Paddington dig stock mixes canal-edge apartments, period terraces and mansion blocks. Freehold control of subsoil is proven before any temporary-works conversation; multi-lease W2 conversions usually redirect to Licence to Alter rather than excavation.
Westminster basement Article 4 applies; Paddington Green and boundary CA contexts are fixed per pin. Lightwells need full householder evidence — not a PD shortcut and not a Bayswater terrace package reused without map checks.
Title is the first Paddington sheet. Lessees who do not control the ground are stopped before boreholes. Freehold single-family pins proceed to investigation only after garden rights are clear.
Under a Paddington house, ground conditions are established by trial pits and boreholes on this plot — not by a finished basement two streets away — because made ground, groundwater and foundation depths drive retaining design, waterproofing grade and neighbour movement predictions here.
Spoil near arterial roads and station approaches is a feasibility gate. Awards, monitoring and loading bays are programmed with access surveys, not left as tender footnotes.
Below the existing drainage invert of a Paddington house, waterproofing is designed to BS 8102 with dual protection and pumped discharge; pumps need power, backup and lifelong servicing so rooms stay usable rather than merely dry.
Tight urban courts and canal-edge outlook set lightwell size before habitable room counts. Guarding and daylight are designed for the real court, not a catalogue under-garden cinema.
Where ownership splits or access kill digs, we price rear or loft alternatives early so excavation is a choice, not a default W2 brief.
Paddington Green archaeological-priority and ancient-village context can force early ground, drainage and basement assumptions that pure Bayswater stucco-pair digs never open with.
Canal-edge and station-edge access for spoil near arterial W2 routes is a Paddington feasibility gate — mixer and skip routing is surveyed before BIA fees, not after awards.
Mixed terrace, mansion-block and canal-side stock means many ‘Paddington basement’ enquiries are really freeholder flat problems; we stop dig briefs at title when subsoil is not controlled.
Compared with Lancaster Gate park-front formality, Paddington more often turns on Westbourne/Bayswater boundary CA checks and tight urban courts without a formal garden square.
Paddington programmes: freehold subsoil → archaeological/ground notes if on priority area → arterial access → lightwell courts → Westminster basement evidence. We refuse to paste a Pimlico Cubitt-terrace dig narrative onto canal-edge stock.
Little Venice and Edgware Road edges produce different construction-hour and loading constraints from Hyde Park terrace fronts — written per pin, not as one W2 template.
A Paddington client pack that unlocks design is freehold proof, pin map for archaeological priority if relevant, photos of the court and a realistic arterial spoil route — not a Bayswater Queensway mansion-block checklist alone.
Canal-edge and station-edge pins more often fail on loading bays and skip routing than on formal garden-square lightwell formality that dominates Lancaster Gate.
We redirect multi-lease canal-side conversions to Licence to Alter early when subsoil is not controlled, rather than selling a dig brief the freeholder will refuse.
A Paddington basement package is sequenced as survey, investigation, structure, Westminster drawings, party wall mapping and building regulations — approval is never promised; the goal is to remove avoidable refusal and neighbour deadlock. Clients should expect a longer pre-construction period than for a simple rear extension, and most digs are easier with the house empty for part of the works.
