On a new dwelling it will maximise use of the built volume and bring down Uthe average cost per square metre. In an existing home, converting the loft is often the most cost-effective way to add space. There are two main options when it comes to design: to commission an architectural designer to produce drawings which can then be put out to builders on a competitive tender basis, or to hand the whole project over to a design and build contractor offering a one-stop service. Both will deal with planning permission, if required, and Building Regulations approval. Think 1 Ahead Designing a roof with future conversion in mind will allow for the expansion of living space should demand arise. Specifying either a cut roof or attic trusses instead of ‘fink’ trusses will add £1,500-2,000 to the average build cost but hugely simplify the conversion process.

    Shedking's Gable Shed Building Guide by John Shank, owner of shedking, LLC 2016 This shed building guide should be used in conjunction with the gable shed plans available at my website shedking.net . These sheds can be used to build storage sheds, chicken coops, playhouses, tiny houses, garden sheds and much more! I have tried to make this guide as simple as possible, and I have tried to make my building plans as comprehensive and easy as possible to follow and understand. If at any time anything presented in the plans or building guide is not clear to you please contact me at [email protected]. As I always advise, please get a building permit and have your plans inspected and gone over by your local building inspector. Many counties in the United States do not require a permit for structures under a certain square footage, but it is still very wise to get the advise of your local building department no matter what the size of the structure. Email: [email protected] 1 Copyright 2016shedking.net If after purchasing a set of my plans and you want to know if they are good for your county, I won't be able to answer that question! All my plans are written utilizing standard building practices, but I cannot write my plans so that they satisfy every local building code.

The amendments seek to protect the vitally important Manhattan based industries from the effects of unbridled conversion of loft buildings to residential use. Concurrently, additional opportunities are provided for housing in areas where residential use will not have an adverse impact on the City's economy. The zoning map changes define current manufacturing districts, create new mixed use districts, and remap a manufacturing district to commercial. The text changes establish standards for the conversion of non-residential buildings to residential use outside the manufacturing districts. The text changes also provide a mechanism for relocation assistance for industrial uses displaced by conversion when they relocate in New York City. BACKGROUND In adopting the 1961 zoning ordinance, the Board of Estimate-- sought to ensure "that sufficient space will be available for use for manufacturing and related activities". Large areas of Manhattan which were occupied by industrial uses were mapped manufacturing. Other areas with significant industrial activity were mapped commercial, because they were adjacent to the central business districts or residential areas. The industrial uses in these commercial areas were expected to decrease over time. The first major review of this policy was undertaken in 1963. In response to the proposed Lower Manhattan Expressway, and to the sug- gestion that the area between Broome and Houston Streets be cleared for high-rise housing, Chester Rapkin was commissioned to study the S.

It is not possible, nor is it intended that this booklet should cover every aspect of the design. Primarily, it's purpose is to highlight the basic design considerations which need to be addressed. Specific technical detail has largely been omitted due to the criteria being subject to frequent change. If the proposal involves the conversion of a loft space above a bungalow, the fire safety provisions indicated in section 4:00 are not applicable, other than the arrangement of inner rooms. 1:20 For the purposes of this guidance, it is assumed the proposed conversion will not: (a) exceed 50 m2 in floor area, (b) involve raising the roof line above the existing ridge level, and (c) contain more that two habitable rooms, on the new second storey.

  • Steps to Planning and Costing a Loft Conversion Uncovering Your Loft’S True Potential Can Be Tricky – Especially If All It Has Been So Far Is Rarely Visited Storage
    LOFT CONVERSIONS Look at what you’ve got To ensure your space is worth converting, and to make it viable as a functioning and practical room, you ideally need the highest point to be at least 2.2m. There should be enough space to fit a new staircase – preferably within the existing landing area on the first floor – and a new landing into the loft rooom. Next, look at the roof. The gradient of its slope should be analysed, explains Sarah Livesey, director at Econoloft, as this will not only dictate the type of conversion possible, but also the finished layout. Generally speaking, the higher the pitch the taller the ceiling, and the more floor space you’ll have to work with. Anything above 30 degrees is workable. If you don’t have much head height, it’s still possible to convert – either by lowering the floor, raising the roof, or altering the shape of it by extending – but the project will cost more. To gain space, think about relocating a water tank if this is housed in the loft. Though 1you may need to install a new boiler or water system anyway if your existing plumbing can’t cope with serving additional rooms. If the loft has a chimneybreast, you may prefer to have it demolished if it will obstruct the layout. “Remember – this will impact the structural stability of the whole property, so it needs to be carefully managed with input from a structural engineer,” says Sarah. “Externally, check the condition of your roof tiles. If you need to re-tile or make repairs, do it as part of the conversion process.” 10STEPS TO PLANNING AND COSTING A LOFT CONVERSION Uncovering your loft’s true potential can be tricky – especially if all it has been so far is rarely visited storage.

But, The intersecting roof consists of a gable and valley, before discussing roof framing, we will first review or hip and valley. The valley is formed where the two some basic terms and definitions used in roof different sections of the roof meet, generally at a 90° construction; we will then discuss the framing square angle. This type of roof is more complicated than the and learn how it’s used to solve some basic construction problems. Next, we’ll examine various types of roofs and rafters, and techniques for laying out, cutting, and erecting rafters. We conclude the chapter with a discussion of the types and parts of roof trusses. TERMINOLOGY LEARNING OBJECTIVE: Upon completing this section, you should be able to identify the types of roofs and define common roof framing terms. The primary object of a roof in any climate is protection from the elements. Roof slope and rigidness are for shedding water and bearing any extra additional weight. Roofs must also be strong enough to withstand high winds. In this section, we’ll cover the most common types of roofs and basic framing terms. TYPES OF ROOFS The most commonly used types of pitched roof construction are the gable, the hip, the intersecting, and the shed (or lean-to). An example of each is shown in figure 2-1. Gable A gable roof has a ridge at the center and slopes in two directions. It is the form most commonly used by the Navy.
