Building Control technical drawing packs
Building Regulation Drawings in London for Extensions, Lofts, New Builds and Conversions
Technical plans • Construction sections • Structural coordination • Initial survey within 48 hours

WEDRAWPLANS prepares Building Regulation drawings and technical drawing packs for homeowners, developers, landlords and commercial clients across London and surrounding M25 areas. We help turn approved planning drawings or agreed design layouts into practical construction information suitable for Building Control review, builder pricing and site coordination.
The technical stage needs more than basic plans. A strong Building Regulation package should explain wall, floor and roof build ups, structural openings, insulation, fire protection, ventilation, drainage, junctions and other practical details that affect how the project is built.
Whether you are preparing a rear extension, loft conversion, new build house, conversion to flats, commercial alteration or internal structural change, we can review the scope and prepare a clear Building Regulation drawing package for the next stage.
- • Extension Building Regulation drawings and Building Control packs
- • Loft conversion technical drawings, stair layouts and roof build ups
- • New build, conversion, commercial and mixed use technical packages
- • Structural engineer coordination for beams, padstones and openings
- • Construction sections, insulation notes and practical build details
- • Support for London borough projects and surrounding M25 locations

Drawings prepared for practical construction clarity
A technical pack should help Building Control, structural engineers and builders understand how the project is intended to be constructed, not only what the finished design looks like.
From planning approval to technical package
Building Regulation drawings prepared for approval, pricing and the build stage
Planning drawings usually show the approved appearance, layout and scale of a proposal. Building Regulation drawings go further by explaining how the project is intended to be constructed. They provide sections, build ups, construction notes and technical coordination so the design can be reviewed and priced with more confidence.
This stage is especially important where there are structural openings, steel beams, flat roofs, loft floors, insulation upgrades, drainage changes, fire safety requirements or complex junctions. A good technical pack can reduce confusion between drawings, calculations, builder pricing and Building Control comments.
Extension Building Regulation drawings
Technical packs for rear extensions, side returns, wrap around extensions, internal openings and structural alterations.
Loft conversion technical drawings
Dormers, mansards, hip to gable layouts, stair positions, roof build ups, insulation notes and fire safety coordination.
New build Building Control packs
Detailed technical information for small new build residential projects, construction sections and coordinated drawing packages.
Conversion and commercial packages
Technical drawings for change of use, flat conversions, mixed use alterations, commercial fit outs and structural reconfiguration.

What the technical pack can include
Plans, sections, build ups and notes for Building Control and construction
The exact content depends on the project, but most Building Regulation packages need a clear set of coordinated drawings and written notes. The pack should make the construction approach understandable to Building Control, the structural engineer, contractors and the client.
Projects we regularly support
Building Regulation drawings for residential, commercial and mixed use projects
WEDRAWPLANS prepares technical drawing packages for a wide range of project types across London. The package is adjusted to the actual scope, site conditions and construction requirements.
House extensions
Rear extensions, kitchen extensions, side returns and wrap around extensions where the approved design needs a clear technical construction package.
Loft conversions
Dormers, mansards, hip to gable roofs, stair layouts, roof structure changes, insulation build ups and fire safety information.
Internal structural works
Removed walls, new steel beams, enlarged openings, padstone coordination and drawings for altered internal layouts.
New build houses
Technical drawing packs for small residential new build projects, coordinated with structural and consultant information.
Flat conversions
Conversion drawings for self contained flats, internal layouts, fire separation, sound requirements and technical coordination.
Commercial works
Technical drawing support for fit outs, mixed use buildings, change of use projects and commercial building alterations.
Technical coordination matters
Structural engineer coordination is central to a good Building Regulation pack
Many Building Regulation packages need to align closely with structural engineer information. This may include steel beams, padstones, load paths, new openings, roof alterations, floor strengthening and connection details. The drawings are most useful when architectural and structural information are coordinated clearly.
How we move the technical stage forward
Clear process from review to Building Regulation drawing package
Every project starts with a review of the available information. If planning drawings already exist, we check whether they are suitable to build from or whether further coordination is needed. We then agree the technical drawing scope and prepare the package in a structured way.

Building Regulation drawing questions
Frequently asked questions
Do I need planning approval before Building Regulation drawings?
In many cases, the planning route comes first where permission or lawful development confirmation is required. Once the planning position is clear, the technical package can be prepared for Building Control and construction. Some internal alterations may not need planning but can still need Building Regulation approval.
Can you prepare Building Regulation drawings if another designer prepared the planning drawings?
Yes. We can review the approved planning drawings or existing design information and prepare a separate technical package, subject to the quality and level of information available.
Are Building Regulation drawings useful for builders?
Yes. A good technical pack should support both Building Control review and construction pricing. It gives builders clearer information on build ups, structure, sections, junctions and key details.
Can you coordinate with a structural engineer?
Yes. Many projects require structural calculations, beams, padstones and structural notes. We can coordinate the architectural technical drawings with structural engineer information where required.
How quickly can you start?
We can usually review the project quickly and arrange an initial survey within 48 hours in many cases, subject to access and availability. The drawing programme depends on the project size and information available.
