E-Interior design


It all started with my belief...

Everyone deserves to live in a well-designed home that will bring new life to us.

I've worked as an interior designer for the past 13 years, in the meantime, I assured myself that home design is what I genuinely enjoy doing and what I’m best at. I love my job, and that's great, but what can I do to make it better?

After all things considered, I've reached the conclusion that is E-INTERIOR DESIGN. I create unique design concepts individually because we all have different lifestyles and tastes and it can be done affordably and comfortably.

I'm super excited to launch new E-INTERIOR DESIGN services! I hope it will bring us more opportunities to elevate the pleasure of life.

How it works

(room makeover)



Your Needs & Style Check

Once you purchase the service and fill out a request form, I'll follow up within 1-2 business day with the welcome package which includes the detailed questionnaire, guidance for measuring and photographing your room by email. 

Please complete and send it back to me in 1 week.


Design Concept & Shop List

As soon as I receive all the information from you, design work begins. Based on your info I'll create 2 concept boards to check the blueprint and pick your favorite. Then, the detailed design will be prepared. It usually takes 2-3weeks to finish the final design package.

We'll have two round revisions to make any changes before you approve the final design. I'm happy to receive your feedback and discuss with you about it. The final package includes online shop list.


Comfortable Order (optional)

When you receive your final design package, it’s time to go shopping and make your dream space!

If you are too busy to do it yourself, let me shop for you. You don't need to order everything, but choose only what you want to buy. I'll deal with overall orders to finish it more comfortable and relaxed.

Room Makeover

“I really enjoyed the e-design service offered by Sungeun of lifestyle Si. Sungeun has a keen eye for detail and color. She created a wonderful design for my salon based on my preferences. I’m now really happy with my Eclectic Glam Book Salon, and I highly recommend Sungeun and her e-design service!”

Room Fresh-Up

“We asked Sungeun to update our reading nook and dining room. She suggested lovely ideas to upgrade our apartment right away. Now, we’re coming back to her to get another advice for the wardrobe in our guest room. We recommend Sungeun if you have any kind of interior dilemmas.”
