Luxury Flooring for London Homes: Stone, Marble and Hardwood

Flooring is one of the most consequential decisions in any luxury renovation. It is the surface that every visitor walks on, the one that gets photographed in every estate agent shot, and the one that is most visible over the decades of the building's life. It also happens to be the decision that is most often rushed — left until late in the design process, treated as a finishing touch rather than an architectural element.

In a well-specified London renovation, the flooring is designed from the beginning. It determines junction details, room heights, heating system choices, and the overall material language of the interior. This guide covers the main options and what you need to know about specifying each.

Natural stone

Natural stone — marble, limestone, travertine, granite, slate, and others — is the default choice for prime London properties at the highest specification. Its appeal is not merely aesthetic: properly maintained stone flooring can outlast the building itself, and it improves with age in a way that no manufactured product can replicate.

Marble

Marble is the most prestigious and the most demanding of the natural stones. At ASAAN, our marble specification and restoration work is one of the services we are most frequently commissioned for, and the range of what can be achieved is significant.

Key decisions when specifying marble:

Grade and source. Marble is quarried in thousands of varieties worldwide. Carrara, Calacatta, Statuario, Nero Marquina, Emperador — the distinctions in veining, background colour, and character matter enormously. Within any named marble variety, individual slabs vary significantly. For a prominent application — a hall floor, a feature bathroom — it is worth book-matching slabs from the same block, which requires visiting the yard or working with a supplier who will do so on your behalf.

Finish. Polished marble is the traditional choice and gives the highest reflectivity. Honed gives a matte, more contemporary look and is more forgiving of scratching. Brushed and tumbled finishes create an aged appearance appropriate for period interiors. Each finish has different maintenance implications: polished marble shows water marks and scratching more readily, but is also the easiest to restore to a like-new condition.

Thickness and format. Standard tiles are 10–12mm. Slab formats (for minimal jointing) start at 20mm and are significantly heavier. The floor structure needs to be able to carry the load, which in older London buildings requires a structural assessment before committing to a large-format stone installation.

Heating. Marble is compatible with underfloor heating but has specific installation requirements — slower warm-up schedules, appropriate movement joints — that a specialist installer needs to account for. Getting this wrong causes cracking.

Limestone and travertine

Limestone is more porous than marble and softer, which means it is more susceptible to staining and surface wear in high-traffic areas, but also warmer underfoot and easier to source in consistent large quantities. Travertine — a form of limestone — is distinguished by its characteristic voids, which can be left open (unfilled) for a rustic look or filled for a smooth contemporary surface.

Both are excellent choices for large-format floor applications, particularly in more informal or warm-toned interiors where marble's luxury associations are too formal.

Maintenance and restoration

Natural stone floors require sealing on installation and periodic resealing over their life. Polished marble can be re-polished if it becomes scratched or dull — this is a specialist process using diamond pads and restoration compounds, and when done properly returns the stone to its original condition. See our marble restoration guide for more detail on the maintenance requirements.

Solid hardwood

Solid hardwood flooring — boards milled from a single piece of timber — is the premium choice for reception rooms, bedrooms, and studies in London townhouses and apartments. It offers the warmth, acoustic properties, and patina that no engineered alternative matches, and in well-maintained older properties, the original solid timber floors are often among the most valuable features of the building.

Species. The choice of timber species determines colour, hardness, grain character, and cost. European oak is the standard for high-specification London interiors — stable, durable, widely available, and versatile in terms of finish. Other choices include American walnut (darker, more figured, premium cost), ash (paler, contemporary), and wide-plank reclaimed timbers for period interiors.

Width and length. Wider boards look more expensive and more bespoke but require a more stable subfloor and a longer acclimatisation period. The conventional rule is that a board should not be wider than five times its thickness, but in practice solid boards above 120mm are uncommon; engineered hardwood is usually the correct choice for very wide-plank applications.

Grade. Hardwood grades describe the character of the wood: rustic grades have more knots, colour variation, and character marks; prime/select grades are cleaner and more uniform. The correct choice depends on the aesthetic — a rustic grade in a Georgian drawing room can look wrong; a select grade in a relaxed country-house-style interior can look clinical.

Finish. Oil finishes penetrate the wood and preserve its natural feel; they need periodic re-oiling but are easy to spot-repair. Lacquer finishes are more protective but create a plastic-like surface and require full floor refinishing when they fail. Hardwax oil is a hybrid that has become the standard choice for high-specification London work — more durable than pure oil, more natural-feeling than lacquer.

Engineered hardwood

Engineered hardwood has a real hardwood wear layer — typically 4–6mm of solid hardwood — bonded to a stable plywood substrate. It offers the appearance and most of the quality of solid hardwood, with greater dimensional stability (it moves less with temperature and humidity changes) and compatibility with underfloor heating.

For wide-plank formats (above 150mm), engineered hardwood is generally the better choice than solid. It is also the correct choice where the floor is being laid over a screed with underfloor heating.

The quality range is large. The cheapest engineered hardwood has a 2mm wear layer that cannot be sanded and refinished. The best has a 6mm wear layer and is indistinguishable from solid in appearance and performance.

Herringbone and parquet

Herringbone and parquet patterns — whether in solid or engineered hardwood — are a defining feature of high-specification London interiors. They are more time-consuming to lay, require more material (accounting for cuts), and demand precise subfloor preparation, but the result is categorically different from straight-laid boards.

The border detail — whether the herringbone is contained within a plain border of the same or contrasting timber — is worth considering carefully. It adds visual formality and is always worth doing in a reception room of sufficient quality.

Specification decisions that matter

Subfloor preparation is the most important determinant of floor quality and longevity. An uneven, damp, or structurally compromised subfloor will cause movement, creaking, and joint failure in any floor laid on top of it. It is not a place to economise.

Junctions and thresholds — where flooring transitions between rooms, between materials, or at door openings — are a detail that distinguishes a well-designed installation from an improvised one. These should be designed, not resolved on site at the last minute.

Acoustic performance is relevant in any multi-storey property, and in apartments and managed buildings is often subject to building management requirements. The floor build-up (subfloor, acoustic mat, adhesive or clip system, finish) needs to achieve the specified impact and airborne sound reduction. Getting this wrong can mean failing the building management sign-off and having to lift the floor.
