Timestamped, geotagged proof of compliance — captured on site, stored securely.

Part L of the Building Regulations increasingly requires photographic evidence of key construction stages — insulation installation, air barrier continuity, service penetrations, and thermal bridging details. This evidence must be captured during construction when the work is visible, before finishes are applied. Without it, building control can refuse sign-off.

Our client portal includes a dedicated photo evidence module that lets your site team capture and upload photographic proof directly from their Android or iPhone. Every photo is automatically timestamped and geotagged, linked to the specific plot and construction stage, and stored securely against your project record.

This isn't just photo storage — it's a structured compliance record. Each image is categorised by element type (walls, floors, roofs, junctions, services), tagged with the relevant construction detail, and available for your assessor, building control, and warranty provider to review at any time. No more lost photos, no more scrambling for evidence at sign-off.

What needs to be photographed

  • Insulation installation — wall, floor, and roof insulation correctly positioned with no gaps, compression, or missing sections
  • Air barrier continuity — membrane laps, tapes, seals around penetrations, and junctions between elements
  • Service penetrations — pipes, cables, and ducts passing through the air barrier, properly sealed
  • Thermal bridging details — lintels, jambs, sills, floor edges, and other junctions matching the approved construction details
  • Window and door installation — frame positions, cavity closers, and insulation returns as per the approved drawings
  • Ventilation system installation — ductwork routing, MVHR unit position, and terminal connections

Everything you need to manage compliance across your development.

From design stage calculations through to final certification — one platform that keeps everything organised and accessible.

From login to sign-off — how the portal supports your project.

Your portal is set up when you instruct us on a project. From that point, everything is tracked and documented in one place.

1
Project setup
When you instruct us, we create your project in the portal with all plot details, service requirements, and construction details. You receive login credentials and can invite your team.
2
Design stage tracking
As we complete SAP calculations, overheating assessments, and other design stage work, reports are uploaded to your project. You can track progress and download documents as they're issued.
3
On-site photo evidence
During construction, your site team uses the portal's mobile interface to capture photographic evidence of key construction stages. Photos are automatically organised by plot, element, and date.
4
Testing & certification
When on-site testing is complete, certificates are uploaded to your portal. Building control and warranty providers can be given access to review the full compliance record including photographic evidence.

Why clients use the Build Envelope portal.

Common questions about the client portal.

Yes — portal access is included at no additional cost when you instruct Build Envelope on a project. There are no subscription fees or per-user charges. Every client gets full access to project tracking, document downloads, and photo evidence tools.

No. The portal works through your mobile browser on any modern Android or iPhone. Just log in, navigate to your project, and use the camera function to capture and upload photos. They're automatically timestamped, geotagged, and linked to the correct plot.

Building control typically wants to see photographic evidence of insulation installation (no gaps or compression), air barrier continuity (membrane laps and seals), service penetrations (properly sealed), thermal bridging details (matching approved construction details), and window/door installation (frame positions and cavity closers). The exact requirements can vary by building control body.

Yes. You can invite external users including building control officers and warranty providers to view specific parts of your project. You control the access level — they can view documents and photographic evidence without being able to modify anything.

All documents, certificates, and photographic evidence are stored securely for the lifetime of the project and beyond. You can access and download your compliance records at any time — there's no time limit or expiry on stored documents.

Yes. Whether you're using Build Envelope for a single SAP calculation or a full compliance package across a multi-plot development, you get the same portal access. Your project is tracked and documents are available to download regardless of the scope of work.
