Renovators who end up in a legal dispute with their builder could find that legal fees and repairs cost them more than the renovation, building industry experts have warned.
On the other hand, being prepared and having everything specified in writing will go a long way towards diverting many disputes, according to Edward Lukac from Archicentre, the building advice service of the Australian Institute of Architects.
Disputes with a builder about renovation work or new home building are usually over one of three main issues - the scope, completion or quality of the work.
Mr Lukac pointed to the increasing number of new home buyers and renovators appearing on current affairs shows across Australia, often standing in ruins of half-finished or badly-constructed buildings.
"The majority of these disputes relate to a lack of preparation and a communication breakdown between parties over what was included within the price, what wasn't included and how much more the 'extra' work is going to cost", he said.
"The arguments usually result from a lack of clarity at the very beginning of the project when quotes were being obtained, where owners have not presented accurate plans, nominated required finishes or specified the quality of fittings, leaving the builder to guess."
Mr Lukac said that in order to get a firm, reliable price for your renovation project, it is essential to put some time and effort into specifying everything you want, right down to the type of door handles, the number of power points and the size of the kitchen sink as fittings can be extremely expensive items.
"The completion of works within a set date depends on a number of factors relying again on a good, clear understanding between client and builder of the project start and finish dates, regular attendance onsite by the builder and prompt payment of invoices by the client.
"A written contract confirming these particulars is a must and the role of the architect is to ensure their client's interests are protected."
Mr Lukac said that differences of opinion over workmanship quality are the source of many an argument, but there are published guidelines that take the guesswork out of whether something is acceptable or not.
"Regular inspections are necessary to ensure that poor work is picked up and rectified early and whilst it is up to the builder to check the work of their tradespeople, if you want independent 'third party' inspections an architect can assist with these as well.
"Successful, dispute-free building projects rely on teamwork so having an architect on your team can make all the difference."
