Ok, how does the attached look?

Option 1 is the traditional wall plate utilising a joist hanger.

Option 2 is where there is no joist hanger and the joists are sat ontop of the wall plates

Option 3 is where a wall plate is bolted onto the face of block or brickwork and then a joist hanger is used.

There are also other options but these are the most common. Personally I would use either option 1 or 2. Option 2 is good as long as the resultant floor levels are not put too high i.e. requiring steps to get into the obsy and or increasing the overall height.

Hope that help?

Sort of, give me a couple of minutes and Ill sketch what I mean

Looking at that sketch I might be tempted to put the joist hanger on top of the sole plate.

Normally a wall plate will be used to bear any kind of joists either by a joist hanger or directly. The wall plate (or sole plate in this case) will be bolted down to your block work allowing the the load to be distributed more evenly.

I would personally build the studwork off your brick walls rather than off the floor.

I would feel more comfortable knowing that my sole plate was fixed to the brick directly.

Looking good and pretty much how I would do it as well. As for the pier my personal preference would be for a steel pier over concrete. That way if you move house you can take it with you. Plus it gives me something else to design for my hypothetical obsy.

Another great read. Im definitely gonna start designing my obsy now

With regards to planning permission being required, this can vary depending on your given situation. If in doubt I would strongly advise that you contact your local planning authority who will let you know if planning permission is required.

Having said that, a little advice below:

If you are on whats called designated land (Site of Special Scientific Interest (SSSI), a Conservation area or World Heritage Site, an Area of Outstanding Natural Beauty (AONB) to name a few) then you will need planning permission for what would otherwise be allowed under permitted development rights given to land owners under the General Permitted Development Order.

Have a read of this:

Planning Portal - Permitted Development Rights

And this:

The Town and Country Planning (General Permitted Development) (Amendment) (No. 2) (England) Order 2008

Generally we are looking at Class E - something which is incidental to the enjoyment of the occupants of the dwelling house.

Providing the following rules are met then you should be ok - however, if in doubt seek professional advice.

1. The new building or enclosure, together with all existing buildings (including the dwelling house) must not be greater than 50% of the land.

2. It cannot be built foward of any principle elevation formed by the dwellinghouse

3. Must be single story.

4. There are limits on height - 4m for a dual pitched roof; 2.5m if it is within 2m of the boundary; 3m in any other case.

5. Any eaves must be no higher than 2.5m

There are other rules that apply so please read the full section, but the ones listed above are the main points to consider.

There are numerous ways of creating the final image, use whatever you find easiest. ICE can do a good job, as does iMerge.. they are free, there are many others that are pay to use.

A great read, now Ive finally got round to it!!!

Just a thought for the masses, but how about merging in photoshop to create the mosaic once all the images have been registax'd? I know CS2 and above the photomerge function works extremely well.

Just thought I would say that this forum is amazing. Everyone is so friendly and helpful.

Im on the verge of getting my first serious purchase and members have been so helpful and instrumental in that.

I dont think there is any thing I would change at present and just want to say a big thankyou to all :-)
