Home Office Shed - insulation & heating.
I am considering building a home office in the garden (kind of elaborate
shed). Size would need to be around 6ft x 10ft. I am thinking of starting with a regular commercial shed, and doing a DIY conversion. Has anyone done this? I need to add the maximum insulation to help keep it warm/reduce heating costs/keep cooler in summer, and add a double glazed window, and extenal door. What is the best way to add insulation, and what thickness is required to meet the highest insulation standards. I want to end up with a white/magnolia flat finish on the walls, and a laminate floor. What would be cheapest way to heat the "office". Some heat will be gained by the computer/lighting etc. Would it be better to use underfloor heating under the laminate, or a aircon unit (as a heat pump), or something else? |

Mmm. You should be able to wedge about 50mm of celotex between the structural bits, and plate over with foil backed plasterboard. Paper or skim or both and paint. Floor is a bot more of an issue. Ether replace it completely with an insulated tupe or put studowrk across it,celotex insulate, chip out and laminate it. What would be cheapest way to heat the "office".

To be honest, the computer/lighting stuff should be enough. Backed up with an electric heater for really cold days. UFH means really designing a custom floor from scratch and unless wet is no saving at all. Aircon isn't bad..but its an expensive install. You have to balance installation costs (a couple of quid for an electric heater versus thousands for aircon or UFH) - against running costs over the units lifetime. A couple of grand buys a lot of electricity. A small shed well insulated should only need 200-500W to be cosy. The lower end of that is about what all the installed gear+ human will generate like as not. That leaves 300W to find. |

So presumably none of this is subject to planning regs, even though you'd effectively end up with a habitable space behind a shed facade. |

I don't know the answer to that..I think it probably IS subject to planning, if they catch you at it, yes. Change of use etc. |

IIRC providing that it's more than a specified distance from a neighbours boundary and below a certain size, then no planning permission or building control is applicable as it's "Deemed To Satisfy" BUT - as it's intended to be wired for electricity, then Part P of the building regs will apply. It's a long time since I delved deeply into planning and building regulation matters, so this info may well be long past its 'sell by' date. Brian G |

There is a point at which it ceases to be a 'temporary structure' and becomes a 'new residential or commercial' structure. IIRC. Not sure at what point that happens..maybe a functional toilet?;-) Brian G |

Brian G I'd be interested if anyone has more detail on this, particularly the distance from the neighbour's boundary. My son is hoping to build himself some kind of bunker/studio down the end of the garden. |

said: I'd be interested if anyone has more detail on this, particularly the distance from the neighbour's boundary. My son is hoping to build himself some kind of bunker/studio down the end of the garden. Yes, I looked at that. If you want to avoid having to deal with the bureaucrats, you have to look at both building regulations and planning legislation. For the purposes of these, you can find enough information on the web site of either your local authority's web site or that of another. I won't reproduce all of the factors here, but you have to look at: - Permitted development rights for the property. Get the original planning consent and see whether any specific limits have been set, or defacto allowances removed. This will tell you whether or not you can use the generic allowances which determine what proportion of the plot can be built upon and the proportions in relation to the main house. - Take a look at the Land Registry records and other documentation for the property (colloquially known as the "deeds") and see whether there are any specific covenants limiting what you can do Assuming that those tests pass and you can use the generic rules, the aspects to look at (again involving planning and building control) a - Volume of the building - Floor area - Distance from any highway - Distance from boundary. This one is supposed to be 1m, but in the context of sheds is widely ignored. - Height of the building. There is a 4m limit here to the apex of the roof. This can be a determinant of floor area as well, although the design of the building can help here. For example, one can have a sloping roof with a low slope or a cabin with low pitch to the roof. Unless he wants to build something massive, it should be possible to stay inside the rules and not involve the jobsworths. |

I understood this did not apply to a building such as a small shed if the floor area was less than 15 square metres - and only applied to a buildings between 15 and 30 square metres if it was not constructed of "substantially incombustible material". Hence the typical wooden garden shed is exempt. James |

The idea is to move to a house where this would be most feasible, so there aren't any specific details as yet. However, I believe it involves a grand piano so I'm staying out of it if I can. |
