Over 25 Years Experience in Loft Conversions

The Loft Conversion Company (Portsmouth) Ltd can convert your loft into that much needed extra bedroom, office, spare room or 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 receive numerous requests for feasibility surveys for loft conversions. Providing the best advice during the initial architectural survey is vital to our company. Once we determine that your loft is suitable for conversion, we will offer you a detailed quotation for the work. If you choose to accept, our team will get to work on creating architectural drawings, which we aim to deliver to you within a few weeks. We understand how important it is to get this process right, and we strive to ensure that you are satisfied with our services throughout the project.

What Type of Loft Conversion?

There are four main types of loft conversion when it comes to an architect designing it.

  • Velux Roof Window Conversion  — the most straightforward method is to have a Velux roof window conversion. Velux windows are installed inline with the roof and only protrude 75mm above the roof tiles/slates. This type of conversion is the most economic, however, a larger loft is usually required for this type of design. Another benefit to consider is typically no planning permission is required.
  • Dormer Conversion — will give natural light from a vertical window and will add much more space to your loft conversion. These can be designed by the architect using permitted development rights. Front dormers always require planning permission so the architect will design a small front dormer, usually no more than 2 metres in width. A pitched roof dormer is favourable to a flat roof dormer by the planning department. A much higher roof is required for a pitched roof dormer.
  • Gable Wall Conversion — will extend the width/depth of your roof. A gable wall construction is usually designed to allow for the staircase and space for an en-suite shower/bathroom.
  • Mansard Conversion — this type of roof design is less common and will require the entire roof to be removed before work commences. Only used to blend in with surrounding areas so if no neighbours have it then it will look out of place and maybe refused planning permission.

The Benefits of a Loft Conversion

A loft conversion can bring you many benefits. A popular option if you’re looking to add extra space or value to your home. Here are some of the benefits a new loft conversion can bring:

  1. Increased living space: A loft conversion can provide much-needed extra living space, which can be used as a bedroom, office, or additional living area. This is especially useful for growing families or those who need a dedicated space for work or a hobbies room.
  2. Natural light: Loft conversions are often flooded with natural light, thanks to the installation of Velux windows or dormers. This can create a bright and airy space that feels more spacious and welcoming.
  3. Added value to your property: A loft conversion can add significant value to your property, making it a smart investment. It can also make your home more attractive to potential buyers if you decide to sell in the future.
  4. Improved energy efficiency: Loft conversions are well insulated, helping to reduce energy costs and make your home more environmentally friendly.
  5. Increased privacy: A loft conversion can provide a private space away from the main living areas of the house, which can be especially beneficial for teenagers or guests.
  6. Customisation: A loft conversion can be designed to meet your specific needs and tastes, allowing you to create a space that reflects your personality and lifestyle.
  7. Avoiding the hassle of moving: A loft conversion can provide a cost-effective way to create more living space without the stress and expense of moving house.

A new loft conversion can bring you many benefits, from increased living space and natural light to added value and improved energy efficiency. It is a smart investment that can improve your quality of life and make your home more attractive to potential buyers.
