What Can Be Added When Extending Your Home?

A cellar conversion (or basement extension) is one of the smartest ways to add valuable floor area without changing the external footprint of your home. This is ideal if you want extra space for a home cinema, gym, office, utility room or even an additional bedroom.

Basement projects often require detailed design work and compliance with building regulations, including structural considerations, ventilation, damp protection and safe access. MyHomePlans can prepare the drawings needed to support your project from early design through to building control submission.

Best for: adding hidden space, increasing property value, creating premium living areas.

Adding Velux windows (also known as rooflights) is one of the most cost-effective ways to upgrade a loft space or attic room. Rooflights bring in natural daylight, improve ventilation, and can make a previously dark roof area feel bright, modern and spacious.

Velux windows are commonly used for loft conversions, and in many cases can be suitable under permitted development, depending on the property type and location. MyHomePlans can design your layout and produce planning drawings where required.

Best for: brightening lofts, improving natural light, modernising roof spaces.

A gable end extension is a fantastic option for properties with a pitched roof, particularly where homeowners want to increase internal space on upper floors. By extending or altering the gable end, you can create additional headroom and a more usable layout, especially in loft conversion designs.

This type of extension can significantly improve bedroom sizes, allow for better stair positioning, and help create full-height rooms where space was previously restricted.

Best for: maximising loft space, improving upper-floor layouts, creating full-height rooms.

A dormer extension is one of the most popular ways to extend your home upwards. Dormers increase head height and usable floor space, allowing you to create a larger bedroom, ensuite bathroom, home office or even a full additional storey feel within the roof.

Dormer loft conversions typically require accurate drawings for planning permission (if applicable) and building regulations approval. MyHomePlans provides complete drawing packages to support the design, approval and construction stages.

Best for: adding bedrooms and bathrooms, creating major loft space, improving property value.
