip: If you’re not looking to make structural changes, why not optimise that light you currently have? We recommend opting for sheer curtains to add to the overall coastal feel of the space without blocking any natural light.

7. Unique Décor

Decor items in a coastal living room should evoke a sense of calm and sophistication. Use vases that mimic the textures of the ocean and add cushions with soft tones. You could even opt for cushions with large strips or patterns to create interest within your space. Artworks that incorporate abstract interpretations of the ocean or coastline can add a modern artistic touch and serve as conversation starters.

8. Jute Rugs

Underfoot, a jute rug can add texture and warmth to the living room. Its natural fibres and earthy tones complement the wooden elements and neutral palette of the room, while also being sturdy enough to withstand high foot traffic, aligning with the practical aspects of coastal living.

9. Artistic Lighting

Lighting fixtures are often the focus of the room, and in a modern coastal living room, they should both illuminate and intrigue. Consider pendant lights with organic textures such as woven rattan or raw ceramic-like texture to add both light and artistic elements to the space.

Lamps can be just as important in a living room as pendant lights. Discover the living room lamps we’re currently loving.

10. Modern Functional Features

To maintain the sleekness of modern design, integrate contemporary technology in unobtrusive ways. Wall-mounted smart TVs, integrated sound systems, and modern climate controls can enhance the functionality of the living room without disrupting its coastal style.

Frequently Asked Questions

Can you mix coastal and modern decor?

Absolutely! Mixing coastal and modern decor is at the heart of creating a modern coastal living room. This style blends the relaxed, natural elements of coastal decor—like soft, sandy palettes and wooden textures—with the sleek, minimalistic features of modern design, such as clean lines and high-functionality furnishings. To achieve a harmonious look, focus on maintaining a neutral colour base and choose modern furniture with simple, elegant lines. Incorporate coastal accents subtly through textiles, artwork, and decor to keep the space feeling cohesive and intentionally styled.

How do I make my living room look modern?

To give your living room a modern look, focus on simplicity and functionality. Start with a neutral colour palette, favouring shades of white, grey, and black, and then introduce colour through art or a single accent wall if desired. Choose furniture with clean lines and exposed legs to create a sense of space and lightness. Incorporate sleek, contemporary materials such as glass, metal, and glossy finishes. Keep the space clutter-free with smart storage solutions and minimal decor items. Modern design is all about space and light, so ensure there is plenty of both to make your living room look fresh and contemporary.

What colours are used in coastal design?

Coastal design is known for its light, breezy colour palette inspired by the natural environment of the beach and ocean. The most common colours include various shades of blue, from navy to turquoise, reflecting the water. These are often complemented with whites, creams, and sandy beiges, mimicking the beach. Accents of greens can also be incorporated to mirror the coastal flora. The overall effect is a clean, refreshing look that echoes the serenity of seaside living. For a modern twist, integrate these colours subtly alongside a dominant neutral base to keep the space feeling open and airy.

How do I make my house feel coastal?

Creating a coastal feel in your home involves incorporating elements that evoke the light, airy, and relaxed vibe of the beach. Start by using a colour palette dominated by whites, soft neutrals, and various shades of blue and green to mirror the natural seaside environment. Flooring should be light and natural, such as pale timber or bamboo, to enhance the breezy feel. Use plenty of natural materials throughout your decor, including linen textiles, rattan furniture, and jute rugs. Open up your living spaces to as much natural light as possible with large windows or skylights, and consider sheer, flowing curtains to soften the sunlight. Decorative accents like seashells, driftwood, and nautical-themed pieces can be used sparingly to add character without overwhelming the space. To truly capture the essence of coastal living, focus on creating a relaxed layout that encourages comfort and ease, promoting a holiday-like atmosphere year-round.
