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 Stockley Park

Stockley Park Office Buildings

Stockley Park is a 150-acre business park in the London Borough of Hillingdon, between Hayes and West Drayton and immediately north of Heathrow Airport, developed from the mid-1980s on reclaimed landfill land around a series of lakes and an 18-hole golf course. The park accommodates a substantial stock of HQ-grade and multi-let office buildings, with tenants drawn from technology, pharmaceuticals, financial services, and logistics-related corporate functions, alongside ancillary amenity and conference facilities. Typical building types include late 1980s and 1990s steel and concrete-framed office buildings of three to six storeys, with curtain-wall and rain-screen cladding, central or end-bay atria, raised access floors, four-pipe fan-coil mechanical ventilation, suspended ceilings, and surface or undercroft car parking. Surveying instructions at Stockley Park commonly include dilapidations and schedules of condition on office leases, category-A and category-B fit-out advice, reinstatement cost assessments, Minimum Energy Efficiency Standards strategy, and condition appraisals on curtain wall, rooflights, and rooftop plant.

Office Building Stock and Common Defects

The office buildings at Stockley Park are predominantly late 1980s and 1990s steel-framed structures with curtain-wall and rain-screen cladding, central or end-bay atria, raised access floors of 150 mm to 300 mm void depth, four-pipe fan-coil mechanical ventilation, perimeter heating, suspended mineral-tile ceilings, and three to six-storey podium and core arrangements. Roof coverings are typically single-ply or built-up bituminous membrane on flat or shallow-pitched warm roofs, with extensive rooftop plant compounds for cooling, ventilation, and emergency power. Common defects include sealant failure and gasket degradation at curtain-wall joints, water ingress at atrium glazing and rooflight perimeters, end-of-life chiller and boiler installations, raised access floor damage and inadequate void coordination after multiple fit-outs, suspended ceiling tile degradation, dated category-A finishes that fall short of current Grade A specification expectations, and flat-roof membrane ageing at upstands and outlets.

Office Dilapidations, Category-A and Category-B Fit-Out, and MEES

Tenants and landlords at Stockley Park face material dilapidations exposure on office leases, driven by the age of the building services, the cumulative impact of successive fit-outs, and the cost of returning premises to a defined category-A specification. A schedule of condition recorded at lease commencement is intended to limit terminal dilapidations liability and is routinely instructed for all new leases at the park. Terminal schedules require assessment of category-A reinstatement (raised floors, ceilings, mechanical and electrical services, perimeter finishes), removal of category-B fit-out (partitioning, joinery, IT cabling, kitchenettes), and statutory obligations including asbestos in the older buildings and Minimum Energy Efficiency Standards. MEES strategy is increasingly central to dilapidations and asset management because letting and continued occupation under the EPC regime require careful planning around plant upgrade, lighting, and fabric improvements.

Reinstatement Cost Assessment and Continuing Investment

Reinstatement cost assessments at Stockley Park need to reflect the replacement cost of large-floorplate steel-framed office buildings with curtain-wall envelopes, raised access floors, four-pipe fan-coil services, atria, and rooftop plant, together with professional fees, demolition and debris removal, and any reinstatement of landscaped surroundings. Continuing investment in the park, including refurbishment of mid-1990s buildings to current Grade A office specification and the addition of new amenity and life-sciences floorspace, generates schedule of condition work for adjoining occupiers, party wall awards, and pre-construction condition records on neighbouring buildings. Owners considering capital expenditure on refurbishment or repositioning need early advice on existing-building condition, MEES compliance pathways, and the costs and risks of retained versus replaced building services.
