I don't think that you will have a problem without building a study........ The extra garage space will be a valuable asset...........and can do double duty.....

Without looking it up , the new Credit Regulations came in on 1 Dec , and there is a fine of up to $200,000 for every instance of 'irresponsible lending' . The problem seems to be that it isn't defined . So a couple who have been together for 5 years , saved $100k , both on $100k plus , have $50k of cars that they are prepared to sell and drive $5k ones , plus 1 lot of parents has $50k to lend them . A house that is $1million they can afford . But what if the female gets pregnant ? What if he loses his job and takes 2 months to get a $50k job ? What if the parent dies and the lawyer wants the $50k back ( or $37.5k of it to distribute to other siblings ) ? Those clothes trucks that go around the lower income suburbs sell a pair of 'knock-off' designer jeans to a solo mum for her 14 year old daughter . They charge $5 a week for 20 weeks , mum and daughter are happy because it fits their budget . You and I can probably find them on-line for $40 , they might be able to too , but to get $40 might mean missing a couple of meals or not prepaying the power , so they don't . I am a director of more than 40 companies . Probably half of them I own 99% of shares , others I own 33% or 40% or 50% . Pre-Covid , combined turnover was well over $250k a day , my property holdings are well into 8 figures . In June/July when I bought the Lincoln Street property , the mortgage was almost a formality -- I've dealt with the same bank for 35 or more years , have good cashflow and own a reasonable whack of my properties . Almost all have mortgages , and the more valuable ones also have floating charges , but I doubt I am classed as a risky borrower . Tenders close on this place in just under a month , but as it is technically not livable ( a couple of walls have been taken out and additions started -- they have closed it in with building paper and ply and wrap ) , I cannot get a mortgage , even though my intention is make it better , spend up to $1.5mil , and live there for at least 15 years ( I will have turned 70 by then haha ) . So if I do get it , rather than a approx 3.5% mortgage , I will have to get it via Bridging Finance ( at 11% ) , then after a year or 18 months , when everything is complete and Lake Crescent ( my current place ) is hopefully sold , and hopefully the rules have been clarified , I then go the through process of getting registered valuations and applying for a mortgage etc . Assuming Lake Cres sells for around what everything thinks , even after spending $1.5M on alterations , the mortgage should be under $2M and valuation likely to be around $7.5M ( land and stables etc will make up about half that ) , but right now its harder to get that than it was to get funding for Lincoln Street , which depending on exactly how it all pans out , will be $15M plus when complete . Interesting couple of months . This is a picture taken from a spot towards the rear of the property -- a bit clearer than the other ones .

my suggestions has the central entry and a small study off the living room...(twin desks provides more counter and wall storage and avoids sitting face to the wall) there's a generous laundry mudroom with direct external access, a bathroom with separate powder room, more space in the master suite with the window offsett for furniture and more privacy from views across the courtyard and reversing the wiw and ens allows for morning sun in the shower and the wiw creates a sound barrier against the guest room.. adding furniture helps suggest room sizes and there's various setdown spaces and extra storage throughout the house ...luckily there's plenty of room for more than minimum offsets to create a garden, alfresco, courtyard, screened spa room, entry, kitchen and laundry porches, garden sheds and drying areas and careful choice of building sizes allows for a neat gable roof with the extended eaves and a hip roof over bed 3 keeps the whole roof simple and economical to build
