Measure the head height

Measure the head height

Do you know that your loft should have a minimum head height of 2.3m for conversion? Yes, there is some limitation on the conversion of loft according to height. There are other impediments which can affect this decision of planning permission such as pitch of the roof, water tanks in loft and chimneys. The loft area has to be less than 2.3m for different options such as removal of section of roof or all of it for increasing the headspace. So, this can add to the cost and will need a planning permission.

Consider the floor below

Consider the floor below

Another plan is to lower the ceiling of rooms below so that the headspace of your loft increases for meeting required height of 2.3m. Again, this process seems to be pricey though you can sort out the problem for more additional space.

Look for other conversions on your street

How can you find the right design for your loft conversion?

Before starting with loft conversion work, it is necessary to consider the layout you require such as – the bathroom, storage areas and where to keep bed. When planning for an ensuite, you must consider the height and internal spaces so that you can place hand basin and shower which should not settle for the headspace. Another factor is the location of stairs. You need to consider all the possibilities so that you enjoy maximum space for your loft conversion. A small decision like where to place the doors can actually create a big difference between boxy loft conversion and the one that remains more open.

Here are two options for designing your loft:

The first option is to hire an architect which can be someone in your area for visiting the house. He will make drawings so that we can turn your dreams into reality. You can tell the architect exactly about the type of design you want and necessary specifications you require internally.

The second option is to give loft specialists in London your entire project so that we can design and build your loft conversion. Our local architects will visit your house and draw designs for you. There is the additional benefit of decreased architect costs and all-inclusive services offered.

Lighting and loft conversions in London

Rooflights or Skylights

Rooflights or Skylights

The most suitable method is to use rooflights or skylights which follow pitch line of roof. This can be fitted with the removal of battens and tiles where the skylight needs to be fitted. The skylight frame gets fitted and surrounding is tiled to the perfect finish. This kind of windows is cost-effective and there is no need for any permission at the time of installing it. You should take out sufficient time and think how you want to install windows in your Loft conversion. Consider the size and where you want to place them as this is very important to determine the amount of light you can get into your loft. Window glazing should make up nearly 20% of loft area if you want natural light to enter into your house.

Dormer Windows

Dormer Windows

Dormer windows add the needed space to your loft conversion other than providing natural light. These are extremely effective when the pitch angle is high as the internal floor area may be increased. The mansard conversion gives the most converted roof space as it projects maximum head space available for bigger and usable internal floor space. The hip to gable conversion also has the same effect.

Do you know the windows position can decide about roof shape to choose?

Having a shallow and long room will be beneficial for windows that have equal space with length. On the other hand, a narrow and deeper room may benefit for one big window. Since all rooms differ in shape and size, you should take time to consider the type of window which will be suitable for your loft conversion. According to loft conversions specialist in London, take time in choosing the right windows so that you can place them properly.

How can a loft conversion make different additions to your house?

Most London properties are small and they do not have extra bedroom or bathroom required for a growing family. A loft conversion is a great way to help with different additions to your home. Most loft conversions in London can help with adding extra bedrooms though there are other ideas for a loft conversion, such as an office, a playroom for kids or a cinema room.

If your property has brilliant views, then make sure you benefit with the addition of a loft room. Many people believe beams and ceilings seem to be a restricted factor for creating a bathroom in the loft. It is quite possible to have bathrooms with easy and convenient access from your bedroom. Another great alternative is wet room or stylish shower but you should check if you have permitted headspace for shower. It is important to have proper-sized windows when there is no requirement for an extractor. This will help to select the perfect shower enclosure for loft space.

Can Converting loft improve energy efficiency of my house

Can Converting loft improve energy efficiency of my house?

The answer is yes and addition of loft conversion will give suitable chance to make your house energy efficient. This is because the installation of insulation is a standard requirement. According to building regulations, there are two kinds of insulation which the local authority or a local building inspector can determine on visiting your house.  They are the cold roof insulation and the warm-roof insulation. The cold roof insulation is made by filling spaces between the rafters with foam insulation, the leftover slab insulation should be attached with the inside of rafters. There should be 5 cm gap between the roof felt and insulation for better ventilation and this makes it the most popular method to use. On the other hand, the warm-roof insulation entails foam insulation to fit over the rafters before the addition of capping, tiles and tile battens.

When making a dormer, this can be very difficult option to use while the roof cover has been taken off.  The foam insulation is 10cm thick slab which insulates a dormer wall while 10cm thick cover insulation is required between plasterboard. This is generally attached to both sides of internal partition wall. Besides, you need 10cm thick insulation between the loft floor joists. So, the insulation work in your loft can reduce energy costs of your house. This helps to know how to insulate your roofs properly.
