Loft Conversion Checklist Questions to Ask in Harrow

A good checklist of questions to ask during a loft conversion project will ensure that the whole process goes as smoothly as possible. These tips will help you avoid problems and ensure that the entire project is completed safely and correctly. The following questions are important to ask during a loft conversion:

1. How will you use the loft conversion space? What is the purpose of every rooms and the size? Whether it is a bedroom or an entertainment room or gym or office or playing areas the purpose of the room is essential.

2. What color schemes you want for each? As well as what kind of textures you want for your walls and floors?

3. Want to turn a loft into a large room? Or making few small rooms?  Will the resulting rooms be large enough to fit your ideas?

4. What materials and style for your new room? Rustic room, Modern room, Cool room or warm room

5. Will there be enough space for an additional staircase? Find a stairwell with a good design and the necessary height.

6. What kind of staircase should you use? It is very important about the kind of stairs choose. You can either choose a spiral staircase or a traditional, fixed ladder, but you need to consider the width of the stairs.

7. Where do you want to place the windows? There are also privacy concerns. Do any windows face your neighbors' windows or home and cause privacy issues? A good design will have plenty of windows.

8. Do you want to emphasize natural daylight or interior light? Lighting is another important factor in a loft conversion. The right lighting can make the difference between a warm, comfortable room and a dark, drafty one. A good design will have plenty of windows and lights to provide the most light and balance in your home.

9. Have you consider the type of loft conversion like Dormer, Velux, Hip to Gable, Mansard conversion.

10. Where do you want to place the power sockets and switches?  The electrical wiring is accessible and safe? If it is not, you may want to consider rerouting the wiring.

11. Any specific ideas for fixtures and fittings?

12. Consider the location of the stairs, slope of the roof and the size of the walking area. The slope of the roof determines the size of the walking area and stairs. These factors can affect the size of individual rooms and the overall layout of the loft.

13.  If you install a bathroom that requires water, please check whether there is enough pressure in your existing boiler to carry the hot water to the extra floor?

14. What type of furniture you will use?  You must also consider the type of furniture and other items in the loft.

15. Noise pollution is a huge issue in homes. Turning the loft room into a children’s play area can cause sound disturbances directly downstairs to the bedroom. Make sure your family will be comfortable with the noise levels.

16. How much headroom do you need? You should know how much headroom you need before you start the conversion process.

17. What is the size of the space? You must also consider the dimensions of the space. Are there chimneys and water tanks in the area? The type of roof that you want to convert depends on the type of house you have. You can convert a traditional roof with rafters if you have a flat roof.

18. What is the Size and style of the room? This will determine the style and design of the space. Depending on your preferences, the materials can be different or the same.

19. Whether you are considering converting your loft, or simply want to update your home, you need to get permission from your neighbors if you share a wall with them. The Party Wall Act 1996 makes this process easier than ever and protects your property.

You should also consider the time spent in discussing the plans with your neighbors. This will help you build a better relationship, warn them of your intentions and make sure they are on board with the project.

Here is an example of a Loft Conversion we undertook in Harrow recently. This was a hip to gable and a rear dormer loft conversion. We added a master bedroom for our client finished to the highest standard. We can arrange viewings for you to see our properties that we have worked in Harrow and West London.

Whether you want a DormerGableVelux or Mansard Loft Conversion, we will make sure your Loft is completed perfectly to suit your requirements.

What Things to Consider before undertaking a Loft Conversion?

Head height - Do you have adequate height for a loft in Harrow? 

A potential room in the loft needs a height clearance so that the measurement from the highest point of the roof to the floor should be a minimum of 2.3 meters. To make the space habitable make sure that the loft space in your Harrow house must have the height as stated by the local building regulations.

Strengthening the roof and floor

Consider the structure of the loft conversion. In some instances, you need to provide more strengthening for your loft by using steel beams to underpin the floor and roof itself. This will be required if the structure of your house is deemed weak by the structural engineer. It is for your safety and the durability of the house that roofs and floors are strengthened.

Loft staircase

The Law stipulated that any loft conversion must have its own permanent separate staircase. However, stairs must be provided for a loft conversion to fit the measurement of the area allocated but it does not need to follow the width of the steps on lower flights in the home. Make sure the landing of the loft has enough space for head clearance. 

Use natural light

Loft needs lots of natural light. One option is to install roof/velux windows or skylights so there will be more lights and extra ventilation to the room. Use skylight access for a fully open roof window to provide not only natural light but also a point of access to a roof terrace or other outdoor roof space. This is a cost effective thing to do and it reduces your electricity bill in the long run. 

About planning permission

Not all loft conversions require a planning permission as the rules were relaxed way back October 2008. But to be sure. check before carrying out any serious work. However, if your dormer or Velux windows are in the front of the property then you will need planning permission. Anything that alters the roof will require planning permission.
