Landkey Close, Manchester, M23 0FW. Are Mansard Loft Conversions Popular in Manchester?
No, absolutely NOT, Mansard loft conversions are not popular in Manchester and never have been, whilst some loft companys in Manchester state “Mansard conversions throughout Manchester, and you have probably seen many Mansard loft conversions and not realized what they are” We haven’t and are still looking? If you are considering a Mansard! we would advise you to ask to view one. With being involved in loft conversions in Manchester and throughout the North West for over two decades we have never been asked to build a Mansard loft conversion, or have seen one come to think of it.
Mansard conversions were popular in London in the early 90’s, however, in recent years’ planners in London have refused permission for front Mansards, this is to avoid the gap-toothed terrace roof lines. Now, space-starved residents in London are coming together to seek joint planning permission so they do not look out of character (as below) Mansard dormers were/are set back and the face of a Mansard dormer was built on an angle of 72° rather than a standard dormer conversion built at 90° the reason why Mansards were or are built being sloped is that there visually softer and not as intrusive on the street scene than the standard square dormer.
After the great fire of London in 1666 all house had to be built in brick or stone and no wooden eves were allowed, roofs were pushed back behind brick parapets, party (dividing) walls had to be built and thick enough to withstand a minimum fire resistance of two hours, with having two hours of resistance to fire this would give adjoining neighbours the chance to escape and for the authority’s time to extinguish a fire before it could spread, from this time no properties were allowed a Thatched roof, roofs were to be only made from tile or brick (fire resistant)
As you can see from the pic, terraced house parapet walls in London, if not already, have to be built up either side to divide the Mansard conversion from fire spreading to the adjoining property.
Naseby Road, Reddish, SK5 6EH. Can I put a bath in my loft conversion?
Sure, the fitting a bath or a shower in your loft conversion will make a more practical and will add more value to your home, you have to take into account the finished headroom of the loft conversion mainly for the shower screen (rear dormer popular for this reason) introducing a bath with mixer taps is a great asset.
The presence of existing flooring does not ensure that you have a joist system that is substantial enough to support a floor and to have passed with building control, you would have to expose the floor joists, take the dimensions of the beams and the span there are spanning, send dimensions to a structural engineer to calculate the integrity of the joists.
Norris Road, Sale, Manchester, M33 2RF. How much weight can I put in my attic?
The joists/chords are what support the weight, an uninhabitable attic will not have been designed for heavy storage, for storage only it should be able to handle around 10 pounds per square foot live load.
You can, but what is the point, if you are going to the trouble to convert the attic area, the most important issue is it structurally integrity and safety, if it does not have a building regulations completion certificate, selling your home with an unauthorised loft conversion will prove a serious issue for someone buying your home at a later date, you even may be required have to put it back to the original state prior to creating a room, so for the difference to do it right the first time, out ways trying to do it cheaply.
Emery Avenue, Manchester, M21 7LF. Can I build a dormer myself?
You can, as long as it is built according to building regulations, the bad news is, it’s defiantly not a DIYer job when Rafter Loft Conversions are contracted to build a dormer (rear, hip to gable or a wrap-around) we guarantee that it is not only built in one day but also watertight if it is considerably a large dormer a couple of teams would be allocated to have the structure built and sealed in a day.
The bottom chord dead load of a truss varies with the weight of materials attached such as plasterboard on the ceiling, a typical load is 5 to 10 pounds per square foot.
Truss rafters are designed to carry two types of loads which are live loads and dead loads, a live load is a temporary load that creates stress throughout the structure, whilst the dead load is the wind, etc, a dead load is carried constantly by the truss and includes the weight of the structure, i.e. roofing materials, interior materials such as drywall and insulation.

Marquess Way, Middleton, Manchester, M24 4JR. How do macerators work and which are best?
A macerator has a rotating blade that shreds and grinds solids, i.e. human waste and toilet paper, when mixed with flushing water, the solids changes to a fine slurry which moves easily through a narrow pipe which can travel vertical and horizontal to dispose of the waste, Rafter Loft Conversions will only use macerators as the last resort if unable to connect waste the conventional way. The most popular macerator on the market is Saniflow.
When it comes to inserting roof lights or skylights into your home, be it Velux, Keylite or Fakro generally there is not a requirement to apply for planning permission, this is as long as any windows installed must not protrude any more than 150mm above the existing roof plane. (slope)
Knutsford Road, Latchford, Warrington, WA4 1DU. Can the existing attic joists support the floor for a loft conversion?

A good rule of thumb for a floor is half the span, i.e. 2.4m coverts to 8 foot, half of 8 is four + 1 are likely what you require. You must get a structural engineer report to calculate all beams.
Crawford Ave, Worsley, M28 2RE. What height do you need for a loft conversion?

