I have just bought a pre-owned linked bungalow. The previous owner renovated and extended it 2 years ago, and generally the house is in a pretty good condition. But I still need to do some renovation - looking at:

- painting entire house
- garden landscaping (considering changing car porch tiles and converting some tiled portion to grass)
- changing all toilet floor and wall tiles and toilet seat covers
- electrical check
- pumbling check

and on top of that looking at some ID for house interior.

I have not done any reno before, so I have no clue where to start. Do you think I should attempt to do this on my own or enlist someone to help out e.g. ID or contractor?

it is the same as semi-d but linked at the back of the house instead. so there is garden on both sides of the house.

Are there contractors who are able to help give advise on interior design as well?
