I like it! Very bold statement

Sorry to dampen your ideas about changing your home but I think it is a beautiful home, in no need of any changes at all, in my opinion! It is a picture perfect home with a lovely low maintenence garden and beautifully presented. I would not have bought the home personally, if I wanted to make the amount of external changes as you are thinking of, perhaps instead, use this home as a stepping stone and buy something already more like what you are dreaming of owning or accept the beautiful home you already have, again in my opinion of course!!

EASY INSTALLATION DECO’s timber look aluminium building products are available as simple do-it-yourself installation systems, that can potentially save home owners a lot of money on their building or renovation project. DECO’s systems such as DecoDeck, DecoSlat and DecoBatten are designed for minimal tooling and expertise. Installation instructions are available for download from the website that come complete with helpful diagrams and handy hints. LIGHTWEIGHT One of the key benefits of building with aluminium is its lightweight composition. Hollow aluminium profiles are available in large extrusion and therefore specified without any excessive weight. The density of timber varies but it can be harder to install and require extra labour due to its weight. Aluminium’s lightweight advantage results in substantial reductions in installation times and labour costs. ONSITE CUTTING Due to aluminum being lightweight and thin, it can be easily cut down into any length required for your project. Are you considering cutting your own aluminum? The answer is you should. It will benefit you and your project (i.e. Decking) and is as easy as cutting timber. All you need is a mitre or drop saw with an aluminium blade, and some protective gear. Did you know…DecoSplash splashbacks can be delivered cut-to-size, however DECO recommends cutting your splashback on site to allow for adjustments that may be required. Aluminium blades on a circular saw is ideal for cutting long cuts and a metal cutting blade on jig saw is suitable for cuts outs. From there your splash is easily installed with an adhesive. ACCESSORIES System components and accessories can be supplied by DECO to ensure your product is installed perfectly and finished off neatly without additional labour and material costs. DECO accessories can come colour-matched to your desired project colour, giving your cladding, battens, slats or deck a seamless timber look all the way round. DECO’s products such as DecoClad, DecoDeck and DecoBatten are simple systems that are installed quickly and easily as well as offering a concealed fixing for a perfect seamless finish. The DECO range is an easy and effective solution that does not compromise on quality.

To be honest I think you're better off looking at the style of house you have.  Deciding what you like about it and finding a style which suits that kind of house.  I'm not a huge fan of Hamptons but if I lived in a Queenslander or just a weatherboard cottage in a regional area that's probably what I would choose.  My current house is 1960s and so better lends itself to modernist but our extension is quite contemporary and has been styled to match.  Previously I lived in a federation house and my decor was different again.  My other tip is to look at your wardrobe and at outfits you really love and why they work.  I think this gives you a good idea of colour schemes and styles which would suit you.  I'm no interior expert but you can then find pictures you like and build up on Houzz or Pinterest. You don't really need a name as such as this just becomes marketing. For example Kate Walker Design's KWD demonstrates some different design styles but I like most of them equally and would again make choices based on location and the style of house.   Sometimes it's easier to simply rule out what you don't like (for me that is primary colours and shiny surfaces)
