2. An ICF Addition
This cottage on the Scottish Borders has been subject to a large extension constructed using insulating concrete formwork (ICF) from Beco Wallform.
- Location: Scottish Borders
- Cost: Approximately £12,000 (for the Wallform structure)
Completed by Border Oak, this oak and glass single room extension has been added to a listed Arts and Crafts house, and joined with a modern frameless glass connection so that the two parts can be easily distinguished.
- Cost: £45,000 (for the supply and erection of the oak frame)
4. A Modern Orangery
The owners of this period home wanted to introduce more space, and commissioned Anglian Home Improvements to add an orangery extension.
- Cost: £18,000 (for design, materials and installation)
5. A Kitchen Diner Extension
With a view to creating a more traditional space in keeping with the existing building, the clients behind this project were keen to knock down the old side extension to make way for a new addition.
The extension, designed by Design Squared, is clad in white render, and houses an open plan kitchen/dining/living area that is connected to the rear reception room.
6. A 1930s Semi Extension
The challenge for Samantha Worrall, an architect by profession, and Philip Osborne was how they could create more space for their growing family within their 1930s semi-detached home on a limited budget.
The answer to the problem came in the form of a crisp and contemporary rendered extension to the rear of the property, along with a small side extension that runs down one side of the house.
- Cost: £40,000
7. A Glazed Lean-To
The owners of this stone-clad home in Frome, Somerset were looking to create additional space off their existing kitchen. The couple opted for a lean-to conservatory filled with natural light.
Enlisting the services of David Salisbury, the design team at the company created a simple but effective design to perfectly fit the bill, complete with two skylights and top-hung windows for ventilation.
- Cost: £40,000
8. A Seamless Addition
After previously carrying out a garage conversion to this 1970s semi-detached home, Eclipse Property Solutions was enlisted once again by the homeowners to build a new kitchen/dining/family space to the rear.
- Cost: £49,000
9. An Oak Frame Kitchen Extension
With a growing family, the owners of this three bedroom detached house in Staffordshire were becoming increasingly constrained by the property’s size.
Reluctant to move out of the area, the homeowners appointed Croft Architecture to come up with a design concept that would see their old, cold, leaking conservatory replaced with a modern, light-filled, open plan extension.
- Cost: £50,000
10. A Semi-Detached Home Extended
When the homeowners bought this semi-detached home in London, they knew immediately they wanted to create a new extension to the rear of the property.
A new 8m x 5m flat roof extension was built and clad in London Stock bricks to match the existing brickwork, with reclaimed bricks, also London Stock, used internally as a feature wall. A bank of rooflights brings natural daylight into the new space.
- Cost: £45,000
