Pre-Development Insight, Delivered Through Practice and Tools
SPΔD3 (Spatial Planning Δ Design & 3D)provides free pre-development support across planning, flood risk, drainage and spatial analysis.
We help clients reduce uncertainty early, strengthen technical confidence, and produce clear, defensible outputs that stand up in professional review and decision-making. In parallel, SPΔD3 builds and maintains a suite of digital applications—published through Dock-Base, our delivery platform for tools.
This includes tools such as EFRA and Utility3D, alongside calculation, review and visualisation utilities used across feasibility, option appraisal and early-stage infrastructure planning. Whether you engage SPΔD3 through consultancy or through Dock-Base tools, the objective is the same: higher-quality early decisions, improved coordination, and fewer avoidable risks downstream.
Services and Platforms
SPΔD3 operates as both a specialist technical practice and a product studio. We deliver professional pre-development advisory work, and we also publish practical tools via Dock-Base to support repeatable tasks, consistent quality, and faster early-stage assessment.
Flood Risk & Drainage Feasibility
Used by developers and planners to test feasibility, challenge assumptions, and prepare evidence early.
Spatial Due Diligence and Constraint Mapping
Delivered through Decision-Grade GIS analysis, 3D terrain models, and Dock-Base Site Intelligence tools that make complex data usable.
Digital Tools & Utilities
Dock-Base, Site Tools and 3D Utilities Tools
Calculators, checkers, and visual tools developed through SPΔD3 and published via our platform Dock-Base for wider use. EFRA, Utility3D and Supporting Apps
From Tools to Strategy
Many conversations with us begin through Dock-Base. People use an platform to test an idea, sense-check a site, or understand a constraint ; then make contact when they need context, judgement, or planning-ready outputs.
This link between hands-on tools and professional insight allows SPAD3 to stay grounded in real-world problems while scaling access to expertise.
