"We recently had the pleasure of working with Nimmiya and Navya to revamp our living room, and we couldn't be more thrilled with the outcome. From start to finish, they delivered an exceptional transformation, turning our outdated and challenging space into a modern, stylish, and functional room."
"I would recommend Green Hearth to anyone who might be overwhelmed with the idea of having to design their homes without the necessary confidence or the skills to do something on your own. There is a personal touch that they add, which makes the whole experience reassuring."
"Nimmiya designed our garden escape room recently. Very pleased with her work, very professional and patient. The design we have created seamlessly blends with functionality and innovative approach. Thoughtful use of eco materials and sustainable elements. Overall, a good example of contemporary and environmentally friendly building. Thank you!"
"They designed our living room beautifully, keeping all our requirements in mind while working with the restricted layout of the space. They went above and beyond by also suggesting where to buy the new furniture and lighting, which made the whole process of redecorating so much easier; keeping everything within our suggested budget."
"We were very happy with Nimya’s help with our garage conversion application. She was professional, responsive, and made the process straightforward. Our application was approved, and we would happily recommend her."
"I had a great experience working with Nimmiya and Navya to redo my home through their remote design consultations. They’re creative, professional, and really listen to what you want. The designs were thoughtful and beautifully executed, highly recommend them!"
"They were able to consider how to redesign existing rooms to flow better, incorporate workable storage solutions and how to add a bit of wow to our home. They had such a refreshing and modern approach to design. It’s been wonderful to work with them."
"So grateful for their help, Nimmiya and Navya helped me refresh my space to suit me to a tee!! Really easy to talk to and responsive (sorry again for all the questions!), would highly recommend their services"
"I’m really impressed with the work Greenhearthstudio did on our garden annexe project. They paid close attention to every detail and created designs that matched exactly what I envisioned. Professional, creative, and a pleasure to work with."
"We’ve been house hunting and Nimmiya & Navya have been amazing to work with. They helped us see the potential in different properties and gave us really useful advice about building regulations and future extension possibilities. Their expertise made the whole process so much easier and gave us confidence in our decisions."
