Some of the key aspects you need to consider when planning your loft conversion are: 

How do you want to use the space? Do you need a bedroom, a home office, a playroom, or something else? 
Where will the stairs be located? How will they affect the layout and flow of your existing rooms? 
Where will the windows and doors be positioned? How will they affect the natural light and ventilation of your loft? 
What size and features do you want for your en-suite? Do you need a shower, a bath, or both? 
Other factors to remember are the rules and regulations around loft conversions, and especially their associated fees, which may include: 
Planning permission — Not every loft conversion will require planning permission, but there are instances where obtaining it is compulsory Local council costs for householder planning are £258* (* excludes design fees). 
If you are able to use the ‘permitted development route’, obtaining a Lawful Development Certificate (LDC) is advisable. Whilst not essential, it does establish that the loft conversion is within its legal borders. They cost £129* (* excludes design fees), though this being half the cost of the relevant planning permission and will avoid issues on future sales. 
Structural engineer — Depending on the level of structural alterations to your loft, you should expect to pay from £475 for structural design fees, site visits and calculations these costs are in addition to Architecture Fees. 
Party walls — If you share an adjoining wall with a neighbour, ( Semi detached Properties then you will most certainly need a Party Wall Agreement. This is a requirement of the Party Wall Act 1996. Costs can vary depending on the professional advisers engaged, but there are Party Wall specialists who offer the complete service for fees of around £1,250.
