Transforming a 2-Bedroom Bungalow into a 4-Bedroom Chalet Home – Kent Countryside

Reimagining rural living through intelligent design, structural expertise, and high-performance construction.

Project Overview Over a 10-month period, we transformed a modest two-bedroom bungalow in the Kent countryside into a spacious, high-specification four-bedroom chalet-style family home. Appointed as principal contractor, we managed every stage, from site set-up and demolition to the complete build and final handover, delivering a turnkey solution tailored to our client’s lifestyle and the rural setting. Client Brief The client requested a contemporary family home with generous open-plan living spaces and future-proof sustainable technologies. The design involved enlarging the existing footprint and extending vertically with a structural steel framework to accommodate three additional bedrooms, including a luxurious master suite with en-suite, walk-in storage, and a private balcony overlooking the countryside. Ground Floor & Interior Design The ground floor was reimagined as a bright, open-plan living, kitchen, and dining area forming the heart of the home. Carefully considered details maximise natural light and flow, complemented by stone flooring and seamless access to the landscaped garden. A dedicated home office and separate snug provide flexibility for modern family life.

Sustainable & High-Performance Features As part of the full build, we installed an energy-efficient air source heat pump, underfloor heating across the ground floor, a mechanical ventilation with heat recovery (MVHR) system, and air conditioning. These systems ensure exceptional comfort, improved air quality, and reduced energy consumption, aligning the property with modern sustainability standards.

External Works & Landscaping The project included extensive landscaping: A sweeping gravel driveway for a striking first impression and ample parking. A separate double garage, matching the main house’s architectural style. A natural stone patio, partly covered by an oak pergola, connecting indoor and outdoor spaces, perfect for entertaining. Outcome Through meticulous planning, coordination with Building Control, and high-quality craftsmanship, we delivered a modern, energy-efficient chalet home. The transformation demonstrates our capability to manage complex structural alterations, integrate high-performance building services, and execute extensive external works, providing a home that combines long-term value, sustainability, and lifestyle functionality.

Week 1: Site Setup & Controlled Demolition The existing bungalow roof was carefully removed under the protection of newly erected scaffolding, allowing works to commence safely and efficiently. Temporary power and water supplies were installed to support the clients, who remained living on site in two static caravans for the duration of the project. Careful planning at this stage ensured minimal disruption while maintaining progress on programme. The majority of the external walls were scheduled for removal, retaining just two elevations in order to maximise the site’s potential and square off the new building footprint. Demolition and foundation works were carried out using compact machinery capable of operating safely within the confines of the scaffolding, enabling precision and efficiency during this critical early phase.

Week 4: Foundations & Structural Preparation After four weeks of intensive groundwork, the Bobcat E10 and Slane tracked 1-tonne barrow had certainly earned their keep, playing a key role in progressing the site efficiently within restricted access conditions. The new foundations were completed, reaching depths of up to 1.8 metres in areas where required. Two substantial concrete pads were also formed to support the central structural steelwork, which will act as the spine of the new building—transferring loads from the roof structure safely down to ground level and forming the backbone of the chalet extension.

Week 12: Structural Frame & First Fix Coordination Progress at this stage was significant. The structural steelwork supporting the ground floor was fully installed, along with the Pozi joists forming the intermediate floor structure. The next phase of steelwork for the roof had also been accurately measured and prepared for fabrication. Underground drainage was completed, together with ductwork for incoming services. Initial first-fix electrical and plumbing works were underway, including provisions for the new kitchen island. Precision setting out was critical at this point to avoid service clashes and ensure structural alignment. All walls and key elements were carefully marked before installing the underfloor heating pipework and manifold system over the new insulation, damp proof membrane, and vapour barriers. Throughout this phase, we continued close coordination with Building Control, ensuring inspections were carried out at the appropriate milestones and that all works complied fully with current regulations.

Week 18: First Floor Structure & Roof Formation With the intermediate floor complete, construction of the timber-framed first floor began, carefully built around the newly installed structural steelwork to form the chalet’s upper level. Due to site access constraints, the cranked steel ridge beam was fabricated in two sections and spliced on site. Each section was carefully manoeuvred into position using a combination of the ever-reliable Unimog and Genie lifts, ensuring safe and precise installation. Flitch beams were installed either side of the new dormers to provide additional structural strength, while triple rafters were formed to trim the Velux openings in preparation for the remaining roof timbers. The main roof structure was then cut and pitched on site, and studwork was constructed to define the layout of the new inset balcony. To maximise ceiling height within the first-floor rooms, timber collars were positioned as tightly to the steel ridge as engineering tolerances would allow delivering the generous vaulted ceilings the client had envisioned.

Week 22: Roofing & Finishing Touches The new slate roof was installed under scaffolding, ensuring precise alignment and quality workmanship. Fascias, soffits, and trims were completed, and Velux windows were carefully fitted, integrating seamlessly with the roof structure. These works established the final protective shell of the home, allowing internal and external finishing stages to progress.

Week 26: External Works & Window Installation With the roof complete, the scaffolding was removed and doors and windows were fitted, creating secure and airtight openings. The team also prepared the sub-base for the new patio, marking the start of the external finishing and landscaping phase.

Week 32: Interior Fit-Out & Landscaping Completion Exterior cladding and the patio were finished, while inside, plastering, flooring, and kitchen installation were completed. Trades worked in coordination to finalise services and finishes, bringing the home close to handover and ready for the client’s move-in.
