Here is the start of Erdinwood Resort Mansion. It’s the lot right near the Old and New Glam household.
In this picture, it is finished. Inside I have created a mini recording studio, three bathrooms, two bedrooms side by side, a study, a living room with an open plan kitchen to accompany it and a pool with windows. I hope you liked it. If you would like me to build some more houses on the Sims 3, then please put the name of the house, a custom theme (optional) and a name for the house in the comment section. Thank you!
