Add interest, light and space to your home by building this studio window conversion. Its sloping glazing panels admit plenty of light, and are double glazed to retain heat.
A studio window is one of the best ways to make most use of available light. The sloping glazing panels in this design are upturned to the sun to present the largest possible heat collection area. Using this design, you can construct an attractive rear extension, which will really open up the view into the garden, and create an ideal environment for a conservatory housing indoor plants. Sealed double-glazing panels are used throughout, so there will be no problem with heat loss or insulation efficiency.
The rear entrance is housed in a small lean-to extension with a sloping roof and existing small window. But there are many other ways to use the design. You can just as easily build on to a flat roofed extension, or, directly on to the wall of the house. In each case, all you need do is provide a low retaining wall for the lower part of the window frame, and a secure fixing for the top bearer bar which can be bolted to the wall and covered with a flashing.
Before you begin work, you should plan your window carefully. The first thing to check is that your proposed alteration will not infringe building regulations or local planning restrictions. You should also consider the siting. Ideally, to admit the maximum light, it should face south. If this is not possible, aim to find the brightest location available avoiding obvious shady areas. You should not site it too near trees for this reason, and also because falling leaves will have to be cleaned off the glass in autumn.
The first thing you will need is a foundation for the new structure; set this out then lay a concrete slab to form a floor and provide footings for the retaining walls. How deep this slab must be will depend on local soil conditions; check this point with the building inspector. Build the retaining walls on to this, tying in to the existing brickwork where necessary. The sloping side walls can be extensions of existing walls as shown, or completely new structures tied in to the house. Enlarge the wall opening as required to provide access to the new structure, supporting it with a lintel.
Build up the glazing frames on the brickwork, using the sections shown. If you are building up against a side wall, you can tie in to this as shown.
Fit flashings, bargeboards and soffits, and install sealed double-glazing units, which you can have made to measure. Paint or varnish all the timber for maximum protection, and make sure that you have sealed thoroughly around the edges of the frame to prevent leakages, using a waterproof mastic throughout.
You do not have to build a complete extension to take advantage of this design. All you need is an opening in the walls, supported by a lintel, but you may be required to extend the house foundations under the new structure. Build the low retaining wall around the perimeter and erect the timber supports for the glazing. Just fix the upper bearer to the lintel, and form a flashing to the wall to prevent rain from entering.
