For homes with small kitchens and a warren of ground floor rooms, kitchen diner extensions are one of the best options for opening up your space and creating a room that can be put to good use. It’s a practical and affordable project that makes a great alternative to the expense and upheaval of moving house, and it allows homeowners to add considerable value to your property at the same time. Of all the home improvements you may consider, a kitchen dining room extension is the most popular and offers the best returns. Now all you need to do is choose the right kitchen diner extension design.
Designing a Small Kitchen Diner Extension
Adding just a few metres onto a small kitchen can transform a dark and pokey space into a light-filled, usable space for entertaining or family. While every property is different, and terraced properties have their own challenges, there’s a surprising amount that you can achieve with the right construction partner.
One of the most effective options for these properties includes rear extensions into the garden space, often completed with a stylish deck area and wide glass sliding doors to extend the space out into the garden for outdoor dining and entertainment. This can be combined with removing walls and changing the floor plan to make the space open and free-flowing. Many extensions of this type include large skylights and panels of glazing in the roof of the extension, drawing in as much natural light as possible.
With smaller extensions, a great design is critical to make the best use of your space. With the right approach and innovative design ideas, you can create a beautiful kitchen, dining and entertainment space, and even include a small home office space, wine storage, and other luxury extras.
Larger Kitchen Diner Extensions
If you have a larger property or an end-of-terrace house, you have even more options at your fingertips. Your extension can be as large as planning permissions and the budget allows, giving you the ability to add new rooms and functionality while opening up your space.
Popular options for these homes include wraparound extensions, side and rear extensions, and even combination rear or side extensions with second-floor loft extensions. With the right kitchen diner extension design, your home can be reinvented to create large, family-friendly eating, entertainment, and gathering space, as well as adding useful extras like a ground floor WC, laundry room, or home office space.
As with the smaller extensions, design is key to making the space flow well, be fully functional for your needs, and use the space as cleverly as possible. Whether you want a bold, modern-industrial design or a traditional extension that seamlessly fits into your existing home while preserving natural light and character, having a design specialist will ensure your extension pays off.

A New Lease on Family Life in Norwood
Sometimes all a home needs to reach its full potential is a rear extension. In this West Norwood home, a 2.5m x 6.2m full-width rear extension with a fully glazed rear wall updates this home for modern life. Completed with sensitivity to the original style of the home, the extension is designed to include Critall-style doors and herringbone wooden flooring to seamlessly expand the home and settle into the building’s architecture. The pitched roof of the extension creates a feeling of spaciousness inside the combined living and dining area, and the tasteful skylights mean that adding length to the space improves natural light into the room.

An old, poorly designed extension can damage the value and use of a property the same way a new, well-designed extension can improve it! In this Ruislip home, the old extension simply wasn’t working. Replacing it with a modern, flat-roofed 3m x 7m full-width rear extension delivered the open, light-filled contemporary space that every homeowner dreams of. The feeling of spaciousness is exceptional, creating large dining, relaxing and cooking zones that seamlessly work together for entertaining and family life.

Light-filled Living in Tooting
In a mid-terrace property, you can often feel closed in by homes on either side. But as this rear extension completed for this Tooting home shows, the dream of open breathing space can be made real. By having a rear wall that fully opens into the garden, the size of your living space is opened to huge proportions, allowing you to adapt the space for entertaining, family living, or simply enjoying the garden. The large triangular glazing in the roof’s pitch along with the skylights means even more light is added to the room, creating a true outdoor feel and letting in the light in any weather.
