Structural Drawings in Greenwich SE10
Fixed-fee, MCIAT-chartered structural drawings for Greenwich (SE10) homeowners — Royal Borough of Greenwich validation and local constraints handled from the start.
Greenwich (SE10) is among the most heritage-sensitive places to build in London: most of its period housing sits within one of the Royal Borough's conservation areas — West Greenwich, Greenwich Park, East Greenwich or the Ashburnham Triangle — and three of those carry Article 4 directions that pull nearly all external work into the planning system. Side-return and rear extensions on the Victorian and Georgian terraces are the staple, but they are judged carefully on materials, proportion and detail.
SE10 also sits within, or beside, the Maritime Greenwich World Heritage Site: the inscribed core is the Old Royal Naval College, Queen's House, Royal Observatory and Cutty Sark, with the surrounding streets in the buffer zone. That means townscape and setting weigh heavily on how schemes are assessed. We check exactly which conservation area — and which Article 4 direction — applies to a Greenwich address before advising on a permitted-development or full-application route.
Planning in Greenwich (SE10): what to know before you apply
Most SE10 houses fall inside the West Greenwich, Greenwich Park, East Greenwich or Ashburnham Triangle conservation areas, and the first three carry Article 4 directions removing permitted-development rights for re-roofing, windows, doors and other external changes. The Maritime Greenwich World Heritage Site and its buffer zone add further townscape scrutiny. We confirm the conservation area and Article 4 status for a specific property before recommending a route and drawing to the Royal Borough's guidance.

Structural Drawings for Greenwich (SE10) homes: the package and the process
Every structural drawings we prepare for an Greenwich property is drawn to Royal Borough of Greenwich’s validation standards and tuned to the SE10 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Structural drawings and calculations are the technical backbone of almost every London home improvement — removing a wall between a kitchen and dining room, inserting a steel beam (often called an RSJ) to open up a room, digging foundations for a rear extension, or checking that an existing roof and floor can safely carry the extra load of a loft conversion. Building Control will not sign off any of this work without a calculation from a qualified engineer showing the beam, foundation or floor is correctly sized for the loads it carries, and most builders will not order steel or start groundworks without one either.
DrawingsDirect produces and coordinates structural calculations in-house alongside your architectural drawings, rather than treating them as a separate, disconnected step. That matters in practice: it is common for a beam size on a structural calculation to not quite match what is drawn on the architectural plan, which causes delays at Building Control or confusion on site when the builder is ordering steel. Because we draw the architectural set and coordinate the structural calculation together, the beam, padstone and bearing shown on your drawings are the same ones the calculation is based on. Structural drawings are available as a standalone service for a single wall or beam, or bundled into a larger extension, loft or basement building regulations package.
Do I need structural calculations to remove a load-bearing wall in London?
If a wall carries any load from above — a floor, a roof, another wall, or a chimney breast — you need a structural calculation before it can be removed, and Building Control will ask for it as part of a Full Plans or Building Notice submission. This covers the great majority of kitchen-diner knock-throughs in London terraces and semis, where the wall between the kitchen and the rear reception room is almost always load-bearing. A calculation confirms the size and type of steel beam needed to replace the wall's support, the padstones or pier that carry the beam's weight down to the foundations, and the temporary propping needed while the work is carried out. If the wall shares a boundary or the new beam bears on a party wall, the Party Wall etc. Act 1996 will also apply and needs to be dealt with separately from the calculation itself.
How steel beam sizing works
A structural engineer calculates the loads bearing down on a wall from the floors, roof and any walls above it, then sizes a steel beam (RSJ) — its depth, width and steel grade — so it can safely carry that load across the required span without excessive deflection. The calculation also fixes the bearing length at each end, the padstones or steel plates that spread the load into the surrounding masonry, and whether the existing foundations need strengthening to take the extra point loads. Because we coordinate the calculation with the architectural drawing set, the exact beam size, orientation and position shown on your plans is the one the calculation specifies — so your builder can order the correct steel first time, and Building Control sees a consistent set of drawings rather than two documents that disagree.
