Drone Surveys

Drone Surveys

We have achieved our Civil Aviation Authority (CAA) approved Drone License. Along with being fully insured, we can provide roof, chimney, historic building, and many other drone surveys. With its high-tech camera, a drone survey gives you the opportunity to inspect structures at high level in detail without expensive scaffolding or other access arrangements.

Planning Applications and Building Regulations Submissions for Residential Projects

Planning Applications and Building Regulations Submissions for Residential Projects

As a homeowner, unless your project falls under permitted development, as a minimum you will require a planning application followed by building regulations approval. We provide a full Planning and Building Regulations Approval package to get your project off in the right direction. The Planning Portal has a handy and easy to use guide to whether your project needs an application. [https://www.planningportal.co.uk/permission/interactive-guidance]

Listed Barn Renovation

Listed Barn Renovation

This historic barn renovation included traditional slate roofing works, first floor strengthening and reconstruction of historic doors and windows.

Measured Building Surveys

Measured Building Surveys

The basis for most projects is a detailed floor plan of your building, a measured survey is a CAD generated drawing of your building to scale. A detailed floor plan is also a requirement for any planning application.

Listed Building Consents and Conservation

Listed Building Consents and Conservation

Conservation work and listed building applications require an understanding of the impact on historic assets. Retaining and repairing original elements of listed buildings often requires the use of traditional materials and techniques and where modern methods are proposed, the impact on the historic fabric and heritage of the building needs to be considered.

Listed Building Roofing Works

Listed Building Roofing Works

This was a straight forward roof cladding replacement project to a Grade II listed building. Roof repairs do not need planning permission, though Listed Building Consent was required, this included special provisions for retaining historic elements of the roof structure, use of reclaimed ridge tiles and the use of locally sourced slates.

Drainage Design

Drainage Design

This project involved the installation of a new package treatment facility to replace the existing septic tank serving the Tea Room and Public Toilets at the National Trusts Carnewas at Bedruthen site.

Retaining Wall Surveys

Retaining Wall Surveys

Retaining walls are much more complex structures than they look and can be very expensive when they fail. Regular surveys are important in uncovering minor defect which could escalate over time if not dealt with.

Environment Agency Gauging Stations

Environment Agency Gauging Stations

These projects were various river monitoring stations throughout Devon and Cornwall, which required replacement gauging station buildings and associated ducting for river monitoring telemetry. The client wanted to replace the existing dilapidated GRP (plastic) structures with an environmental and sustainable alternative.

Detailed Design

Detailed Design

This project involved a Listed Building application for internal modifications to satisfy various fire risk hazards within the house and east and west wings. This included bespoke fire doors and fire resistant glazed panels.

Weir Engineering

Weir Engineering

This project involved the replacement of the weir crest plate and the installation of an eel pass.

Mine Shaft Cap

Mine Shaft Cap

Cornwall is peppered with historic mine shafts and many of them have been safely infilled or capped. This mine shaft is on the route of the South West Coast path and its cap was in need of replacement. We designed a traditional Clywd Cap to replace the existing one, made of an octagonal steel frame constructed to form a pyramid over the shaft.
