This is a job I've been working on in the evenings and weekends for the last month or so. I've changed most of the doors in the house and the two front doors.
It's amazing the difference changing the front door and painting the windows has made to the front of the house. Certainly improved it's curl appeal!
I changed most of the internal doors for oak as well, and I made a couple on site for the cupboard under the stairs. Architrave and skirtings were also changed for oak in places as well. I treated them all with a coat of Osmo oil before leaving them.
Hopefully all this work will make the house more appealing to potential customers.
