What Mason Navarro Pledge does

Mason Navarro Pledge (MNP) is a UK-based consulting civil and structural engineering firm with offices in London (Clerkenwell Green, headquarters), Hitchin (Hertfordshire), and Manchester. The firm delivers structural and civil engineering services — including new-build design, refurbishment, vertical extensions, basement construction, drainage strategies, sustainable drainage systems (SuDS), and flood risk assessment — to UK real estate developers, heritage property owners, local authorities, and educational institutions. Its specialism in heritage and conservation engineering, anchored by former Historic England engineering lead Stuart Ellis, addresses listed-building structural appraisals, sensitive refurbishment, and minimum-intervention approaches for Grade I, Grade II, and scheduled monument assets.

The firm's technology stack revolves around BIM and 3D modelling using Tekla Structural Designer and Revit, complemented by drone-based photogrammetry for surveying and monitoring derelict or at-risk structures. Supporting services include temporary works design and on-site construction-phase support. MNP delivers project-based engineering consultancy fees (professional services model) on an assignment-by-assignment basis, with no standard price list; projects range from small heritage works to multi-hundred-unit residential developments and have historically spanned in excess of £1.4 billion in construction cost. The firm is privately held, with no external investors or funding rounds disclosed, and operates from three UK offices serving projects across England including London, Manchester, Liverpool, the Home Counties, and the South East.
