The Brief
Our clients in Southampton were drawn to the less-is-more philosophy of Scandinavian and Japanese design. They wanted a kitchen extension that embodied calm — clean surfaces, hidden storage, warm neutral tones and absolutely no visual clutter. Every appliance, every utensil, every spice jar would have its designated place behind handleless doors. The result should feel like a sanctuary from the busy world outside.
Our Design Approach
We designed a 28m² extension with a simple, restrained aesthetic. The flat roof sits low and unobtrusive, with a single large rooflight positioned to illuminate the main work area. The rear wall features a minimal-frame sliding door — a single large panel that glides silently on a concealed track, opening to a zen-inspired courtyard garden designed in harmony with the kitchen.
The kitchen itself is a masterclass in concealed design. Full-height handleless cabinetry in a warm greige tone houses everything — appliances are integrated behind matching doors, a pull-out pantry hides dry goods, and a pocket door conceals a utility area. When everything is closed, the kitchen reads as a series of calm, uninterrupted surfaces.
Planning and Approvals
This compact extension qualified under Permitted Development rights. We obtained a Lawful Development Certificate from Southampton City Council and Building Regulations approval covering structural works, insulation, ventilation and drainage.
Key Design Features
- Handleless cabinetry: Push-to-open doors in warm greige creating seamless, uninterrupted surfaces
- Concealed LED lighting: Strip lighting under wall units and within shelving creating a warm ambient glow
- Integrated appliances: Every appliance hidden behind matching cabinet doors
- Pull-out pantry: Full-height pull-out larder maximising storage in a compact footprint
- Zen courtyard: Minimalist garden design extending the calm aesthetic outdoors
The Result
This Southampton extension achieves exactly what our clients wanted: a sense of calm. With everything stored away and surfaces kept clear, the kitchen feels spacious and serene regardless of what is happening elsewhere in the house. The warm neutral palette and concealed lighting create an atmosphere that shifts from energising during the day to relaxing in the evening. It proves that minimalism, done well, is anything but cold.
Cost and Package Guidance
For a 28m² modern extension in Southampton, the biggest budget variables are usually structural steelwork, glazing specification, drainage changes, foundation conditions and final kitchen, bathroom or joinery choices. Hampshire Build's fixed-fee design packages give homeowners clear design-cost certainty before construction begins, with Essential, Pre-Build and Premium options depending on how much technical documentation and contractor support is needed. The design fee is separate from builder costs, planning fees, Building Control fees and any third-party specialist reports, so clients can make informed decisions without confusing design work with the wider construction budget.
Local Context and Practical Considerations
Projects in Southampton benefit from early attention to neighbouring amenity, overlooking, daylight, access for builders and material choices that sit comfortably with the existing street scene. On this project, the drawings needed to communicate not only the look of the extension but also how it would work technically: roof drainage, insulation build-ups, structural openings, floor levels and practical circulation through the home. That level of detail helps planning officers, Building Control and builders understand the proposal clearly, reducing avoidable questions and giving the homeowner a stronger basis for the next stage of their extension journey.
