Structural alterations, new openings and steel support in Grays. Trusted, professional, 30+ years' hands-on experience.
Structural alterations are the jobs that change how a building carries its load: new openings, beams, chimney breasts, and the supports underneath them. We coordinate the structural engineer, the building control application and the trades, and we build to the design issued. We never produce structural calculations ourselves. This page sets out how that works with Thurrock Council for a property in Grays.

Thurrock Council is a unitary authority, so planning and building control for Grays sit with the same body. There is no county layer above it. That keeps the paperwork in one place where a job needs both a planning decision and a building regulations approval.
The council runs its own building control service for Grays, contactable on 01375 652 655 or building.control@thurrock.gov.uk. We make the application, deal with the officer and book the inspections, so you are not chasing two organisations for a date.
The council's building control notification stages include commencement, foundations, excavations, oversite preparation, damp proof course, steel beams, floor and roof joists, thermal and sound insulation, drains laid and ready for inspection, and completion. A structural job can touch several of those in a fortnight.
Thurrock operates next-day inspections, and asks you to book on or before 4pm to secure a next-day visit. That is workable if someone is watching the programme daily. We hold the booking calendar against our own sequence, so the follow-on trades are not standing still while a visit is arranged.
A Thurrock Council building control plan approval is valid for 3 years from the date the plans are deposited, and the work must commence within that time. If you are approving now and building later, that is the window to work back from.
The council's charges are set on the basis that the work takes no more than 24 months from start to finish, and that the cost estimate excludes professional fees and VAT. So the figure the charge is banded against is the building work, not the engineer. We set the two out separately in the quotation.
Thurrock Council's internal alterations guidance lists both total and partial removal of a chimney breast and stack as work requiring a building regulations application. A breast taken out on one floor only is not a cosmetic job in the council's eyes, and neither is a partial removal.
The council also advises that work on an existing wall or structure shared with another property, and excavating near a neighbouring building, may fall within the Party Wall etc Act 1996 and require notice to affected neighbours. We raise that at the survey. We are contractors rather than party wall surveyors, and we say so before the work is priced.
Structural alterations go wrong at the joins: between the engineer's design, the council's inspection stages and the trades on site. We hold all three. We appoint the structural engineer and build to their calculations, and we never write calculations ourselves. We make the building control application to Thurrock Council, which runs its own service for Grays, and we book the inspections against our programme rather than after the event. Building control applications and inspections are coordinated for you, quotations are free and without obligation, and GS Renovation Ltd is fully insured and registered in England, company number 14611254.

FAQ
Be careful, particularly if nobody has visited. Pricing structural alterations for a Victorian and Edwardian terraced Grays house without seeing it is how a low figure becomes a high one halfway through, and the extras land at RM16 when you have no leverage left. GS Renovation surveys, itemises and holds the total. A second opinion costs nothing and carries no obligation anywhere in Grays. Call 07472 424 226 and we will look at the RM16 quotation with you. As a rough guide, structural alterations in London ranges from roughly £1,500 for a simple opening to £15,000 or more where underpinning or major works are involved (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Thurrock Council has a regularisation route for exactly that, and publishes a separate regularisation charge for removal of a load bearing wall and for chimney breast removal. Regularisation means applying after the event and satisfying the council that the work complies. The council states that where the work was not notified at each stage, it will be required to be cut into, laid open or pulled down so that compliance can be checked. We open up where the officer asks.
Not on our own. A listed building needs listed building consent alongside the usual approvals, and we are a contractor rather than a conservation specialist, so we would ask you to appoint one alongside us. Thurrock Council records 13 Grade I listed buildings in the borough, 19 Grade II star and 212 Grade II. The Dell in Grays is among them, first listed on 27 April 2000. We say this at quotation stage rather than later.
No to both. Thurrock's seven conservation areas are Horndon on the Hill, Corringham, Orsett, Fobbing, Purfleet, West Tilbury and East Tilbury, and none of them is in Grays. The national planning data platform holds those seven records for Thurrock Council and no Article 4 direction record at all. Listing is the designation that still bites wherever a building sits, so we check the address against the list before anything is ordered.
It matters as soon as new load reaches the ground. British Geological Survey mapping records Worked Ground at points in South Chafford, the Grays Thurrock ward and West Thurrock, and Infilled Ground at points in South Chafford, West Thurrock and Chadwell St Mary. Thurrock Council warns that where the loading on an existing structure is to be increased, it may be necessary to expose the foundations, beams and lintels for inspection. That means a trial hole, not an assumption.
Thurrock Council takes both, and they differ in when the design is checked. A building notice starts the work without approved drawings, so the detail is judged on site as it goes in. The full plans route is charged in two parts, a plan charge and an inspection charge, and the drawings are assessed before anything is opened up. Full plans suits work where the engineer's design needs agreeing first. We choose the route with you and make the application.
