Looking for an experienced commercial interior designer in North London? At The Open Plan, we've been helping businesses transform their commercial spaces for over 20 years, designing inspiring interiors across London, including Crouch End, Stoke Newington, and Central. 

Victorian and Georgian homes are some of the most characterful properties in North London, combining elegant proportions with beautiful period details. While these homes offer incredible charm, many were designed for a very different way of living. At The Open Plan, we have been helping homeowners transform their properties for over twenty years, creating thoughtfully planned kitchen extensions and reimagined living spaces that respect the original architecture while providing everything modern family life requires.Whether you are considering side return extensions, conservatory and orangery extensions, or even attic conversions, careful planning ensures your new spaces feel as though they have always belonged to the home. Our expertise lies in designing extensions that celebrate the property's heritage while introducing light, practicality and contemporary living.

​A successful extension kitchen design is about far more than simply adding extra square metres. It is about improving how your home works every day. We regularly help clients incorporate features such as adding a downstairs toilet, adding a shower room, adding a pantry, and adding a utility room—all carefully integrated into the overall design so that every inch of space is used efficiently without compromising the elegance of the original property.
Many of our clients also want to create a spacious extension family room where cooking, dining and relaxing naturally come together. By carefully considering layout, natural light, storage, materials and architectural detailing, we create rooms that feel welcoming, practical and beautifully connected to both the garden and the original house.

​Every homeowner has a different vision for their property. Some wish to preserve a traditional Victorian feel with decorative mouldings, natural timber and classic cabinetry. Others prefer a refined modern classic aesthetic that combines timeless materials with contemporary functionality. Increasingly, we are also designing clean, sophisticated modern minimalist interiors that sit comfortably alongside original period features. We can demonstrate how each of these approaches can work within your home, allowing you to confidently choose a style that reflects both your property and your lifestyle.
Working throughout Highgate, Muswell Hill, Crouch End, Hampstead, Islington and across North London, we have guided hundreds of homeowners through renovation and extension projects. From the earliest planning stages through to detailed interior design, we help ensure every decision contributes to a cohesive, beautifully considered home.

​​While architects and builders are experts at producing planning drawings and construction plans, they don't usually provide detailed interior design advice. This can sometimes mean that the layout, storage, lighting and overall flow of your new extension or loft conversion isn't the best it could be. By involving an experienced Extension Interior Designer, you can often unlock opportunities that make a significant difference to how your home feels and functions.
​For more than 20 years, The Open Plan has been designing homes throughout North London, helping homeowners transform Victorian, Georgian and 20th-century properties. We regularly work on projects in Muswell Hill, Crouch End, Highgate, Hampstead, Finchley, East Finchley, Winchmore Hill, Southgate, Islington, Camden, Barnet, Haringey and the surrounding areas, creating thoughtful interiors that combine timeless design with modern family living.
