Can you refurbish your house with a residential mortgage?

Depending on layout you could be more creative than just knocking down a wall.

What benefit from making the bigger room even bigger?

eg. Could set it up as a walk in wardrobe with or without a new door into the main room.
(converting back very easy if done using stand alone fittings)

Creates more space in the main room removing the need for clothes storage might achieve what you need /want

We use ours as a office space so none of that stuff needs to be elsewhere in the house.

The bigger room may not be big enough, in fact of the hundreds of bedrooms that I've seen in my viewings I would call "master bedrooms" only 2-3 of them. For me anything smaller than 4.5m x 3.5m is just not fit for my purpose.
I need to have ample space to move freely all around the bed, and not only in the main bedroom: in all of them, even at the cost of having one or two less bedrooms.
If I look at the layout of the typical house in London I always think that I would knock down the wall between the front facing bedroom and the boxroom and I would enlarge the other bedroom retreating the wall in the master bedroom, so as to have 2 equally sized bedrooms (with the master facing the garden instead of the front).
The underlying idea is
- wasted space
+ private space

Now I'm living in a  big-gish bedroom (the landlords call it a double bedroom, but since it's 4.35x2.65 for me it's a wide single bedroom) with an office corner. For me it's much better than having a small bedroom and a tiny office because I never feel the sense of claustrophobia.
If a house isn't comfortable for me, what's the purpose of buying it?
