Welcome to K Space Interiors.

K Space Interiors is a London-based interior design studio specialising in residential renovations and full refurbishments across London.

Led by BIID-registered designer Krystyna Martin-Dominguez, the studio is known for delivering homes that are as intelligently resolved as they are visually compelling. Each project is approached with a clear understanding of both design and construction — balancing layout, proportion, materials, colour and bespoke joinery to create spaces that feel effortless.

Clients come to K Space when they want to get it right. Often they have lived in their homes for years, recognising the potential but unable to translate it into a clear direction. What sets the studio apart is the ability to bring clarity early — to define the right decisions from the outset and guide the project with confidence through to completion.

Krystyna works closely with builders and specialist trades, moving seamlessly between concept, detail and site. She is known for her decisiveness, clarity and ability to think on her feet — a steady presence throughout complex projects.

The process is structured and precise, allowing each design to be developed in direct response to the client and the home.

Based in London, working across London and internationally.

Our Design Philosophy.

Design at K Space Interiors begins with understanding the home.

Before anything is added, we look at how the space works — its layout, flow, light and the structure that supports it. This foundation-led approach ensures that decisions are made in the right order, creating a strong base for everything that follows.

From there, the design is developed with precision. Materials, colour and bespoke elements are introduced carefully, so that each layer feels natural rather than applied.

The aim is not to impose a style, but to arrive at a solution that feels resolved — a home that works as well as it looks.

Our Collaborative Process.

Each project follows a clear and structured process.

We begin by understanding the property and defining direction early, removing uncertainty and allowing the project to move forward with confidence. Decisions are made in sequence — starting with layout and spatial planning, followed by services, and finally the refinement of materials and finishes.

We work closely with builders and specialists throughout, ensuring continuity between design intent and what is delivered on site. This allows for informed decisions, efficient problem-solving and a smooth progression from concept to completion.

The process is collaborative, but never uncertain — clients are guided with clarity at every stage.

Sustainability & Long-Term Thinking.

Sustainability at K Space Interiors is approached through longevity.

We focus on creating homes that are built to last — through considered layouts, durable materials and well-planned infrastructure. Every decision is made with long-term performance in mind, rather than short-term effect.

Materials are selected for how they age, spaces are designed for how they will be used, and each element contributes to a home that feels grounded and enduring.

Sustainability, in this sense, is not an added layer, but a natural outcome of designing well.

Why Choose Us.

K Space Interiors combines design clarity with a strong understanding of how homes are built.

With over 15 years of experience, the studio is particularly valued on complex renovation projects where clear thinking and confident decision-making are essential.

Clients choose K Space for its ability to bring structure to the process while maintaining a high level of design. Each project is approached individually, guided by a defined method but never reduced to a formula.

From rethinking layouts to designing bespoke joinery and refining materials, every element is considered in relation to how the home will function and feel over time.

The result is not simply a designed interior, but a home that is complete — visually, practically and technically.

Are We a Good Fit?

K Space Interiors is best suited to clients who want to approach their renovation properly.

Most come to us after realising that good ideas are not enough. What they need is clarity — how to move forward, what to prioritise, and how to avoid getting it wrong.

Our work is collaborative, but directed. We shape the process, make decisions in the right order and ensure the project progresses with clarity from the outset.

We work best with clients who:

  • are ready to invest in doing things well

  • value design as much as execution

  • are open to a structured, well-managed process

  • trust professional judgement

In return, we deliver homes that feel effortless — because they have been properly thought through.

If this approach resonates, we would be pleased to work with you.

This grounding in both design and construction allows her to move with ease between concept and site, ensuring that ideas translate into something that can be built well.

She is known for her clarity, decisiveness and ability to quickly understand both the home and the client. Her role is not to present options endlessly, but to define direction and move the project forward with confidence.
