whatever you do.. get lots of quotes.. the difference on just timber was around £1200. Good luck!

It depends on the material used. eg 9x3 floor joists are big and cost alot more when you compare them to 8x2.. all in all.. I would be tempted to say.. to finish off add another 3/4k ontop.

nice!

as much as I like the idea.. I dont even see any structural timber used! be-careful i wouldst be lifting under that.

Update from last few weeks of work! Dormer 1 insulation has been inserted. Ceiling level is complete... through out the entire loft have a few more bits of wood to measure up and deploy. Timber bolts in to hold everything in tight. (I dont see the point as i cant see a 8x3 @ 6 meters moving on...

more pictures.

It was hard work getting the RSJs up. Only took pictures of the floor and nothing really of the dormer construction... but it is not easy work! The timbers you work with are pretty heavy and require multiple hands!.

Are the pictures wonkey it are the walls bent?

If you want my advice go for a steel, In order wise when I had it installed.. - It was two sections, had it winched around the outside of the house onto the scaffolding. - Brick work was notched through and the RSJ padstones installed. (at this point the tiles were stripped off the roof and...

Well guys, I live in a semi detached house that had a hip roof. I had a conversion to a gable end and have been working slowly on the insides on the past few weeks. I am going to try and do as much as I can DIY apart from gas and electrics. My latest update is the ceiling I am installing...

Timber beam wont fit, I tried this with my loft conversion. It just doesn't happen! The timber beam will become too big to handle.

Hello guys I am doing a self-DIY conversion on my loft and I have two dormers. It mentions I need a U value of 0.28 "270mm Fibre Glass in Roof Space" Min Value 0.18" It then mentions Dormer Cheeks of PVCU Clanning, 12mm External Ply wood, 100x47 Framework. Rigid Insulation to Maintain Value...

expensive. £1064 They worked out to be around 28£ per joist, I used 38 of them, but ordered 44. 6 of them were cut by the builders and used as structual support for the roof whilst the old purlins / hip was removed :(

A lot of history, originally the timber joists were designed to sit on the external wall and the internal load bearing wall. However this couldn't be done due to the way the roof came down onto a purlin and then the eves cut across at an angle. To keep the roof design it was decided later on...

Its the span of the room hence why I need to use 9x3 Joists. :( The roof has been re designed to sit on 4 RSJ's which span the length of the house. I could use long brackets to hold the roof eves to the new wall plate. (which will need to be done anyway) lets hope my inspector is happy...
