Over 25 Years Experience in Loft Conversions

The Loft Conversion Company (Portsmouth) Ltd can convert your loft into that much needed extra bedroom, office or spare room/guest room.  Converting can be much cheaper than moving or building an extension.  It makes full use of wasted space and will increase the value of your property.  This type of extension has remained fairly popular since we first started designing and constructing them over 25 years ago.  Perhaps even more in demand now than ever before, especially in dense urban areas where the alternative choices for that much needed bedroom are somewhat limited.

A recent survey by mortgage lender Abbey suggested that at least 50% of home owners find the cost of moving unaffordable and decide to stay put.  Converting existing space offers an affordable way to gain that much needed extra room.  Another fact to remember is the cost to carry out the work may be less than the rise in the value of your property after your loft conversion.  A very economic decision according to Abbey.

Remember your loft is a blank canvas.  Giving you the chance to create a room which suits your purpose.  If properly planned and well executed, will provide an attractive addition to your home.  Get the finish right and it will appeal to potential buyers increasing the price and saleability.  Adding an extra bedroom can add an average 35% to the properties market value!

We get many requests to carry out feasibility surveys for loft conversions.  It is supremely paramount to our company to provide the best service from initial feasibility survey to completion.
