It then takes time to fit the ridge steel, put in the main wall plate, and generally sure that the Dormer is set within the roof and properly finished. No, unless a new chimney or flue extends more than 1 metre above the highest part of the house roof.
I also cut one end of the dormer ridge to match the common rafter pitch and leave the other end long for trimming in place. Also, the shape of the roof is a hip roof style, as we can see by the roof planes facing out resting on all of the walls. If you do rebuild the roof and dormer, the interior walls will need to be present to properly generate the roof and dormer. Your looking back and explaining what went well and what could have gone better is just as helpful as the design and construction parts. This LABC video may also help you to learn the differences between Planning Permission and Building Regulations.
Set aside at least a four-day chunk of time for the basic framing, because once the roof’s open, you’ve got to keep at it until the dormer is weathertight. This design is used where the original roof had little or no headroom and creates sufficient volume for an additional storey. It’s always important to factor in egress when designing dormers because the size of many dormer windows won’t meet code for egress. Two main structures are used for roof construction — namely traditional framed type and truss section type.
CO2 emissions are a major concern in today’s environment and you will need to provide a high level of insulation to your roof as part of your loft conversion. The extension includes the construction of a veranda, balcony (not Juliet balconies) or raised platform (a raised platform is defined as anything more than 300mm above ground level – measured at the highest point). In the majority of cases, the second dormer will be constructed above what is usually the existing kitchen or bathroom.
Justice Henry said no. Applying IceTV Pty Ltd v Nine Network Australia Pty Ltd , he held that the Spicers’ initial work and Skyring’s plans were two separate works, and the Spicers’ feedback was not enough to make them joint authors of those finished plans.

Additions include windows set into the existing roof slope, insulation and strengthening of the floor. The plasterboard ceiling in the upper rooms will delay the spread of fire to the roof space in an unconverted house.
From a design point of view, you may be fine doing the plans, but it sounds as though you could benefit from a bit of guidance on the building regulations, and this is where the architect may be of help. Detailed Floor Plans – show the placement of interior walls and the dimensions for rooms, doors, windows, stairways, etc. That said, should a dormer become large enough to be considered a cross gable, it will hold its own as a major element of the home’s design. Flashing is installed along the seams where the dormer s roof meets the existing materials.
First you will need plans and building regs, This could open a hole new can of worms as you are altering the structure of the roof, its possible you already have steel inplace with you already having dormer window but if not this will be required, the roof will need strengthend doubling up on rafters. In the photo above, you’ll notice that the primary rafters have the bevel of the roof ripped on them. Complete the wall framing by building the side walls as shown in Photos 5 and 6. Take care not to bow the top plate when angle-nailing studs. The construction drawings must show how both gravity and lateral (wind and earthquake) loads will be resisted.
This is very similar to the Gable Dormer, but instead of a perfectly flat front, the roof is hipped (the terminology is the same as that used to refer to Hip to Gable loft conversions ). This means that 3 sides of the roof are covered in roofing material, rather than just two on the Gabled Dormer. Once your building permit is issued, erosion control measures must be installed, prior to beginning any further ground disturbing activities. The architect will help you consider issues such as roof slope, interior headroom, exterior appearance, structural strength, roof condition and cost. They can either meet the main ridge or intersect with the existing roof below the ridge.
However, you may not significantly change the character of the building or the area without a building permit. Check with your local planning department to see whether your neighborhood has any building restrictions on dormers, to obtain a building permit for your project and to arrange for any required inspections. Make sure the new rafters line up with the edge of the roof sheathing (Figure A).
We undertake all aspects of your dormer extension through building, joinery, plumbing, electrical, roofing, tiling and decoration as a seamless total build project. Cutting the rafters to install a dormer breakes this triangle and care is required to ensure the overall strength and stability of the roof isn’t compromised. The building, enclosure, pool or container would be situated within the grounds of a listed building.
You’ll need adequate drainage outlets for your dormer in virtually all cases, and these may impact the current drainage systems you have on your roof, so you want to take all of this into consideration when planning your build. The solution needs to be tailored to your house, for example depending on the size of the dormer or existance of other dormers it might be necessary to add a steel beam under the ridge. Using dimensions from your plan, draw lines on the floor to indicate the location of the front dormer wall.
Unless your roof has a breathable felt you will need to leave a void above the insulation and ensure that you have effective roof ventilation to prevent the build-up of condensation. If your loft is below minimum then you may be able to raise the height of the roof or lower the ceilings of the rooms beneath. Clearly it’ll add weight to your house and, although it may only be a modest increase, you’ll need to make sure that the structure of the building can take it. You’ll need to expose the foundations and check them, together with any beams or lintels that will be asked to carry more weight.
In some people’s eyes a flat roofed dormer might not provide the aesthetic appeal of other forms of loft conversion, but does provide the greatest gain in both floor space and headroom. Rather than pre-cutting studs beforehand, I frame sidewalls after the new dormer rafters are set. Use the Roof Style Type drop down menu to select the a Gable, Shed, Gambrel, Mansard, Barrel, Curved Eave, Hip Curved Eave or Eyebrow roof over the dormer.
