Loft Conversions

Does your home have a loft? If so, have you thought about your use of it? Is it just a storeroom for temporarily or even permanently used ‘junk’? The loft is often our home’s largest area but we rarely give that a thought, so a loft conversion could enhance both our living space and the value of our home! Some lofts are not convertible, although most are.

If you are considering loft conversions in North London, North West London or Hertfordshire, BAPM LTD will advise and discuss the various external styles, depending on roof shape as well as the internal design. Mansard, Dormers, Rooflight/Velux™ options are generally adequate for those contemplating the smaller loft conversion, generally for a single bedroom, study, etc, where adequate height is available within the existing loft space. Rooflights/VeluxTM can be installed with minimum disruption, as the shape of the existing roof does not need to be altered.

Garage Conversions

Not only are we specialists in loft conversions but we can also offer garage conversions. Does your home have a garage? If so, have you thought about your use of it? Is it used for parking your car or just a storeroom for temporarily or even permanently used ‘junk’? BAPM LTD can convert your cold and under-utilised garage into a warm and habitable room and in so doing, adding considerable value to your property. Typical Uses Of A Garage Conversion: A Family Room / A Bedroom / A Playroom / Office or Study / Kitchen / Utility Room / Dining Room.

If you are planning a garage conversion there are many considerations to be made, from design to planning through to construction. We at BAPM LTD are happy to work and liaise with your own designer/architect or you may choose to use one of our own recommended designer/architect’s.
