Here's an update on the work. I've finished the pebbledash first coat, and the painter did the fascias, soffits, door and window. The green I chose came out a lot darker than I thought, but never mind. What do you think? What's left to do is add some nice pots in front, put up the guttering (I'm going to do that now), another coat of the white masonry paint, and of course the most important part, put a cat image in the window!

Changes of fenestration such as changing the shape of the arched window will require planning approval so you should probably decide on everything you intend to do and then make an application. Designers, Architects and architectural technicians can all help here- I would expect them to be showing you in CAD how the house could look. How far you go depends on the available budget. In my opinion the house could benefit from swapping the current leaded light windows for something simpler. Your current windows are not very deep and and the fan lights exaggerate that so perhaps replacements without might be better....and these could look great in all the colours you suggested- personally I just like to see a contrast with the brick so would rather see a light colour choice with this brick. I would probably choose sage green. In my opinion the front door looks undersized next to the big arched window but painting the door and side panel the same colour will make it look bigger. Also I wonder if you are thinking about changing the arched window because it is sitting uncomfortably next to the window next door..... perhaps it is the window above the door that is wrong...... in fact if that is a bathroom and you could get away with a skylight instead I think I would rather leave the arched window and block up the one above the door. However for me the 1950s proportions of the windows slightly let down this house and the suggested full height windows of the garage conversion seem out of place too. If you have the money for a full facelift I would be looking for your CAD expert to show you how the house could look with different shaped window apertures- for instance the two windows to the left of the front door in my opinion would have more presence if they were deeper and fanlights would also work better then. The window above the front door seems too wide and too close to the corner and should relate more to the window next to it that is currently arched- perhaps get rid of this door above the front door or perhaps make it narrower. In my opinion continuing the garage roof towards the front door and building forward the ground floor window to the right of the front door would unify the garage extension with the main house and make it easier to choose a window style for the garage conversion as you would then likely choose three matching small windows. I might even consider making the window of the room over the garage a little narrower. However the room over the garage is a later addition and does illustrate that it is possible to match these bricks so using render to cover your changes may not be necessary and I agree that the brick and the climbing plants help make this a pretty and traditional looking house and unsympathetic changes could ruin that feel.

It's a really nice colour. You may need to go the next shade up as colours tend to be a couple of shades lighter on the exterior but it depends what you like. I'd get some testers. If you're painting directly on the wall you'll need to paint out some of the yellow with white otherwise it will distort the colour. Paint large samples using a min of 2 coats on each side of the house so you can see how it changes. I saw your comment on the other post earlier, I'm finally in the middle of having mine painted (3 years on!). I actually ended up going for F&B colours in the end but colour matched to Johnstones everywhere as it was just too dear other than for my front door which will be in LG.

Keep the bottom half as brickwork. Don’t make the mistake of making it too plain. My neighbour opposite me has a similar style house. When they purchased it they knocked off the render and beams and re-rendered it and left it white. No beams. It has modernised the look. I have timber windows. If you keep on top of the maintenance it’s easy. We have ours done every other year. A quick sand down and re-coated. Easy job for a decorator. Two days maximum work. Most of the houses in our road have UPVC windows. They don’t look as nice as timber. Two decided to have green which looks awful. Really doesn’t go with the style of house or the colour of the brickwork. If you do decide on timber windows personally I would steer away from Georgian design. That’s now dated. Nobody asks for them any longer, neither do they ask for leaded windows (i’m a partner in a joinery company and nobody ask for this any longer). I would also be tempted to keep the timber windows natural as opposed to painting them white. It’s far easier to maintain with a stain/sealant as opposed to sanding down old paint. Timber windows all the way for me. Just keep up to date on the maintenance and it’s not a long job.
