You needs to check your property deeds for any restrictive covenants. Some developers place a restriction on any building work that will affect the external appearance of the house. If there is such a clause, contact them, as it can often be circumvented for a fee. Your other option is to convert the inside of the garage without changing its external appearance. This is often achieved by keeping a front portion of the garage for storage space and converting the rest. Of course, the suitability of this option depends on your intentions for the garage.
Restrictive clauses in your lease - You need to check your property deeds for any restrictive covenants. Some developers place a restriction on any building work that will affect the external appearance of the house. If there is such a clause, contact them, as it can often be circumvented for a fee. Your other option is to convert the inside of the garage without changing its external appearance. This is often achieved by keeping a front portion of the garage for storage space and converting the rest. Of course, the suitability of this option depends on your intentions for the garage.
Planning permission - You usually only need to apply for planning permission to convert a garage when you intend to extend the actual size of the garage. However, check with your local authority as the precise rules do differ.
Building Regulations - If you plan to convert any part of your house into a room to be used as habitable space, you will need to comply with government building regulations. A building control officer will probably need to check your conversion a number of times during construction. More information can be found on the relevant section of the government's website. Again, rules differ so you need to check with your local council. There are some instances where permission to convert your garage may be denied such as:
You live in a listed building or neighbourhood - It is very likely in this case that the external appearance of the house must be maintained as it is.
Your garage conversion would affect drainage - If you plan on concreting over your garden or anything similar, thus putting extra pressure on the existing drainage in place, you may need to invest in a solution to allay the potential for flooding or blocked drains.
Additional insulation is needed - Some councils will allow you to simply add the extra fill to the existing construction, others demand that you dig up the floor and insulate it as if building from scratch. This will affect your budget, so always check first.
Parking restrictions - In some cities where there is a particular shortage of parking spaces such as London, councils can refuse permission to convert your garage from a place where a car is kept.

Loft Conversion Assessment
The features that will decide the suitability of the roof space for a loft conversion are the available head height, the pitch and the type of structure, as well as any obstacles such as water tanks or chimney stacks. An inspection of the roof space will reveal its structure and physical dimensions.

Head Height
Take a measurement from the bottom of the ridge timber to the top of the ceiling joist; the useable part of the roof should be greater than 2.2m.

If you have appointed an architect or designer, invite them to illustrate clearly how much headroom there will be across the floor in the finished space. Some people are disappointed by how much standing space they actually have, and this isn’t always conveyed on plans.

The Building Regulations impose no minimum ceiling height for habitable rooms. The headroom standard for stairs of 2m applies, but this can be relaxed to 1.9m or 1.8m on the edge of a stair if necessary.

Water Tank
Without the roof space for water tanks and plumbing, the heating and hot water system may have to be replaced with a sealed system. Unvented hot water cylinders make a better choice than replacing the boiler with a combi (combination) boiler but they do take up a cupboard-sized room, which you will have to find space and budget for.

Pitch Angle
The higher the pitch angle, the higher the central head height is likely to be, and if dormers are used or the roof is redesigned, the floor area can be increased.

THE LOFT CONVERSION WILL NEED TO MEET BUILDING REGULATIONS
As a loft conversion is a ‘material change of use’, building regulations must be met. These cover matters of safety, including the strength of the floor, minimum headroom above the staircase, fire escapes, thermal efficiency, electrics, plumbing and glazing. The preparation for building regulations can be completed by either the designer or loft conversion company you are working with.

YOU PROBABLY WON’T NEED PLANNING PERMISSION
Most loft conversions are classed as permitted development, which means planning permission isn’t required, subject to these criteria:

Maximum of 40 cubic metres of additional roof space for terraced houses or 50 cubic metres for detached and semi-detached
No extension is added beyond the plane of the existing roof slope at the front of the house
No extension is higher than the existing roof’s highest part
Materials used are similar in appearance to the existing property
No verandas, balconies or platforms
Side-facing windows are obscure-glazed and open 1.7m above the floor
Roof extensions, apart from hip to gable ones, must be set back at least 20cm from the original eaves
Extensions cannot overhang the wall of the original house
Roof extensions are not PD in flats, listed buildings and designated areas, such as national parks, Areas of Outstanding Natural Beauty or conservation areas
If you do need to apply for planning permission, your architect or design-and-build firm should guide you through the process
