A new beginning, a new story

A new beginning,
a new story

HAPI House is bewitched by colors and made with love and passion for creating beautiful homes and exclusive interior spaces. Always in deep gratitude of the living memories we all carry and the future we will dream of together.

Chapter one:
The revelation of color

Revelations can come unexpectedly or intentionally. From a heartfelt desire to change direction in life, a need to start having more fun, a wish to build a new nest. 

We guide our clients with a philosophy of letting go and appreciating the stories that surround us. It’s a way of approaching life with revelations of color. When design and decor is rooted in our personal stories, we get the chance to start living in the moment authentically with a true appreciation of life.

HAPI House is a way of living and a rebirth of Christine’s approach to interior design. We choose to decorate with a focus on atmosphere, vibrations, and vitality.


There’s no formula for interior design, and we encourage the individuality and variation of each home. Because perfection is not the ideal. We have the choice of making interior design about more than just pretty things. With a philosophy of appreciating the beauty of the imperfect, we have set out on a path to create meaningful and personal spaces for everyone to indulge in togetherness, music, literature, spirituality, and art.

For more than two decades, Christine Callsen has built a business guided by her exquisite taste, intuition, and her talent for designing personal interior projects down to the very last detail all over Europe.

Hapi inside

Inspiration is the ignition of an idea. It’s the sudden revelation of a direction and vibration in designing and creating a project. Art, music, literature, and mindfulness are true inspirations in everything we do and create.

We’re happy to share our music and book list that ignites and serves as inspiration… even on a blue day. Welcome inside Hapi House.

We encourage our clients to greet the unexpected, find their playful selves and believe in the philosophy that colors, shapes, and art can be our guiding stars in life.
