I/we understand that if I/we reach this undertaking the Council may exercise its powers in relation to the illegal building work and may present this undertaking in evidence to a Court."
30 On 8 July 2004, Mr Purvis of the Council received a telephone call from a structural engineer engaged by the applicant, Mr Anthony Pellicano. Mr Pellicano advised that he had attended the premises. His inspection indicated that underpinning is required immediately and that the Council should lift the stop work order until such time as the underpinning is complete. Mr Purvis informed Mr Pellicano that the Council would allow this work to be performed but would require something in writing to add to the file.
31 Mr Pellicano faxed a letter from him dated 2 July 2004 but received by the Council on 8 July 2004. That facsimile stated:
"I attended the site on Friday 02 July 2004 to inspect the unauthorised excavation work carried out to the subfloor area of 5 Rayner Street, Lilyfield.
In regard to the notice of demand to stop work issued by Council, it is strongly recommended that Council allow the underpinning stage of the works to proceed to ensure the structural stability of the existing structure is maintained.
Once all the underpinning is completed and the structural stability of the existing structure is maintained, then works can cease until the owner complies with all the conditions of the notice of demand to stop work."
32 On 10 August 2004, the appellant lodged an application for a building certificate for works that the appellant described as "underpinning/storage space."
33 On 30 August 2004, the Council wrote to the appellant requesting information, in particular a surveyor's report, and deferring further consideration of the building certificate application until the information was received by the Council.
34 On 1 September 2004, Mr Byers received a survey of the land. However, the survey did not show the area that had been excavated under the floor of the dwelling house.
35 On 22 September 2004, the Council again wrote to the appellant requesting further information, this time a structural engineer's design and certificate for the excavation works to be carried out beneath the dwelling and a structural certificate of works undertaken to date. Again the Council advised that it had deferred consideration of the building certificate application until the further information was received by the Council.
36 The appellant claimed that he never received this letter.
37 On 16 November 2004, the Council again received a complaint from a neighbour about building works being undertaken by the appellant on the land. The neighbour complained that excavation, movement of bricks and other building materials, drilling and hammering were taking place. The work was occurring at all hours of the night, during the week and weekends.
38 On 16 and 19 November 2004, Mr David Morley and Mr David Shaw of the Council visited the premises but no one was home.
39 On 29 November 2004, Mr Morley inspected the premises and observed that no further work seemed to have been undertaken since the undertaking was signed to stop work.
40 On 9 September 2005, representatives of each of the Council and the appellant attended the appellant's property and prepared a sketch map of the excavated area and took photographs. The sketch map showed the dimensions of the excavated area to be, at their greatest, 6.5 metres by 8 metres. The photographs showed that a concrete slab floor had been poured in part of the excavated area, brick walls had been built on the faces of the excavation, a door frame entrance had been installed and a staircase had been built from the entrance to the floor. The photographs also show electrical wiring. These items of building work appear to have been done subsequent to the offence period in June 2004, as they do not all appear in the photographs that were taken on 23 June 2004.
41 On 14 September 2005, the appellant's engineer, Mr Pellicano, wrote to the appellant stating:
"Having inspected the excavation of the subfloor area to the existing premises on 12 September 2005, along with the underpinning works being carried out, I am of the opinion that the structural adequacy and integrity of the existing structure has not been diminished.
