Introduction
My name is Padraig Donnelly and for the past year and a half I’ve been planning for the opening of a new recording studio in the South Derry area of Northern Ireland sometime in 2009. We’re hoping to start construction at some point within the next six months and we’ve already come up with a few possibilities for the final layout. (Still to come in digital form, but they do exist on paper.)
I’ve been lurking here for a while now and I’ve just recently plucked up the courage to take the plunge and tell you about our project, as well as pose some of our more worrying questions to the community. I’m still a little nervous about posting, but nothing ventured, nothing gained. :)
I’ve also got some pictures of the existing structure. I’d like to point out that these are indeed hosted off-site and not uploaded to the forums, however I have a long standing business account with my hosting company and have no plans to close the account any time soon. In the event that for some reason the account does get closed (such as bankruptcy due to a failed studio venture) I’ll do my best to replace them all within the thread so that they are not lost. ;)
Anyway. Here we go. I hope you like the space.
Budget
The absolute maximum: UK£30,000 (For those elsewhere in the world : US$60,000, €41,000, AUS$69,000.)
Existing Structure

The structure is farm building, constructed over fifteen years ago. It was constructed without planning permission and at the time, it was beyond the reach of Building Control. According to the Planning Authority we have to put in an application for ‘change of use’, but unless we make any alterations to the exterior of the structure we should not need a ‘full application’. Additional permits will be needed for the installation of a new septic tank. Although the building is plumbed for draining, no facilities currently exist. As a commercial space (and considering the average diet of our average client) we’ll need to make provisions for the extra waste.

On the ground floor we have 190m2 of space to work with, as well as first floor decking that adds roughly another 50m2 of space. The floor is 18.72m by 10.2m of poured concrete without rebar. According to my dad (who built the shed), the concrete has an average depth of 6” and is poured on between 6” and 3 or 4ft of hardcore. (Update: Just after getting off the phone with my dad. He says that there might be a damp course after all... sadly he can't remember.) According to the engineers who laid it, it’s rated at 36N, but I have no idea what this means. :P

As you can see from the pictures, the walls are concrete blocks (9” or 255mm thick) with no cavity insulation. They reach a height of 2.46m, with 600mm clearance between the tops of the walls and the joists for the first floor decking. I-bars are set into the wall at an equal spacing and serve to suppport the corregated iron and plastic roof construction. As far as I’m aware, it’s 1.8m from the bottom of the decking to where the roof starts to taper off into that dome. Height from bottom of decking to apex of the roof is (I think) 3.9m. The trusses have a span of around 10.5m.

The decking is constructed from timber joists built into I-bars spanning between 4-5m from the central support. The edge of the decking comes to almost the exact center of the building. The central support is also aligned to the center of the decking. (Looking at the photograph, it’s approximately 5m to each wall and 5m to the start of the stairs from that central I-bar.) The decking is topped with a sheet of what looks like MDF or something similar. The interior roof above the decking has been sprayed with a waterproofing course to prevent drips from leaks and condensation.

As already stated, the building is plumbed for water at one point near the door, although no facilities currently exist. It is powered from the domestic supply at the house, approximately 50m or more away, feeding into a circuit board near the door. Currently this serves a number of power sockets and the overhead strip lighting.
Goals
A large, spacious live room and control room, as well as two or three isolation booths. TL to the outside is not a problem as our nearest neighbours are half a mile away on the opposite side of the building from where we plan to bulid the live room. Our main goal is to achieve the best possible isolation between the control room and the live room and booths. We also want to install shower and toilet facilities for customers and perhaps have some kind of ‘green room’ or recreation area where they can just hang out.
Restrictions
The I-bars that support the first floor deck cannot be moved. They are load bearing and rated way above domestic requirements. Also, the location of the toilet facilities is limited to the point where the drainage pipe is laid. At the moment, we haven’t quite found it yet, but we know that it’s in the general area of the door. :P (Wish I could be more specific.)
Questions
1. After looking at a number of the awesome build diaries on the site and after talking to an architect, it looks like we’re going to have to put a damp course and insulation down on the floor, followed by another pour of concrete, screed, etc. Is that correct?
2. Considering that the building has been standing for over fifteen years with absolutely no sign of any damp rising through the concrete, could we get away with putting the floor down directly on top of that without the damp course?
3. Is this something that has to be done to comply with Building Control, or is it just a preventative measure (in other words: ‘just in case’)?

One of the young, foolish minds behind this endeavour. ;)
I’m working with a friend on making up a Sketchup representation of the existing structure, as well as the proposed studio design. Apologies for the lack of plans, dimensions, etc. I’ll add these in as soon as possible. For now, I’m mainly worried about the floor itself as I’m in the process of trying to figure out an average ballpark figure for costs.
I'm really looking forward to hearing feedback from you guys and I really hope you can help. I've already learned so much here (and from Rod's book) that I think this is the best place for me right now. :D
All the best,
Padraig.
