Installing a lift in a London townhouse or mews property is increasingly common at the top of the market. Here is what the process involves from structural design to final commissioning.
Residential lifts were once a feature of only the largest and most formally arranged London properties. Increasingly, they are specified in four- and five-storey townhouses, mews properties, and apartment buildings where multiple floors and ageing-in-place are both relevant considerations.
This is what a residential lift installation actually involves — not a salesperson's overview, but a construction perspective.
The case for a residential lift
In a multi-storey London townhouse, a lift serves several purposes:
Practicality: Carrying heavy items, luggage, and groceries between floors is a genuine quality-of-life issue in a four-storey house. A lift makes the upper floors more accessible and usable for daily life.
Future-proofing: A client who installs a lift at 40 does not need it yet. At 75, they will. Installing it as part of a major renovation costs a fraction of what a retrofit would cost once the house is finished and occupied.
Value: At the top of the London residential market, a well-installed lift is increasingly an expected feature rather than a luxury. Properties without one are sometimes perceived as incomplete at the highest price points in Mayfair, Belgravia, and Kensington.
Lift types: the main options
Hydraulic lifts use a hydraulic ram to raise and lower the car. They are smooth and quiet, require a machine room (hydraulic unit), and have a limited travel height — typically suitable for up to five floors. The hydraulic fluid poses an environmental risk in the event of a leak; modern systems use biodegradable fluids.
Traction lifts (electric) use electric motors with counterweights and cables. They can travel higher, stop more precisely, and are more energy-efficient than hydraulic lifts. The machine room can be located at the top or incorporated within the shaft on modern designs (machine-room-less, MRL traction). MRL traction lifts are the most commonly specified in new London residential installations.
Pneumatic (vacuum) lifts use air pressure to raise and lower the car. No shaft required — the cylindrical unit is freestanding. Very compact and architecturally striking. Limited capacity (typically one or two passengers) and a sound quality different from conventional lifts. Suitable for properties where shaft construction is not possible and the load requirement is low.
Platform lifts are not lifts in the conventional sense — they are open-sided or semi-enclosed lifting platforms suitable for accessibility applications and low-traffic inter-floor movement. Not appropriate as a primary residential lift but useful as an alternative where shaft space is too limited for a conventional installation.
Structural requirements
A residential lift requires a structural shaft. In a new-build or whole-house renovation, this can be designed in from the start. In a retrofit, it requires careful structural design — the shaft must have load-bearing walls or a steel frame, and it must penetrate floor slabs at every level.
Pit: Most conventional lifts require a pit below the lowest stop — typically 150–400mm deep. This affects ground floor slab design. In a basement renovation, the pit must be waterproofed and designed into the basement slab from the outset.
Headroom: The top of the shaft must have adequate clearance above the highest stop — typically 2.4–3.6m depending on the lift type and speed. In a period property with a limited loft space, this can be a constraint.
Machine room (where required): Hydraulic lifts require a machine room adjacent to the lowest level (for hydraulic units). MRL traction lifts incorporate the machinery within the shaft, eliminating this requirement.
Structural loads: The lift car, machinery, and counterweight impose concentrated loads on the shaft structure. These must be calculated by a structural engineer and the shaft designed accordingly.
Shaft construction
In a period London townhouse, the lift shaft is typically constructed within the building — either carved from existing space or added as part of a rear extension. Options:
- —Steel-framed glass shaft: The contemporary preference at the luxury end. Fully glazed on at least one or two sides, with a structural steel frame. Visible from the adjacent circulation space; can be a design statement.
- —Masonry or blockwork shaft: Traditional enclosed shaft, plastered and finished to match the surrounding space. The lift car interior is visible; the shaft is not.
- —Purpose-built structural shaft within a new extension: The cleanest structural solution, where the lift shaft is the structural spine of an added extension.
Planning and Building Regulations
Planning permission: Installing a lift internally within an existing dwelling does not typically require planning permission. If the lift shaft requires an extension to the building envelope, planning permission is required. In a conservation area, any extension requires permission and careful design.
Building Regulations: All lift installations must comply with Building Regulations Part M (accessibility) and be certified to the appropriate British/European standard (BS EN 81-40 for stairlifts and inclined lifts; BS EN 81-41 for vertical platform lifts; EN 81-1/2 for conventional passenger lifts). The lift supplier will typically manage the inspection and certification process; the builder is responsible for the shaft construction compliance.
Party wall: If the shaft abuts or is close to a party wall, party wall notices may be required. The structural design of the shaft must not impose loads on the party wall.
Lift car specification
The lift car interior is a joinery project as much as a mechanical installation. Options range from a plain painted interior to fully bespoke panelling in leather, timber, stone, or metal. At the luxury end, the lift interior should be specified alongside the rest of the house interior — materials should be consistent with the primary circulation spaces.
Key elements to specify: car size (standard residential cars are 800–1200mm wide, 1000–1400mm deep), door type and finish (typically brushed stainless steel or painted metal), floor finish (stone, timber, or carpet), ceiling lighting, and control panel design.
Cost benchmarks
Residential lift costs in London:
| Specification | Total installed cost |
|---|---|
| Basic MRL traction lift, standard car, minimal shaft | £45,000–70,000 |
| Mid-specification glass shaft, custom car interior | £80,000–130,000 |
| High-specification bespoke installation, luxury car finish | £130,000–250,000 |
These figures include shaft construction, lift supply and installation, Building Regulations compliance, and finishing. They exclude structural design fees (typically £3,000–8,000 additional).
ASAAN's approach
ASAAN has installed residential lifts as part of complete townhouse and mews renovations across prime London. We manage the structural shaft as part of the construction contract and coordinate with specialist lift suppliers for the mechanical installation.
