Local drone surveys in Theydon Bois, planned around the site and the airspace.
Theydon Bois has kept its shape in a way few Central line villages have: a very large green, a lime-lined main road, Epping Forest on three sides and a strong local preference for keeping it that way. That changes what we get asked to do here. There is less roof-only work and more whole-plot survey — levels and falls across long gardens and paddocks, extents for Green Belt planning applications, canopy cover measured against a proposed extension, and drainage runs on properties sitting on London clay that slopes towards the Forest. It is also about five miles by road from our base at North Weald, which means a Theydon job can usually be scoped, flown and off site inside a morning.
The buildings and sites we survey in Theydon Bois
Theydon Bois is low-density and mostly detached. Victorian and Edwardian houses sit around the green and along Coppice Row, with substantial interwar detached homes on Piercing Hill, Theydon Park Road and Loughton Lane, and post-war infill on generous plots. Plain and interlocking clay tile is common, slate on the older stock, and a great many roofs have been altered by loft conversions, rear extensions and later dormers — which is exactly where the junctions fail. Beyond the built-up edge the parish is Green Belt: paddocks, stabling, the golf course and the Forest boundary, so plots are often irregular and worth measuring properly before any application.

Drone surveys in Theydon Bois — frequently asked questions
Why would I need a topographic survey in Theydon Bois?
Because plots here are large, irregular and rarely flat. If you are extending, building a garden room, resiting a stable block or dealing with water collecting at the bottom of the garden, your architect or engineer needs contours, levels and spot heights rather than a photograph. We capture the whole surface from the air and deliver a scaled drawing your design team can work from, with the accuracy achievable agreed at the briefing stage.
How close are you to Theydon Bois?
About five miles by road. We are based at North Weald near Epping, straight up the B172 and B1393, so Theydon is one of the quickest sites we attend. That usually means more flexibility on dates and a shorter time on site, and it means we already know the local airspace picture — the Stansted TMZ overhead and North Weald's circuit traffic — rather than researching it from scratch.
Can you fly over the village green or the Forest?
The green and the surrounding Epping Forest are managed land, and take-off and landing there need the landowner's permission, which we do not assume we have. For a private survey we launch and recover from your own garden, driveway or paddock. That keeps the aircraft close to the subject, keeps walkers and riders well clear, and avoids relying on a permission that has not been granted.
Does the Stansted airspace stop you flying in Theydon?
No, but it shapes the plan. Theydon sits under Stansted's transponder mandatory zone airspace — we confirm its exact boundaries on the current NATS map — and North Weald's traffic operates a few miles north. The Open category height limit of 120 metres (400ft) applies anyway, well below that. We check the NATS UAS restriction map and current NOTAMs before every flight and brief you on anything that affects timing.
