CAD Maps
for Architects .
Professional Ordnance Survey plans delivered as editable DWG & DXF files - built from live OS MasterMap Topography and OS NGD data. Ordered online, delivered in minutes, ready to drop into your drawing set.
Built for the way architects actually draw.
Not a raster screenshot. Not a flattened PDF. Every output is a properly-structured CAD file that respects how you work - layered, scaled, and georeferenced.
Editable CAD layers
Buildings, roads, kerbs, rail, water, boundaries - each on a named layer, correctly typed, ready to trace.
Precise scales & extents
Pick anything from 1:200 block plans to 1:2500 location plans. Define extent by radius, address, or drawn boundary.
DWG + DXF delivery
Delivered in R2018 DWG plus DXF for legacy compatibility, ready for architectural and planning workflows.
Georeferenced to BNG
Every drawing lands in the British National Grid (OSGB36 / EPSG:27700) so it stacks with survey data perfectly.
Red-line title plans
Add HM Land Registry title polygons as a locked boundary layer for planning submissions.
Delivered in ~90 seconds
Online ordering tool. Area selected → map generated → download link in your inbox. No tickets, no waiting.
Six layers.
One coherent plan.
Each CAD map ships as a structured stack. Turn layers on and off, freeze what you don't need, or pull a single feature class into your template. Nothing is baked in.
| LAYER | FEATURE CLASS | COLOR |
|---|---|---|
| L-ANNO-DIMS | Dimensions | BYLAYER · 7 |
| L-SITE-BNDRY | Boundary polygon | RED · 1 |
| L-ADDR-PTS | NGD address points | YELLOW · 2 |
| L-ROAD-CRLN | NGD transport | GREY · 9 |
| L-BLDG-FOOT | MasterMap buildings | CYAN · 4 |
| L-TERR-CNTR | Terrain contours | GREEN · 3 |
What architects actually do with them.
Planning applications
Location plans at 1:1250, block plans at 1:500, and red-line title boundaries - everything a local authority will accept, first time.
- →1:1250 location plans
- →1:500 block plans
- →Red-line title overlay
- →North arrow & scale bar
Feasibility & massing
Drop accurate site context under your 3D massing. Setback lines, party walls and neighbouring footprints correct to the metre.
- →Neighbouring footprints
- →Site envelopes & setbacks
- →Right-to-light studies
- →Clean import to Revit/Rhino
Site analysis
OS Terrain contours, vegetation, watercourses and road hierarchies - context layers for early-stage design review.
- →Contours at 1m / 5m
- →Vegetation & water
- →Road classification
- →Access & hierarchy
