    My experience with Jam by Hedayat has been outstanding. Jam managed a full refurbishment of my central London flat, handling the concept design, selection of contractor, furniture purchasing and overall project management supervision. As I live abroad, their turn key approach was essential to the success of the project. Hedayat and Marcia are both extremely experienced professionals who go out of their way to ensure the end results meet the client's expectations. Being hit by the coronavirus half way through the project was difficult but the Jam team met the challenges head-on with perseverance and good humour. I highly recommend Jam by Hedayat for anyone looking for a team to manage their interior design requirements, they are a first rate design studio.

    Jam by Hedayat Ltd. were hired to do design and procurement services for a Community/Sales Centre at our West Carclaze Garden Village project in Cornwall. The project was a demanding one as it needed to achieve multiple design and functional objectives (be a showcase for the project as a whole, eco/sustainability criteria, use of local materials, artists and artisans etc) all to be delivered within a limited budget and time program. Jam represented by Hedayat and Marcia did a great job and were a pleasure to work with. They demonstrated a try understanding for our brief and enormous creativity and flexibility with respect to how to deliver it. They are consummate professionals in terms of respecting commitments and time schedules. I have no hesitation in whole heartedly recommending Jam by Hedayat.

    Hedayat and her senior designer have just completed the full drawings for my penthouse. I have really enjoyed working with both of them. They grasped the aesthetic I was looking for from the get go and did a brilliant job. Their understanding of materiality and how I want to use my space to create serene understated personal spaces mixed with playful joyful more public spaces has made the whole process joyful. When working on something so personal, it is important that the client feels ownership of finished product and they have achieved that with me. I am very excited to start work on my place. They seemed to understand my taste and delivered exactly what I want.

    Working with Jam By Hedayat for our beach house was an amazing experience. I'm sometimes sceptical working with interior designers especially for homes, the homes sometimes come out looking like the designer’s home and not yours. Working with Jam and Hedayat was the opposite experience. Hedayat brought out exactly our dreams into the house. Which turned out to be our summer Haven. I can’t recommend JAM By Hedayat enough! so much talent and a beautiful working relationship

    Jam by Hedayat is a very professional company. I’ve dealt with the owner on two projects abroad. My Battersea apartment was the third project and the first in London. They’re punctual, honest, creative and deal with the best quality of labour in the UK
  • "Hedayat was perfect for us. I didn't want to redo the whole house, but felt I needed to change the atmosphere and mood in some of the rooms. Within a couple of short hours Heddy had drawn up a scheme which meant changing some of the colours and placement of furniture, replacing one or two items and re-organising things in a way that made everything fresh stylish and more modern without compromising the integrity of what we had before. Not only was it a great pleasure to do this with so little effort on my part, it was incredibly efficient and cost effective. I would highly recommend Heddy and her unswerving eye."

  • "Hedayat took on the job of doing the interior design of my new home. I have never come across such dedication! The meticulous attention to detail, the efforts expended to help me stick to my budget, and the passion that went into the drawings as well as the sourcing of fabric, wallpapers, furniture, and accessories was tremendous. I am only saddened by the fact that the project is now done... I have to find new ways of working with Jam Space. I unreservedly recommend them!"
