Structural alteration in Tring runs on two tracks at once: what the structure needs, and what Dacorum Borough Council will consent to. The conservation area brings extra control to the addresses inside it, and permitted development rights have been withdrawn at named properties on top of that. We appoint the structural engineer, build to the calculations, and coordinate the building control side.
What consent a structural alteration needs here
It depends first on whether the address sits inside Tring conservation area. Dacorum Borough Council designated that area on 6 October 1969. The boundary was reviewed and amended on 16 February 1978, and a further amendment was adopted on 27 November 2019, so an old plan is not a reliable guide to where the line runs now. Historic environment policy sits in Dacorum's Core Strategy of September 2013, at Section 17, Policy CS27.
Inside the boundary, work that would be permitted development elsewhere needs an application. We check the boundary position for the specific address before anything is priced.
Article 4 in Tring is a schedule of addresses, not a rule for the town
Dacorum's Tring appraisal states at section 9.0 that Article 4 directions withdrawing permitted development rights already exist at 1 to 18 King Street, together with Hamilton House, Kosicote and Hope Cottages. The same section lists numbers 94, 96, 102, 104, 106 and 108 High Street, and Linwood and Farleigh in Park Road.
The council's own published Article 4 directions page tells a different story. The only direction it lists for Tring covers land at Icknield Way, made on 15 July 2022 and confirmed on 21 November 2022. Two sources, two lists, which is reason enough to check your own address against both rather than assume the position from a neighbour's job.
How much designated fabric sits in the conservation area
Appendix 1 of the Tring appraisal states a total of 54 statutory listed buildings inside the conservation area, although the schedule itself sets out 55 separate entries, several of which cover more than one property. The parish church of St Peter and St Paul is the only Grade I listed building scheduled there. The Clock House and The Mansion on Mansion Drive are the only two listed Grade II star.
Listed building consent is a separate application from planning permission, and it reaches internal structural work. We are contractors, not architects, surveyors or heritage consultants, so where a listed building is involved you appoint the right consultant and we build to what is approved.
The ground is not the same across the town
The bedrock formation changes within Tring. British Geological Survey 1:50,000 mapping gives the Zig Zag Chalk Formation beneath the High Street, Akeman Street, King Street, Western Road, Park Road, Miswell Lane and Station Road. At Icknield Way on the northern edge it gives the West Melbury Marly Chalk Formation, an older and marlier chalk. The superficial deposits layer returned no polygon at Akeman Street, King Street, Western Road, the west end of Park Road or Miswell Lane, so chalk is mapped at the surface there.
Where an alteration puts new load into the ground, the foundation is designed from what is found on site. Underpinning, new pads and widened footings are all engineer's work, and we build to the design rather than around it.
- Steel beam and RSJ installation
- Load paths carried down to foundations on new piers and pads
- Lintel replacement and repair over failed openings
- Trial holes to confirm foundation depth and ground conditions
- Crack repair, helical bar stitching and masonry restraint
Why Choose GS Renovation in Tring
Structural alteration in Tring turns on the address as much as on the structure. The conservation area boundary has moved twice since 1969, and permitted development rights have been withdrawn at named properties rather than across whole streets, so the position at your house is something to check rather than assume. We appoint the structural engineer and build to the calculations they issue. We never produce structural calculations, and we hold no trade body accreditation. We are fully insured and registered in England, company number 14611254.
- Work sequenced around the surveyors' schedule of condition before excavation
- Underpinning carried out in sequenced bays, never one long trench
- One point of contact on the phone, not a call centre
- Registered in England, Companies House no. 14611254
- The engineer's calculations obtained and worked to on site
- A dedicated project manager from first survey to handover
