A realistic guide to design, approvals and restaurant fit-out
Opening a restaurant in London is an exciting step — but it is also one of the most complex interior projects a business owner can undertake. Many first-time restaurateurs imagine the process as a design exercise: choosing finishes, creating a brand atmosphere and installing a kitchen.
In reality, opening a restaurant involves architecture, engineering systems, regulatory approvals, construction coordination and specialist hospitality equipment.
Understanding the full process early can save months of delays and prevent costly surprises later.
For many restaurant owners, the journey begins with a single question:
What actually happens between signing the lease and opening night?
1. Choosing the Right Space
Before design even begins, the most important decision is the space itself.
Not every commercial unit can easily become a restaurant. Many locations require significant technical upgrades before they can support a professional kitchen and hospitality operation.
Key factors include:
-gas supply capacity
-electrical power availability
-extraction and ventilation routes
-drainage infrastructure
-structural limitations
-landlord restrictions
Older buildings in London often require additional investigations such as drainage surveys or asbestos surveys before construction can begin.
Many restaurant owners choose to consult a design & build team before signing the lease to assess whether a property is technically viable.
2. Concept Design and Layout Planning
Once the space is confirmed, the design process begins.
This stage defines the character of the restaurant and how the space will function operationally.
Typical work at this stage includes:
interior concept developmentlayout planning for dining and circulationcommercial kitchen layout coordinationpreliminary bar and service designearly lighting strategyinitial material direction
A well-designed layout ensures the restaurant works efficiently for both staff and guests.
At this stage, the design team also begins identifying technical challenges that could affect the project later.
3. Landlord Approvals and Licence to Alter
Most commercial restaurant spaces in London require landlord approval before construction can begin. This process typically involves submitting concept drawings and technical documentation to the landlord's surveyor.
These submissions may include:
-concept layouts
-shopfront proposals
-ventilation and odour strategy
-structural interventions
-kitchen location and services requirements
Once approved, the landlord issues a Licence to Alter, allowing the tenant to proceed with construction.
This stage alone can take several weeks if not managed carefully.
4. Planning Permission and Local Authority Approvals
Depending on the project, additional permissions may be required.
Typical planning considerations include:
external signage and advertising consents
hopfront alterations
extraction systems visible from outside
listed building considerations
changes to building use class
Restaurant projects often require planning submissions and building control coordination simultaneously.
5. Technical Design and Engineering Coordination
Once approvals are underway, the project moves into technical design. This stage translates the concept into a buildable project.
-Technical work typically includes:
-structural engineering coordination
-MEP systems (mechanical, electrical and plumbing)
-gas systems and safety controls
-ventilation and extraction design
-fire suppression systems
-lighting design and electrical distribution
Restaurant kitchens require particularly careful planning because of their ventilation, gas and fire safety requirements. At this stage, specialist consultants may also prepare:
-fire consultation and fire risk assessment
-building control documentation
-extraction system drawings
-commercial kitchen technical layouts
6. Construction and Fit-Out
Once approvals are secured and technical drawings are complete, construction begins.
Restaurant construction typically includes:
structural works where required
ventilation and extraction system installation
gas supply and safety interlock systems
electrical installation and three-phase power
drainage and plumbing systems
flooring and wall finishes
ceiling construction and lighting installation
custom joinery such as bars and seating
commercial kitchen installation
shopfront and signage installation
Because restaurants combine engineering systems with interior architecture, the coordination of trades is critical.This is why many projects are delivered through a design & build model, where design and construction are managed by one responsible team.
7. Furniture, Equipment and Final Installation
As construction nears completion, the project moves into its final installation phase.
This stage includes:
furniture and seating installation
bar equipment installation
commercial kitchen appliances
custom lighting fixtures
decorative elements and finishing details
By this point, the restaurant begins to resemble the original concept design.
8. Certification and Handover
Before opening, the restaurant must pass a series of safety and compliance checks.
These often include:
electrical certification
gas certification
fire alarm commissioning
ventilation testing
building control inspection
Once these are completed, the project reaches handover. At this stage, the restaurant is fully operational. The owner simply brings their staff, their menu and begins preparing for opening day.
Why Many Restaurants Use Design & Build
The process described above involves dozens of consultants, approvals and construction trades.
Without clear coordination, delays and cost overruns are common.
A design & build approach integrates the entire process under one responsibility — from concept design through construction and final handover.
Kapeti Interior Architecture delivers restaurant interiors through this integrated model, allowing restaurant owners to focus on their business while the project is managed behind the scenes.
Final Thoughts
Opening a restaurant in London is a complex process, but with the right team and planning it becomes manageable.
The key is understanding that a successful restaurant project is not simply about decoration — it is about coordinating architecture, engineering systems, regulatory approvals and construction into one coherent programme.
When those elements come together properly, the result is a restaurant ready to open, operate and welcome its first guests.
