Ok, donc tu peux écrire:
A lot of effort has been put in to make the house a better place to live in.
Many things such as the fence, the front door and the roof have been repaired and retiled. The house itself has been painted and the grass has been cut, making it look nicer. The interior of the home has been modernized. For example, central heating has been added and modern touches have been made in the bathroom.
Voilà, j’espère que ça t’aidera !