The main two loft conversions Velux & rear dormer can vary considerably, Velux loft conversions start at £18,000 and rear dormer conversions start at £27,000, this question is like asking how long is a piece of string as so many factors need to be taken into consideration, i.e. if you would like an additional bathroom.
Denonshire Road, Eccles, M30 0WX. Which are the best skylights for a loft conversion?
Although there are several brands on the market to choose, Velux® remains our favorite and is no doubt the world’s leading manufacturer of roof windows. Velux offers many sizes in roof windows from 470mm x 980mm to a 3 in 1 window 1837mm x 1178mm.
Manchester Road, Walkden, M28 3NS. Can I build a dormer without planning permission?
If you live in a terraced house your loft conversion must be less than 40 cubic metres, for semi-detached or detached properties no more than 50 cubic metres. Your loft conversion cannot be higher than the highest part of the existing roof profile. The vertical face of the dormer must be at least 20cm from the eaves of the existing roof (internal wall plate) The materials used in your roof extension should match, as much as possible. UPVC will not be acceptable, other than possibly for windows. Loft conversions should be finished in hanging tiles, render or brickwork to match your house and not UPVC, other than windows. If a window is going to be in the check of the dormer, windows within 10.5m of a boundary to the side elevation of a roof slope will need to be obscure-glazed to protect the privacy of your neighbours. A Juliet balcony can be installed but with no platform, any other form of a balcony, roof terrace or veranda requires planning permission. Roof extensions are not permitted in conservation areas, national parks, areas of outstanding natural beauty or a World Heritage Sites, therefore planning permission must be applied for. If your home is a listed building you should consult with your local planning authority to apply for approval.
Ramsey Street, Manchester, M40 5HW. Can we have any references before we commit to having a loft conversion?

Bishop Road, Salford, M6 8PX. Do I need an emergency exit roof window for fire regulations?
Fire escape windows from the loft room are no longer a requirement for loft conversions when two storey properties are transformed into a three storey, provisions for a fire escape are required throughout the full extent of the escape route, including interlinked mains powered with battery back-up smoke alarms in all habitable rooms and each landing, alternatively, a sprinkler system may be introduced, however, a sprinkler system can be quite costly. Different regulations apply to bungalows, bungalows can have a fire escape window and will still conform to Building Regulations.
Avondale Road, Whitefield, Manchester, M45 7JR. We have been told that we will have to apply for planning permission to have a dormer window at the front of our house, but not if it is built at the back of the house, is this correct?
Yes, the rear dormer would be built under your permitted development rights (limits apply) as a new regulation came into force on 30th September 2013 which work can be undertaken without having to apply for planning permission, therefore the statement is correct if your property is facing a highway (public right of way, road or public footpath) you would be required to apply to the local planning authority (this may be refused if no other property in the vicinity has similar) yet, under permitted development rights a mistake in the drafting of the legislation was made and specifies limits for side and rear extensions, the intention was to rule out front extensions altogether, however, the wording in the legislation rules out front extensions where the front elevation fronts a public highway, the government did not take into account the scenario when the front of a property does not front a highway, as in the diagram.

A boundary wall is a wall constructed on land generally, the wall to separate two parcels of land, a boundary wall will normally run through the centre line of the said wall.

Kingsway, Bredbury, SK6 2NS. Can you sleep in a loft room?

Main Road, Galgate, LA2 0LA. Can a wooden floor be fitted in a loft conversion or will it be too noisy?

Leedale Street, Manchester, M12 5SH. Where can you put stairs in a loft conversion?
We cannot say until we have undertaken a viewing on your property, they are many numerous factors to take into account with a new staircase. Building Regulations stipulate minimum headroom not only on the new staircase but also if they are going to be positioned above your existing staircase we need to make sure we have 2m headroom clearance walking down the existing stairs. A good explanation of staircases can be found HERE.
Rafter Loft Conversion can easily reposition any plumbing pipes or tanks to maximise usable space in the loft. We would suggest rather than spend a few hundred pounds to have a water tank moved, nowadays its worth considering a combi boiler which are now really efficient, and depending on how lower the tanks may have to be moved you may also lose pressure due to it being gravity fed.

Rishton Lane, Bolton, BL3 2EN. What is a Velux loft conversion?
Velux® and Rooflight loft conversions are the same, this particular loft conversion is called a Velux conversion due to the popular roof window manufacturer Velux. A Velux loft conversion is when your loft conversion is within your existing roof space and without altering the profile of your roof. Velux conversions are the cheapest option and work’s well when you have good existing headroom to maximise the space available. Velux loft conversions require considerably less construction work and the installation of Velux® windows is a fantastic way of making your loft space feel spacious by allowing natural light and air.
Of course, the simplest and most cost-effective loft conversion for a semi-detached house is a Velux conversion as long it’s a gable end, if you have a hipped roof (where the roof slope’s to the chimney) you would no doubt need a Hip-End dormer, a rear dormer can be introduced at the same time, Wrap-Around dormer. HERE are the different loft conversions.
Park Road, Romiley, Stockport, SK6 4PG. What regulations are involved in a loft conversion?
We have to take in numerous factors for a loft conversion it involves the structural integrity of the new floor and ceiling, structural stability of the existing roof and changes made to party walls, the suitability of any proposed changes to the exterior of the house, in the context of the local area and any special factors relating to the property, safety in the event of fire regarding the escape route, appropriate stairway access, soundproofing between the proposed space and adjoining areas, such as rooms below or through party walls etc.
The actual construction of a typical conversion takes between 3 weeks for Velux conversions and 4 weeks for a dormer conversion, allow an extra few days if a bathroom is going to be installed. If planning permission is required for the loft conversion you should allow a further 8 weeks for it to go through a planning meeting, however, generally, loft conversion comes under your permitted development rights.
