We appointed Mia Karlsson Interior Design to advise us on planning the interior of an extension and also to refresh and update a number of other rooms. We worked closely with their Senior Designer Tarryn who brought her imaginative design ideas and professionalism to the job. Tarryn always listened closely to our ideas and concerns and responded sensitively. In this way we were able to achieve a great overall result. She also worked well with our architect and other professionals. As part of their service MKID were able to order products on our behalf and recommend suppliers and craftsmen who they

I have worked with Mia on my personal home interior projects for 7 years now and in all that time I have found her and her team to be efficient, friendly, highly competent and most importantly very stylish. I love everything that she has helped me with. She does not abandon near the end of the project, but continues through until every last details is correct. Mia is a pleasure to work with.

We engaged Mia Karlsson Interior Design when we remodelled an area comprising a conservatory, a laundry and bathroom. It was a confined space and presented design challenges. The result was a highly functional space, attractively presented. Overall, it was a professional job and we are very pleased with the outcome.

We used Mias service for redecorating our house, including refitting two bathrooms and designing a new walk-in wardrobe. We are extremely happy with the result. This is the first time we have used an interior designer and I am certain that we could not have achieved anything close to this result on our own so we would definitely go down this path again in the future. Mia is also fun to work with and sensitive to our tastes. She was aware of our budget limitations so made sure we focused our expenditure on things where it would make the biggest difference. Where we purchased a few extravagant

I cannot speak highly enough of the job Mia did on our house. As background my wife and I had just purchased our dream home where we wanted to raise a family and live for the next 20-30yrs. Our only issue was that we had very different taste and ideas as to how to decorate the different rooms. In stepped Mia who sat with us repeatedly at the weekend, over a period of three months, patiently going through reams of wall paper, books of carpet fabrics and countless books of furniture from which we could then choose what we liked and which she would put together for our approval.
