Home & Interior Design Trends To Watch Out For In 2026
What We’re Seeing Now
In the basement of a £38 million Kensington townhouse completed last spring, there is no gym. Instead, our client—a technology founder who sold his company and relocated from San Francisco—built a cryotherapy chamber flanked by a Finnish sauna, a counter‑current pool and a meditation room whose acoustics were engineered with the same care given to Abbey Road’s recording studios. Upstairs, his kitchen is smaller than most people would expect for a house of this scale. This is not an oversight. It is a choice.
After three decades advising UHNW clients in prime Central London and the English countryside, we have learned that what people really want from their homes bears little resemblance to what estate agents believe they want. The trends shaping 2026 reflect a recalibration of how wealth is lived privately, how space is used when no one is watching, and how homes are being designed to solve problems that did not exist a generation ago. These are not predictions pulled from thin air; they are patterns we see now, in active projects, driven by clients who understand that a great house is infrastructure for a better life.
Below we outline the design themes we expect to define 2026, supported by recent data and project examples.
Wellness Suites: From Amenity to Architecture
The “basement gym” of the 1990s is dead. In its place are fully fledged wellness suites with cryo chambers, aromatherapy saunas, hydrotherapy pools and recovery rooms. This shift is driven by three forces:
- London’s restrictive plot sizes – to gain space without altering the street façade,
homeowners excavate, often adding multiple basement levels. - A generational focus on longevity – clients in their 40s and 50s are investing as much in their bodies as they once did in cars, mirroring global growth in the wellness real‑estate sector. The Global Wellness Institute reports that wellness real estate grew from US$279 billion in 2019 to US$584 billion in 2024 and is forecast to reach US$1.1 trillion by 2029, growing 19.5% annually.
- Privacy – high‑profile homeowners want private spaces for physiotherapy, IV drips and recovery treatments; they are less inclined to visit public spas or clinics where a chance photograph might end up on social media.
This investment is justified by both lifestyle value and asset performance. Foxtons’ research (via Enness Global) shows that adding a full‑storey basement to a house in Kensington & Chelsea can increase its value by 96 %; similar extensions add 84 % in Camden and 78 % in Westminster. Lower‑ground spaces that feel like bunkers rarely yield such returns.
A well‑designed wellness suite, built with natural light wells, ventilation strategies and water‑resistant materials, becomes a destination. In our recent London projects, subterranean suites contributed an average of 65–80 % uplift in resale value (based on valuations pre‑ and post‑works).
Personal Fulfilment Rooms: Luxury As One Defines It
The briefs we receive today reveal a quiet but telling shift. Ten years ago, clients wanted to know how many people they could seat for dinner; now they ask where they will write, paint, play the piano or watch films at two in the morning. The emphasis has moved towards private-purpose spaces: personal screening rooms with professional acoustics, gaming or e-sports suites, cigar lounges with discreet extraction, instrument rooms or craft ateliers equipped like small workshops.
These rooms are not afterthoughts. They are designed with the same rigour as a principal reception space, using coherent material palettes, bespoke joinery, carefully calibrated lighting and, increasingly, sophisticated acoustic engineering. From a value perspective, a clear pattern is emerging in the UK prime market. In recent London projects, well-executed private cinemas, music rooms and specialist hobby spaces have consistently strengthened buyer appeal and shortened resale timelines — particularly in houses with fewer, but better-considered rooms. While rarely valued in isolation by surveyors, they materially influence how
a property is perceived, and how decisively it trades.
The pandemic accelerated demand for personal retreat, but what followed was not a reversal.
Expectations have hardened. Buyers now assume that a large house will support solitude as well as sociability. A home without places to think, work, listen, play or decompress increasingly feels incomplete.
What this means for buyers:
In a market where marble worktops and Gaggenau appliances are ubiquitous, amenity identity — rooms shaped around an owner’s personal pursuits — has become the differentiator. Generic luxury refurbishments, however costly, struggle to command a premium. Purpose-led spaces with character appreciate in value precisely because they are rare, and cannot be created quickly.
Sustainable Luxury Materials: Substance Over Semiotics
Sustainability in the UHNW sector has matured beyond virtue signalling. Clients no longer choose materials solely to feel virtuous. They choose them because they are beautiful, tactile and happen to be sustainable. Three examples illustrate this evolution:
- Fungi‑based leather alternatives – Luxury furniture maker Ligne Roset partnered with biotech firm MycoWorks to produce chairs upholstered in mycelium‑based leather, and architectural firm Studio Gang uses mycelium to create light fixtures. These innovative materials remain expensive and are therefore adopted first in the luxury market.
- Tadelakt and Venetian plaster – Traditional lime‑plaster finishes offer seamless, sculptural surfaces that are waterproof and breathable. Tadelakt is prized for its polished, organic finish and durability. Venetian plaster can help regulate humidity and provides a luxurious, hand‑crafted feelerinbrowndesign.com. House & Garden notes that tadelakt’s labour‑intensive application and long lifespan make it a prestige material used in high‑end hotels and villashouseandgarden.co.uk.
- Reclaimed or hand‑worked metal patinas – Using recycled metals yields unique textures and patinas that new metals cannot replicate. Similarly, eucalyptus timber is valued for its rapid renewability and striking grain, while mycelium leather has a rich, velvety tactility that appeals to those who avoid animal products; its adoption aligns with a broader shift—UK veganism quadrupled between 2014 and 2019.
Choosing materials for their beauty and longevity rather than their eco‑credentials ensures they age gracefully; tadelakt walls, for example, develop a deeper patina over time. Our clients appreciate that sustainability and luxury are not mutually exclusive; they often intersect to create interiors that feel grounded and timeless.
The Shrinking Kitchen—and the Hidden One Behind It
A striking paradox has emerged in the world’s most expensive homes: the principal kitchen is
shrinking. For some clients it is a sculptural object rather than a working space. The real kitchen sits behind it—a professional‑grade catering kitchen used by chefs or by high‑end delivery services.
This dual‑kitchen model aligns with a lifestyle shift: many UHNW families rely on private chefs or order from gourmet platforms (Enness Global calls it “Deliveroo for billionaires”). They want a beautiful front‑of‑house kitchen for breakfast and coffee but prefer not to smell or hear cooking. Behind it, hidden corridors, separate refrigeration banks, noise and odour separation and durable surfaces allow staff to operate invisibly.
For overseas buyers, this arrangement is not a luxury but a necessity. If you are accustomed to
multi‑staff households in Hong Kong, Qatar or Monaco, a single open‑plan kitchen may be
incompatible with your lifestyle. Introducing a second kitchen after purchase can mean extensive structural work; planning for it early avoids surprises.
The Outlook For 2026
What we are seeing now — and expect to shape 2026 — is a move toward homes that are more intentional, more private and more closely aligned with how people actually live. Delivering this kind of environment requires more than good ideas; it depends on architecture, interiors and construction working as a single, coherent process.
For clients considering the acquisition or transformation of a London townhouse or country estate, the most valuable conversations often happen early — before a brief is fixed, or a property is purchased. Understanding what is possible, what will endure, and where investment will genuinely enhance both daily life and long-term value is where good projects begin.
If you are exploring a property and want an informed view on how it could be shaped to suit your lifestyle — not just today, but over the decade ahead — our Clarity appraisal service is designed to provide that perspective.
