Luxury renovation company in London. Whole houses and apartments, priced open book, under one contract.
What clients in Mayfair, Knightsbridge, Belgravia and Chelsea now ask for has shifted. A refined interior is still the starting point. The brief usually also covers how the house performs. That is not a trend any more. It is the standard brief.
What sustainable luxury means
It means choosing materials, systems and construction methods. These cut the environmental cost of the work. The standard of the craftsmanship does not drop. The two are not in tension as often as people expect.
The five elements
- The building envelope. Triple glazing, insulation and heat recovery ventilation. This comes first, because every system downstream is sized against it.
- Controls. Automated lighting, heating and cooling. The house is then not heating rooms nobody is in.
- Natural and reclaimed materials. Reclaimed oak, limestone and similar finishes. These carry character and far less embodied carbon than new.
- Solar and heat pumps. Discreet panels, battery storage and a heat pump lower the emissions. They lower the running cost too.
- Water. Greywater recycling, rainwater harvesting and efficient fittings, all of which can be hidden.
Why it matters in prime postcodes
In Chelsea and Belgravia, most of the stock is listed. Much of it is in a conservation area. That means the performance has to be improved. The building must look the same. This is a design problem rather than a shopping list. Done properly it also protects the value of the house as buyer expectations move.
Quiet luxury meets sustainability
The current design language is understated. Warm neutrals, soft textures and joinery made for the room. Limewash finishes, low-VOC paints and responsibly sourced timber happen to suit that look. That is why the two arrived together rather than by coincidence.
How we run it
Sustainability sits inside the design at NU Projects rather than beside it. We source the materials. Our MEP team designs the systems. The planning route for a listed or conservation-area property is handled too. It sits in the same contract.
