Based on our early survey, these are the categories that matter most to prospective building owner.
The balance of positive, neutral and negative comments. 100 means people spoke about it almost entirely positively.

A middling score could easily be misread as the material wearing poorly. The data says nearly the opposite. Residents reported the hempcrete wall aging without trouble; one venue owner found no sign of aging after a decade of public events. The only reservations were mild, a note that the outer face can take a knock. On upkeep, every remark was positive, and most households have had nothing to do. What pulls the score down is the finish applied over the wall, a separate decision from the material itself. One self-built home used an inexperienced plasterer and paid for it in cracks, by the owner's own admission. Where finishes were chosen and applied well, residents reported no trouble.
Money talk splits cleanly in two, and the split explains the score. Looking back at the point of purchase, residents were matter-of-fact. Some paid a modest premium, one found staged financing a strain, and one named cost as a real barrier to wider adoption. Most remarks are neutral, people stating facts rather than nursing regrets. Looking at what the money bought, every remark was positive. Households described heating bills that barely register, easy indifference to the recent fuel crisis, and in one case a strong energy rating that raised resale value. Everyone who weighed cost against health, ecology, or the chance to build it themselves concluded it was worth it. Only five homes discussed money, so read this one gently.
Not one remark here carried a complaint. Every resident who spoke about comfort spoke warmly, in three ways. Some described bodily ease, a home that is never harsh to be in; one likened walking inside to being wrapped in a blanket. Others pointed to health, including a resident whose severe asthma nearly disappeared after moving in, and others who chose hempcrete for their chemical sensitivities and found real relief. A third group dwelt on the senses: the texture of natural materials, the light, walls that feel alive. A perfect score is rare, so read it precisely. Among the homes that spoke, praise was unanimous. Two homes simply had nothing to say.

“No, not really. Our only concern is the old glass in the door, which could break. The walls might get a little damaged if someone bumps into them, but overall, it's not a major concern for us.”

“People often ask about pests and worry that they might get into the hemp. For me, it's been 10 years, and I've never had any problems with pests.”

“After more than 10 years, we haven't noticed any signs of aging. We've been hosting concerts and welcoming the public throughout that time, and the materials haven't suffered any damage. Neither the lime nor the hemp has shown any deterioration—we haven't had any problems.”

“For me, it's also the reassurance. With concrete, you worry when cracks appear because water can get in and become trapped. With this material, we don't have to panic in the same way. The building naturally moves a little, especially on heavy clay, but we feel comfortable with those small changes.”

“When you have paint or a very smooth surface, it's more difficult to keep the wall looking perfect. With hemp and lime, the texture makes small imperfections less of an issue, and if needed, you can quickly repair it with a lime finish.”

“The special thing about these materials is that they're never perfect—and that's part of their nature. They move, small cracks appear, and for some people that can be difficult to accept. But for me, that's what natural materials do. They change over time.”

“With energy prices rising, we've been fortunate not to feel the impact. Our energy bills have stayed remarkably low, and the system even helps heat our water, which makes a real difference.”

“Our home's energy rating improved significantly—from around an F or G to an A or B. That wasn't just because of the hemp, but also the insulation, solar panels, and air source heat pump. The building inspector was very enthusiastic about the materials and even made special visits to see the project, although there were some challenges in fitting these innovative methods into existing building regulations.”

“One important point is the insulation. In France, when you sell a house, it has to go through an energy performance assessment. If the house isn't well insulated, it loses points, making it more difficult to sell. This insulation performs extremely well, so it actually increases the value of the property.”

“Hempcrete ticked a lot of boxes for us. It was affordable, I could do much of the work myself, and the breathability was a key factor. The insulation has also been excellent, helping regulate the temperature inside the house. Looking back, those were really the things that mattered most to us.”

“You use resources and materials whenever you build something, so we wanted to make choices that felt more responsible. For our garage conversion, we chose more sustainable materials instead of conventional petroleum-based insulation. It wasn't the quickest option—it took two years rather than six months—but it felt like the right decision.”

“Hemp spray is actually priced quite close to conventional materials. The real difference is its performance—you get better temperature regulation, humidity control, and a range of other benefits.”

“From the moment we moved in, we felt a real sense of well-being. The house felt warm, quiet, and comfortable, and because it's built with natural materials and wood, that feeling has only grown stronger over time. It's hard to describe exactly, but living here just keeps feeling better.”

“I was a little worried when I first moved in because I'm someone who's always cold. But the hemplime insulation really surprised me. The house stays comfortable in both summer and winter, and it's made a huge difference in how it feels to live here.”

“For me, the biggest benefit has been the health side of things. I have asthma, and it used to be so severe that I was rushed to the hospital with an asthma attack. One of the reasons we chose hemp was its breathability. I used to go through about one inhaler every month—now I only use one a year. My asthma has almost completely disappeared.”

“As we compared different building materials, we weighed up the pros and cons of each one. Cost and being able to build it ourselves were both important, but what really made the decision was the health aspect. The breathability of the house has made a real difference, and it's worked out really, really well.”

“Caroline's family love being here. The house is always warm in winter and cool in summer without much effort, so it always feels comfortable. We've noticed that really affects people's mood. It's interesting how the environment you're in can make people feel more relaxed and open.”
