Felix Lewis Architects is an architecture and interior design studio working across Maidstone, Kent and the South East of England. We specialise in house extensions, residential renovations, bespoke new-build homes and barn conversions, creating thoughtful, design-led spaces that respond to the character of each property and the way our clients live.

Whether you are planning a contemporary kitchen extension, renovating a traditional Kentish home, converting a rural barn or building a new house, our architectural and interior design services bring creativity, practicality and attention to detail to every project.

From initial feasibility studies and planning applications through to detailed architectural drawings and interior design, we help homeowners transform their properties with carefully considered design.

House Extensions in Maidstone

A well-designed house extension can completely change how a home looks, feels and functions. We design residential extensions in Maidstone and the surrounding Kent countryside, from modest side and rear extensions to substantial contemporary additions.

Our architectural approach considers natural light, spatial planning, materials and the relationship between the house and garden. Whether extending a Victorian terrace, a period cottage or a modern family home, we aim to create spaces that feel connected to the existing building while introducing something new.

Our extension projects include open-plan kitchen and dining spaces, two-storey extensions, glazed extensions and whole-house remodelling. See our full architectural serviecs and selected projects here.

Home Renovations & Refurbishments

We provide architectural and interior design services for home renovations and property refurbishments in Maidstone, helping homeowners improve existing spaces while retaining the character of their properties. From renovating traditional Kentish houses to completely reconfiguring modern homes, our work combines practical improvements with thoughtful architectural design.

We consider everything from internal layouts and natural lighting to bespoke joinery, kitchens, bathrooms and material finishes. By bringing architecture and interior design together, we create homes that feel cohesive, functional and personal.

New Build Homes in Maidstone & Kent

Designing a new home offers the opportunity to create something entirely suited to your lifestyle, site and surroundings. Our residential work offers bespoke new-build houses across Maidstone and Kent, developing architectural designs that balance contemporary living, sustainability and the local landscape.

From early concept designs and planning applications to technical drawings and construction detailing, we help clients develop distinctive, design-led homes with an emphasis on quality, longevity and carefully selected materials.

Barn Conversions & Rural Architecture

Kent's rural landscape is home to a wide variety of traditional agricultural buildings, including timber-framed barns and historic farm buildings.

We work on barn conversions in Maidstone and the surrounding countryside, helping transform agricultural buildings into contemporary homes while respecting their original character.

Our approach combines the retention of historic materials and architectural features with modern interventions, natural light and carefully planned interiors.

We also provide architectural services for rural property renovations, farmhouse extensions and the sensitive adaptation of traditional buildings. You can check out our Cedar Barn project on our architectural page.

Listed Buildings & Heritage Renovations

Maidstone and the surrounding Kent villages contain many historic properties, from traditional cottages and Georgian houses to listed farmhouses and converted agricultural buildings. We have experience working with listed buildings and heritage properties, developing sensitive architectural proposals that balance modern living with the preservation of historic character.

Our services include listed building alterations, heritage renovations, extensions to period homes and assistance with planning applications and Listed Building Consent. We believe that contemporary design and historic architecture can work beautifully together, creating considered interventions that respect the past while improving how buildings are used today.
