Sounds like this house may be a money pit and you are just making new of existing problems and not in the end getting a better result. If the house was in good order and you only needed to knock out say a wall or two to open up the space. Or also possibly replacing the kitchen and bathroom and finally giving the house a fresh coat of paint (inside and out). It may be work considering and speaking to a builder and bathroom/kitchen designer to get prices. But if the house needs much more than this it may be better to look at demolition, (see a builder about this) then rebuilding a prefab or kit home to suit your current and future needs. From my experience any old home that needs major maintenance work completed and also room reconfiguring is a much more expensive project to take on then building something new from scratch. If you do decide to go down the building road, then I suggest working with a good builder who has great communication skills and pick a knowledgeable interior designer that does more than pick paint and tile colours. You need a designer who has a rough idea, (based on past experience and similar projects in your area) of what things cost. Set them a reasonable budget and get them to pull together ideals and concept drawings so your builder can give you a pretty good ball park cost. You can alway pass then next stage onto a draftsman if its not to complicated and work with both the designer and builder to find the correct balance to meet you personal style and a budget.

Hi RJ, There seems to be some dangerously incorrect criticism floating about of using area rates to map out the cost for a project in the early stages, however we can use this to highlight to the Houzz community the appropriateness of using area rates to cost your project in the early stages. RJ you have done everything right in using an approximate area rate to map out your project costs before a designer is appointed!! Although there is some merit to note it is helpful to source your area rates from similar projects from the industry at that point in time - which can be obtained from a QS/Cost Planner/architect/designer - at least you are starting to think in realistic budget terms terms. $2K/m2 may/may not reflect what a builder can deliver for a bespoke design - depending of course on whether structure or kitchens / bathrooms are affected (i.e. check out this amazing kitchen / bathroom calculator from realeastate.com.au!! https://www.realestate.com.au/calculators/renovation-calculator/) ........however this is still getting you close to what might end up being the budget or the revised scope of work. The first thing your designer should do - almost before ANY drawings are done - is check your project budget matches your brief/scope of works by using Cost Plan A area rates and an 'Opinion of Probable Cost".. They can also identify if you are touching other parts of the site or scope that need to be taken into account that you may not have realised. At the start of a project, when there is no design yet, only plans with an approximate area scope of works (floor area schedules), it is what is referred to as "Cost Plan A" stage. Refer to this helpful description from the Victorian Department of Health and Human Services; "Due to the very nature of information available, cost plan A is developed in conjunction with floor area schedules and should be based on data gathered from other similar projects, surveys of existing conditions and major project specific issues such as the suitability, age and condition of existing facilities, including upgrade of site services, asbestos removal, topography, heritage issues and so on."....http://www.capital.health.vic.gov.au/Planning_and_evaluation/Cost_plans/Cost_plan_stages/  One of the benefits of using an architect is that we are rigorously trained and registered to provide "Cost Advice", and right from the early stages using area rates. Building designers must provide this advice however are governed by consumer law and not by an Act of Parliament. When your project is at this stage there is clearly no 'Trade Breakdown" as the design hasn't even started yet!! And yet we must guide you as to an appropriate budget to match your scope of works. A responsible architect / building designer will test these area rates with industry-standard costings to identify an appropriate budget right from the beginning, so that we can make adjustments to the scope to ensure we can get excited about what you can really afford to build before the design is finished. Refer also to this helpful article by Choice on "what can go wrong"......but also what can go right when using an architect/building designer; https://www.choice.com.au/home-improvement/building-and-renovating/design-and-trades/articles/architects-designing-to-build-budget I love that you are already excited to begin looking at a shortlist of Pros in the Brisbane area and I wish you Good Luck!

You could always ask the architect the fees, rather than rely on what your friend says about somebody elses's sevices. I would be very surprised if it was 40% extra. I was recently involved with an interstate project where I could not be on-site. A local architect was engaged for the contract administration. The builder had not had an architect involved with the contract administration before. The architect saved the client tens of thousands of dollars as a lot of work was not up to standard, with the builder cutting corners, and substituting materials, which had to be rectified. This included pouring a concrete slab over a neighbours boundary! This appeared to be their standard practice as they were not used to having their work carefully scutinised, and payments withheld, as part of a contract administration process. At the end of the day I don't know if the builder made any profit, but the client did get the building work that they paid for, so received excellent value from the architect's contract administration services. I am sure that lots of people in Houzz who have horror stories of renovations that have developed problems, sometimes due unforeseen circumstances, and have ended up in a confrontational manner with a builder. There are also clients who have unrealistic expectations about the level of finishes that are physically achievable when working with an existing building (which is never square and perfect). If building work goes wrong it can be very expensive, and confrontational. Engaging an architect for contract administration is like an insurance policy and puts a buffer between a builder and client so things stay civil. The architect can work as a third party to administer any changes and variations that invariably creep into the building process in a fair and equal manner to both builder and client.

Hi, We are looking for an architect practice to design an extension for our house in Dulwich. Ideally the architect would be comfortable working within a budget and also with specific design constraints (an existing Garage that we would like to convert) as well as one who can design an extension that can be completed in stages (so we don't have to move out). We have a builder and are ready to embark on the project so if you can help then please let us know. Regards Adrian
