53 Mount Ephraim Lane

Streatham, London, Greater London

Independent reading

A radically modernised 3,897 sq ft detached London house with a 5.5-metre kitchen, cinema, climbing wall, 750-bottle cellar and private one-third-acre garden beside Tooting Common.

53 Mount Ephraim Lane clears the Pavello benchmark through unusually ambitious architecture and interiors, a genuinely private detached setting and a complete city-lifestyle programme. The £1,026/sq ft headline uses the 3,897 sq ft figure independently aligned between the live instruction and the May 2026 exact-address EPC record. A legacy property portal retains 456 sq m / about 4,908 sq ft, which would imply about £815/sq ft; that older boundary is not interchangeable with the current signed-market and energy figure until a RICS component schedule separates the basement, garage mezzanine and garden room.

Identity confidence99%

53 Mount Ephraim Lane, Streatham, London
The live Savills instruction, current Rightmove and OnTheMarket distribution align on a detached freehold house in Mount Ephraim Lane, SW16 1JE at a £4m guide with six bedrooms, five bathrooms, four receptions and 3,897 sq ft. The exact-address May 2026 EPC-derived record identifies 53 Mount Ephraim Lane as detached, 362 sq m / 3,897 sq ft, EPC C77 and Council Tax F; the HM Land Registry-derived postcode table records the same address as detached/freehold with its £1.328m August 2015 transfer; and the official Lambeth parking order independently names the boundary at Nos. 51 and 53. The marketed facts, exact area, energy, tax band, detached form, postcode and transaction history produce a decisive exact-property match even though the official title and UPRN remain buyer-side.

  1. Savills currently offers the property at a £4m guide as a detached freehold house with six bedrooms, five bathrooms, four receptions, 3,897 sq ft and approximately one-third of an acre.
  2. The kitchen has a 5.5-metre ceiling, bespoke cabinetry, Gaggenau appliances, black limestone and direct garden access; the principal reception connects to a fitted library.
  3. The lower-ground lifestyle level contains a 6.5-metre climbing wall, cinema with a 10-foot screen and 5.1 sound, and a temperature-controlled cellar for about 750 bottles.
  4. The gated gardens include an outdoor kitchen, irrigation, petanque court, table-tennis area, fruit trees, a 200-year-old oak and a garden office with kitchenette and WC.
  5. Underfloor heating, air-conditioned bedrooms, oak parquet, Crittall-style doors, garage mezzanine, CCTV and entry-phone systems support an outstandingly modernised specification.
  6. The exact-address May 2026 record independently attributes 362 sq m / 3,897 sq ft, EPC C77, Council Tax F and a three-band improvement from the 2015 F34 certificate.

Investigate next

  1. Obtain the official title register and plan, UPRN and measured one-third-acre extent, confirming the detached plot, boundaries, access, parking, garden structures, covenants, services, drainage and every tree or conservation obligation.
  2. Retrieve the complete planning and Building Control archive for 17/03148/FUL, 18/01010/VOC and every linked condition discharge, basement-impact assessment, construction-method statement, window, outbuilding and tree consent, then join each approval to completion evidence.
  3. Commission a signed RICS component measurement reconciling the current 362 sq m / 3,897 sq ft instruction and EPC with the legacy 456 sq m / about 4,908 sq ft property record, separating habitable accommodation, basement, garage mezzanine and garden room.
  4. Obtain three years of energy, water, air-conditioning, security, irrigation and garden records; commission specialist basement-waterproofing, structure, roof, solid-wall, glazing, M&E, drainage, tree, subsidence, noise and property-level environmental reviews.
