Firstly indent the text - it doesn't look right inline with the frame border.
Secondly more information, there's no story there except the "look, it's a house". Make that sentance the heading for the front page, and put the stuff on the 'About Us' page as the content for it - stick some emotion into there, why you are undertaking such a massive challenge as opposed to just stating that you are.
On the "About Us" page I'd have two passport-type photos and write who you are, your interests relevant to the project etc - look at the iWeb templates for ideas on what to put there.
Remove the front gallery page and instead have it go straight to pictures with headings instead of the navigation bar on the left - at one stage I can see three different navigation bars on one page. When you click on a picture make it appear in a new window, smaller, not taking them away from the original page like it does now (and the pictures are too big even for my 20" display - 1200x1060)
Finally swap around the gallery and contact us page, and either have the contact us page aligned to the right of the top nav bar or remove it entirely and include the info on the about us page.
Basically at the moment it's too big for the content it has - reduce the page count.
