The Story Behind the Renovation
This open-plan living, dining, and kitchen interior design project in Stanmore was created to bring together functionality, comfort, and contemporary style within a modern family home. The brief focused on creating a seamless connection between the key living areas while maintaining a sense of warmth and individuality throughout the space. As an experienced interior design company, we developed a design that enhances everyday living while supporting entertaining and social interaction.
We designed the layout around a natural flow between the lounge, dining area, and kitchen, ensuring each zone feels connected yet distinct. Soft neutral furnishings are complemented by rich timber finishes and muted green cabinetry, creating a sophisticated palette that feels both inviting and timeless. A central kitchen island serves as the focal point of the space, while a carefully planned lighting design scheme introduces balance, atmosphere, and visual interest. Feature walls incorporating stone finishes, timber detailing, and integrated lighting add depth and architectural character throughout the interior.
The design combines practical family living with refined aesthetics, resulting in a home that feels spacious, cohesive, and welcoming. Drawing on the expertise of leading luxury interior designers in London and skilled specialists from our kitchen renovation company team, the project reflects the quality and attention to detail associated with premier interior designers London.
Planning around existing structures to control costs
A major technical challenge was re-routing the kitchen waste pipes and power cabling to the new central island across a solid concrete sub-floor, without raising the floor levels or creating step transitions.
We carefully channeled a 1:40 gradient fall into the concrete sub-floor. This allows waste water from the sink and dishwasher on the island to drain efficiently while keeping the kitchen floor completely flat and level.
Managing Open-Plan Odors & Sightlines
The Problem: Open-plan layouts run the risk of cooking odors migrating from the kitchen into soft lounge sofas and curtains. Additionally, traditional ceiling-hung cooker hoods block visual sightlines across the dining area, making the open layout feel divided.
The Solution: We installed a high-output downdraft extractor flush with the induction hob on the central island. This pulls cooking steam and odors down at the pan surface, venting them out under the floor plate, leaving overhead sightlines completely open.
The Client's Challenges
Transforming this open-plan Stanmore residence required addressing several complex kitchen and spatial challenges:
- Open-plan cooking odors: Cooking steam and odors migrating from the hob into soft lounge drapes and furnishings.
- Sub-floor island plumbing: Channelling waste pipes and water lines to the central island across solid concrete floors.
- Appliance noise migration: Loud dishwasher and disposal noise disrupting quiet reading or television viewing in the lounge.
- Overhead sightline blocks: Standard suspended cooker hoods blocking open views across the dining and living spaces.
- Unbalanced work triangle: Fitting the sink, oven, and fridge into a comfortable layout without island pathway blocks.

Solution We specified high-performance, integrated appliances running below 38dB and lined cabinetry cavities with soundproofing felt to absorb structural noise.
Atmospheric & Lighting Solutions
Lighting Challenge Splitting Cooking and Lounge Light Circuits
To transition the open-plan room from bright meal preparation to cozy relaxation, we split the lighting circuits. Recessed task spotlights illuminate kitchen prep counters, while warm suspended pendants over the island and dimmable LEDs behind wall panels create a relaxed dining mood.
Mistakes We Prevented
Designing open-plan family kitchen spaces requires preventing structural and operational errors:
Prevented Damp Soft Furnishings
We prevented food odors and grease from settling on lounge couches by using a high-output, flush downdraft extractor next to the hobs.
Prevented Slow Drainage Blockages
We prevented slow island drain clearance by cutting a precise gradient fall directly into the concrete sub-floor for all waste lines.
Prevented Loud Appliance Echoes
We prevented noisy open-plan conditions by selecting integrated appliances running below 38dB and using sound-absorbing felt backing.
Prevented Blocked Island Pathways
We prevented blocked walkways by testing spatial clearances around the island on CAD plans, ensuring clear routes even when cabinet doors are open.
Prevented Flat Visual Aesthetics
We prevented flat walls by blending stone marble textures, warm timber slatted details, and muted green cabinetry across all zones.
Why We Made These Design Decisions
Every material and layout choice was selected to support active family living and structural efficiency.
Why Flush Downdraft Extractor?
Installing a downdraft extractor pulls cooking odors down at the pan surface, keeping overhead sightlines clear across dining and living areas.
Why Muted Green Cabinetry?
Selecting muted green cabinetry brings a sophisticated, timeless color into the kitchen, connecting it beautifully with garden views.
Why Choose a Central Island?
Building a central kitchen island creates a multi-use family hub for cooking, breakfast dining, and homework while separating prep paths.
Why Mix Wood and Marble Textures?
Combining vertical wood panels and stone marble textures draws lines across the room, making open-plan zones feel connected yet distinct.
Why Layer Lighting Circuits?
Using separate lighting circuits allows the room to shift from bright meal prep spotlights to warm, decorative dining and lounge ambient light.

Behind the Scenes: Coordinating Sub-Floor Drainage
To safely route water pipes to the central island sink without raising the kitchen floor level, we channeled a 1:40 gradient fall directly into the concrete sub-floor before the main tiles were laid.
By coordinating our layout design with the plumbing contractors early on, we kept plumbing lines hidden away and ensured the island waste water drains quickly and reliably.
Kitchen Renovation FAQs
How can you prevent cooking odors from traveling into open-plan living areas?
We install hob-integrated downdraft extractors flush with the island countertop. This pulls steam and grease down directly at the pan level, venting them out under the floor plate before they can migrate.
Can you install a sink and dishwasher on a central island with a concrete floor?
Yes. We channel a precise gradient fall directly into the concrete sub-floor before laying the tiles. This allows waste water to drain quickly and safely without needing to raise the room's floor levels.
How do you prevent noisy kitchen appliances from disrupting adjacent lounge areas?
We specify integrated appliances running below 38dB and line cabinetry cavities with soundproofing felt backing. This absorbs structural noise, keeping the open-plan room quiet.
Why are downdraft extractors better than ceiling-hung hoods in open-plan designs?
Flush downdraft hobs pull steam down directly, leaving overhead sightlines clear. Ceiling-hung hoods can block open views across dining areas and make the open-plan room feel visually divided.
Can you integrate utility and wiring systems into custom TV wall panels?
Yes. Custom wood panels and marble features can be built to integrate media wiring and power outlets. We include hidden access points in our designs to ensure utilities remain accessible for maintenance.
