Hi Sandra, Being in a marine environment either option you go with will require a bit of maintenance over time the salt air is pretty unforgiving. If you do decide to go with render make sure you go with an acrylic render it will last alot longer and avoid cracking much better than if you go with a traditional cement render only. Generally the cement render is applied and then the acrylic render is applied over the top this makes the cement render a lot stronger and more flexible. You can tint the acrylic render to the colour you wish so if you want you don't even have to paint it. Although some people still apply a bonding agent and paint it regardless. Good luck with your project I hope it turns out great.

If you have a clothes dryer in there you will find that there is a lot of dust attracted to the doors which are then a challenge to clean. I would advise a condenser dryer as it doesn't need to be vented outside and is a little less dusty.

Different manufacturers have different track and sill details. You need to contact the manufacturer of your doors and get a drawing of the section of the sill and track, as well as ask their advice. I would be carefully considering how much water will reach the door frame when it pours with rain (how much protection does the eave offer). It also depends on the existing structure (if you are renovating) and exactly what you are cutting away to lower the door frame. You will run into issues if you have to cut out the edge of an existing slab. I suspect that it is not as simple as you hope otherwise it would be done all the time. So much potential for things to go expensively wrong if you don't plan it carefully to the millimetre. You can see in this photo it is not your standard track, and that a grate to drain water runs parallel to the door to minimise the risk of rain water being blown in. I wouldn't part with any cash until you have worked out all of the little details. It is a general rule of architecture that if something looks flush, clean and seamless then somebody has put a lot of thought into how to achieve that result, and the tradesmen involved have been much more careful, precise and taken their time to get it perfect. All of this costs money.... Best of luck, Dr Retro of Dr Retro House Calls
