Luxury House Extension in Carshalton | High-End Residential Builders Covering Sevenoaks

We recently completed a luxury split-level house extension in Carshalton, delivering a full turnkey, high-end residential build finished to an exceptional standard. As experienced builders covering Sevenoaks and the surrounding areas, we specialise in architect-led extensions, premium refurbishments, and bespoke homes designed and built for modern luxury living.

This project showcases our ability to deliver complex, design-led construction with precision, combining structural alterations, advanced building systems, and high-end finishes throughout.

Architect-Led Build with Full Contract Administration

This project was delivered under a fully architect-led design, with a dedicated contract administrator managing the project from start to completion. This ensured:

• Full compliance with drawings and specifications
• Continuous quality control at every stage

This approach is essential for high-end residential construction in areas such as Sevenoaks, where attention to detail and build quality are critical.

• High-end herringbone flooring installed throughout the ground floor

• All elements delivered ready for immediate occupation

This level of service ensures a seamless experience for our clients and a consistently high-quality finish across the entire property.

Project Overview – High-End Residential Extension

This was a complete transformation of the ground floor and external living areas, designed to enhance space, light, and flow while introducing modern luxury features expected in high-value homes across Sevenoaks and the South East.

Key Features & Specification

Split-Level House Extension

A bespoke split-level extension was constructed to create a dynamic, open-plan layout. This design maximises natural light and enhances the connection between internal spaces.

Aluminium Windows & Bifold Doors

All rear windows were upgraded to high-performance aluminium systems, alongside large-format aluminium bifold doors. This not only improves thermal efficiency but creates a seamless transition between the home and garden.

Rear Elevation Rendering

The rear of the property was fully rendered to achieve a clean, contemporary finish, significantly enhancing the external appearance of the home.

Underfloor Heating Installation

A fully integrated underfloor heating system was installed across the ground floor, providing efficient, even heat distribution and a premium living environment.

New Boiler & Air Conditioning System

We installed a modern energy-efficient boiler alongside full air conditioning throughout the property, ensuring year-round climate control and comfort.

Ground Floor Bedroom with En-Suite

A new ground floor bedroom with a high-spec en-suite bathroom was constructed, ideal for flexible living or guest accommodation.

Open-Plan Living Area Upgrade

The main living space was completely reconfigured to create a bright, open-plan environment suited to modern living.

Luxury Kitchen Relocation & Installation

The kitchen was relocated and redesigned, featuring bespoke cabinetry and premium granite worktops, creating a central feature space within the home.

Bespoke Outdoor Living & Landscaping

• The external works were designed to complement the internal renovation and provide a luxury outdoor living experience:
• Fully levelled and landscaped lawn
• Premium porcelain paving throughout
• Bespoke masonry outdoor cooking and BBQ area
• Motorised pergola for year-round usability

This creates a seamless indoor-outdoor lifestyle, a key feature in high-end residential properties in Sevenoaks.
