Luxury Interior Designers
A beautifully constructed basement or property extension deserves an interior that matches its quality. Advantage Basements & Renovations offers a comprehensive interior design service for private residential clients and property managers across London, creating spaces that are as considered in their aesthetics as they are in their construction.
Our interior designers work closely with you from the earliest stages of your project, ensuring the design of your space – its proportions, lighting, materials and flow – is integrated into the build from the start rather than added as an afterthought. The result is an interior that feels cohesive, purposeful and unmistakably premium.
“Nothing was ever too much trouble and the
finish is exemplary.”

We specialise in high-end residential interiors for London's most distinguished properties.

From spatial planning and materials selection to bespoke joinery, lighting design and the specification of fixtures and fittings, we manage every element of your interior with the same attention to detail we apply to the construction itself. We work with the finest British and European suppliers, sourcing materials and products that reflect the quality of your property.
Our approach is always collaborative. We listen carefully to your preferences, lifestyle and vision before developing design concepts that feel personal and distinctive. Every scheme we create is unique – there are no off-the-shelf designs, only spaces designed specifically for you.
Architectural & Planning Services
Seamlessly Integrated Interior Design with Your Construction Project
One of the key advantages of choosing Advantage Basements & Renovations for your interior design is the seamless integration with your construction project. Our design-and-build teams work within the same organisation, meaning your interior designer and project manager are in constant communication throughout the build. This eliminates the delays and coordination challenges that frequently arise when interior design is commissioned separately.
From the positioning of building services to the specification of wall finishes and flooring, every design decision is made with full knowledge of the construction context. The outcome is a project delivered with greater efficiency, fewer surprises and a finished space that fully realises your vision.
Interior Design Services for London Basement Spaces
Basement interiors present unique design opportunities and challenges. Maximising the sense of light and space in an underground environment requires specialist expertise – in ceiling heights, lighting schemes, material selection and the careful planning of room layouts to create spaces that feel open and welcoming rather than enclosed.
Our interior designers are highly experienced in creating basement interiors that feel luxurious, light-filled and comfortable. Whether your basement will become a home cinema, spa, gymnasium, wine cellar or additional living accommodation, we design environments that are perfectly suited to their purpose and a pleasure to inhabit.

Coordination with our construction team to ensure the design intent is maintained throughout the build
We work closely with you from the earliest design stages, ensuring your basement interior is integrated into the construction from the start rather than applied as an afterthought.
Can you work with my own interior designer or architect?
2
Absolutely. We offer a comprehensive in-house design service, but we are equally comfortable working alongside your chosen interior designer or architect.
Our construction team regularly collaborates with external design professionals, approaching these relationships with professionalism and respect for the designer's vision. Clear communication and coordination between design and construction teams is essential to successful outcomes, and our project managers facilitate this throughout the build. Whether you already have a designer in place or would like to use our in-house interior design service, we are flexible and focused on delivering the best possible result.
How do you ensure the interior design services remain within my budget?
3
Budget management begins at the design stage. Our interior designers work within the financial parameters you establish at the beginning, making specification choices that deliver the quality and aesthetic you desire without exceeding the budget.
We provide transparent cost guidance throughout the design process – advising on the relative cost implications of different materials, finishes and fixtures – so you can make informed decisions about where to invest and where to economise. Our integrated design and construction service means there are no surprises: the designs we create are buildable within your stated budget, and our project managers maintain cost control throughout construction.
