The exact reference to 2023 from TowersTimes:
"The documents submitted refer to the development as having a total construction cost in the region of £12.5 million. When considering the economic benefits of the development, it is stated that 150,000 additional visitors are envisaged due to the opening of the new attraction. Although a specific construction period of 78 weeks is stated, other documents give a more general estimate of 2 years. Therefore, with construction noted as being proposed to start in Spring 2023, this would seemingly put the attraction on track to open for the 2025 season."
It's the last sentence that's rather confusing, but contains the 2023 date. None of the documents submitted, nor any of the documents listed on the TowersTimes page, have a proposed construction start date at all (of 2023 or anything). The last sentence appears to state categorically that construction will start in 2023, but doesn't actually give a source. "with construction noted" is an interesting non-committal phrase here; where is it noted? The paragraph confuses this further because the construction period of 78 weeks - 2 years are actually real proposed construction durations listed in documents that are cited. I can only presume that the phrase "Therefore, with construction noted as being proposed to start in Spring 2023." is making an assumption of construction being proposed to start in 2023 because of previous speculative statements by commentators, an excited community and vloggers.
To me, that would infer that the project may have been pushed back by a year or so.
Construction couldn't have started in Spring 2023 because full planning permission wasn't granted until 22nd June 2023, the second day of Summer.
It's incredibly unlikely that construction on the project would have commenced the first day after planning permission was granted. Demolition crews have to be organised, along with construction crews and then actual purchasing and manufacturing of materials and the ride itself. I doubt that Merlin would have done any of this until planning permission was an absolute guarantee. They'd have had agreements in good faith, pencilled contracts as it were, but they would have been contingent on planning permission being granted.
The speculation that "the project has been pushed back by a year or more" only exists because of the speculation of a Spring 2023 construction start date. The former can only be true, or the case, if the latter is demonstrably true, which it isn't.
- Construction is going to take between 78 weeks and 2 years, so roughly 18 - 24 months.
- Full planning permission was granted on 22nd June 2023.
- Work on the site cannot take place until full planning permission is granted.
- It's unlikely that Merlin would have pressed the "go" button on pre-construction contracts for demolition and manufacturing before planning permission was granted.
There aren't any signs of delay anywhere, but there aren't any signs of progress either. This doesn't mean that the project has been delayed, or scrapped. Correlation doesn't equal causation. We're all extremely good at spending too much time trying to read meaning into our tea leaves, rather than drinking our damn tea.
Project Horizon can't have been pushed back if it was never intended, or even plausible, to have construction start in Spring 2023.
Let's apply Occam's razor here: If you have two competing ideas to explain the same phenomenon, you should prefer the simpler one. Construction hasn't started on Project Horizon because construction wasn't meant to have started yet.
