Our Approach

An ethical approach to every undertaking

Surveyor on site representing professional ethics and standards.
01

Ethics

We are regulated by the Royal Institution of Chartered Surveyors and professional ethics are central to our ethos.

Surveying and inspection work that reflects efficient professional practice.
02

Efficiency

As an RICS Tech Partner we build surveying software, including in-house tools that shorten the gap between site inspection and issued report.

Detailed building inspection image representing transparency and integrity.
03

Integrity

Advice is given against the lease and the evidence on site, not against the outcome a client prefers. Where a defect is overstated or outside tenant liability, we say so in writing.

04

Sustainability

Inspection routes are planned to limit site visits. Reports are delivered digitally and reuse photographs and CAD data already gathered for the survey.

Where Roof Design Meets Condensation Risk

Two timber-framed roof lanterns formed part of a recent external inspection we undertook on a mansard roof in West London. Both featured single glazed elements, limited overhangs, and decorative paint finishes in poor condition.

The presence of condensation to internal glazing, along with signs of historical repair and timber exposure, highlights a common set of issues—particularly in traditional or poorly detailed roof structures.

Where single glazed rooflights are retained in occupied spaces, internal dampness is frequently the result of thermal bridging or trapped moisture, rather than rainwater penetration alone.

In such cases, replacement offers the opportunity to introduce modern, thermally efficient materials and more robust junction detailing—reducing risk and improving long-term performance.

About Marylebone

Marylebone

Marylebone sits in the City of Westminster in central London, between Regent's Park and Oxford Street, an affluent residential, professional, and retail area defined by exceptional Georgian and early-Victorian stucco-fronted terraces and townhouses across the streets of the Howard de Walden and Portman estates, substantial Victorian and Edwardian mansion blocks, listed institutional buildings around Harley Street and the medical quarter, the retail frontage of Marylebone High Street and Oxford Street, and selective recent high-specification residential and mixed-use development. Typical building types include listed Georgian and early-Victorian townhouses, Victorian and Edwardian mansion blocks, period commercial and consulting-room premises, and recent high-value apartment developments. Surveying instructions in Marylebone commonly include pre-purchase surveys on listed and period stock, technical due diligence on investment transactions, schedule-of-condition and dilapidations work on office, consulting-room, and retail leases, and party wall and basement advice.

Listed and Estate-Managed Stock

Marylebone's residential streets sit within extensive conservation-area designations, with substantial listed-building coverage and estate-management controls from the Howard de Walden and Portman estates. Pre-purchase and pre-lease assessments require detailed attention to stucco render and brick condition, parapet and valley gutter performance, timber sash window and cornice joinery, slate mansard roofs, and the cumulative impact of successive conversions. Estate consent requirements add a further layer of control beyond local authority conservation-area and listed-building obligations.

Harley Street and Professional Leases

The Harley Street medical quarter generates distinctive commercial lease work — schedules of condition at lease commencement, licences to alter for consulting-room and clinic fit-outs, reinstatement costings, and dilapidations claims at lease expiry. Clinical ventilation, acoustic separation, and fire safety are common licence-to-alter themes. Office and retail stock along Marylebone High Street, Wigmore Street, and the surrounding streets supports further schedule-of-condition, dilapidations, and CAT A and CAT B work.

Basements, Party Walls, and Mansion Blocks

High property values have generated an active basement excavation market. Party wall work under the Party Wall etc. Act 1996 is extensive, with detailed schedules of condition on adjoining owners essential. Victorian and Edwardian mansion-block stock presents communal-element and leasehold considerations central to purchaser advice, including service-charge adequacy, sinking-fund provision, and Building Safety Act compliance.
