Home extensions have become increasing popular with a more stagnant housing market as many home owners chose to improve rather than move. The increase in the number of home extensions being built has also been increased due to the relaxation of planning laws in recent laws. Also home extension designs have improved along with technical advances in materials and building techniques. This has allowed architects, homeowners and building contractors to indulge in more contemporary and stylish home extensions. Also homeowners are looking to active open plan living spaces for entertaining and family living space. The use of glass and incorporating indoor outdoor living has lead to a popular addition to many home extensions of Bi- folding doors. Also many home owners are following the lead of large house builders and property developers by adding French doors and Juliet baloneys to upper floors of their homes and extensions. These are obviously popular when home owners enjoy large gardens or open aspect views. Many are also adding features like under floor heating to avoid taking up space in their new home extension with radiators. Often it is now the case that home extensions are opened up into the main house by inserting an RSJ or steel beam to allow for the removal of large sections of masonry walls. Also ridge beams and other structural designs are being used more commonly to create open ceilings and warm roof design. With these increasingly complex designs using a variety of materials and technologies it is becoming increasingly difficult to rely on a one man bands to tie together all these elements. Many home owners are opting for design and build companies who can provide a one stop solution for the whole building project. This gives the home or building owner not only one point of contact but also more control over costs and extras as design and build companies tend to take extra care when designing and pricing works to avoid extra costs. If you employ an architect and separate main contractor builder there is always a chance of additional costs if there are issues with the design or the contractor has not fully understood some items of the designs or ground works.
