Full Home Interior Design in Hertfordshire and North London

Elevated, cohesive design for your entire home

SARNOVA Interiors offers a complete full home interior design service for clients across Hertfordshire and North London.

Whether renovating a period property, furnishing a newly built home, or redesigning an entire interior, our designer-led approach creates cohesive, elegant spaces that flow beautifully from room to room.

A Complete Interior Design Service for Your Entire Home

Designing a whole home involves more than selecting attractive pieces for individual rooms. It requires a cohesive scheme where colours, materials, textures, and architectural details work together to create a natural flow throughout the property.

By considering each space as part of a wider design vision, we create interiors that feel balanced, layered, and harmonious.

Interior Design for Renovations and New Builds

We work closely with architects, builders, and developers to ensure the interior design integrates seamlessly with the wider construction process.

By collaborating from the early stages of a project, we help coordinate layouts, lighting, joinery, materials, and finishes so that key design decisions are incorporated into the architectural drawings and building works.

This collaborative approach helps avoid costly changes later in the project and ensures that the final interior is both technically achievable and beautifully realised.

Our Serves may include:

- Interior architecture and layout planning

- Lighting and electrical layouts

- Bespoke joinery drawings

- Bathroom and kitchen design

- Procurement and supplier coordination

Creating Cohesive Interiors Across Every Room

Designing a home that feels truly cohesive requires careful planning and attention to detail. Rather than making isolated decisions room by room, we develop a considered design language that runs throughout the entire property. By thoughtfully coordinating colours, materials, lighting, and architectural details, each space connects naturally to the next, creating a home that feels balanced, elegant, and harmonious.

- A Consistent Material Palette

- A Refined Colour Story

- Layered lighting

- Carefully Balanced Textures

- Architectural detailing

Our Full Home Interior Design Process

Our process is inspired by the RIBA Plan of Work, widely used in architecture and construction to manage complex projects.

This allows us to guide clients from the earliest design ideas through construction, installation and final styling, ensuring every detail of the home works together beautifully.

1. Brief and Discovery

Discuss the home, lifestyle, architecture, and client goals.

Understanding Your Home and Vision

In the first stage we take time to understand the property, your lifestyle, and the way you want your home to feel and function. This stage establishes the foundation for the entire design.

Typical Activities include:

Identifying opportunities for improvement

Reviewing architectural drawings

Discussing renovation or building plans

Establishing a design brief

2. Concept Design

This is where we develop the Design Direction. We create an overall design vision for the home, considering colour palettes, materials, furniture style, and the relationship between rooms. Deliverables may include:

Mood boards

Concept imagery

Colour palettes

Preliminary furniture layouts

Design direction

3. Detailed Interior Design

Once the design direction is approved, we develop the detailed drawings and specifications required to bring the project to life. This technical stage ensures that every element of the design can be accurately implemented during construction and installation.  This may include:

Detailed construction drawings

Finish and lighting schedules

Bespoke joinery drawings

Bathroom and kitchen design
