I agree, new front door, and some planting. The main problem is that everything is unrelieved red-brown! walls, windows, door, drive. Except the garage door, which then looks like a mistake! This is a common problem. You need to break up the brown. Render or cladding is probably overkill, there are more subtle solutions. Please don't put in an oak or stained timber door. It might look great in its own right, but will just be changing one brown for another! A painted timber (or composite) door would be best, with the garage door painted to match. Choose a shade of grey or green, avoid red and purple, as you need a good contrast to the brick. Ideally change the windows to cream, or grey-green, but if not, try the shutters. They are a bit 1960s, but might actually suit the style of this house! Painted to match the doors. Consider taking up some small areas of paving near the house to allow planting to create a break between the brick drive and the brick house!

If you were our client, we would first assess which way the house faces in order to understand the direction of the sun and the likely impact on the space in terms of light and heat, plus we would ask what use you intend to place on the new space. It is also the case that with whatever heating - a fully glazed conservatory can seem an inhospitable space in the winter months. Even in the UK heat gain during our short summer is a major consideration and whilst roof blinds can be added - these can spoil the original design intent. A part solid / part glazed roof with fully glazed walls may be the most successful. Attached image of a garden room with a large strategically placed roof light and two fully glazed walls.

I love this house. I'd suggest keeping the front door recessed. That little bit of shelter over your head will be useful when you or your guests arrive and it's raining.. You've had some great suggestions.

I'd go mad with some sort of dark olive green and black windows, but it would be a bold choice and definitely not for everyone. We did a dark grey with black windows at the back of our last house and it looked good, though. The top half our Victorian house is pebble dashed and we are restoring the yellow stock brick on the first floor and will be painting the pebble dash something interesting, probably that olive green. That with black windows and dark green front door will look traditional with a contemporary twist. But as I said - far from the normal neutrals!
