Single Storey Extensions
Adding a single storey extension to the house is one of the common practices embraced by homeowners towards improving the house. Whether you are looking for an expanded kitchen, a big living room, or even a home office, a single storey extension can help in all these ways since it allows for changes in the existing living space thus increasing the worth of the house. In this article, we will discuss single storey extensions extensively and what to expect from the process starting with the planning permission and ending with possible design ideas.
What is a Single Storey Extension?
A single storey extension is the erection of a new enclosure or an enlargement of the existing one, inside the house and with respect to its ground floor. Such construction generally is done at the side or rear yards of the building and is limited to certain sizes, depending on existing requirements and the space available.
It is common for people to construct single storey extensions in order to:
Make the sitting room less cramped.
Make the kitchen or dining area larger.
Provide an additional room or office space.
Construct a laundry room or put a conservatory in place.
For an average single storey extension of 20 square metres, the build cost would be from £30,000 for basic quality build costs
Advantages of a Single Storey Extension
Enhance the Living Space Available: This lets you combine the use of the internal space with the extension outwards thus bringing ease to plan the arrangement that is suitable for the occupants.
Raise the Value of the Property: An attractive extension increases the resale potential of the property which is a great plus for the owner.
Saving Expenses Related to Relocation: Instead of changing residences to accommodate growth, a single storey extension helps by allowing you to increase the space of the existing residence without moving out to a bigger house.
Bespoke: Design the extension in accordance to your needs; be it a stylish cooking area, family space or even a home office.
Planning Permission for Single Storey Extensions
A number of single storey extensions may be classified as permitted development rights thereby eliminating the need to seek formal planning permission if an extension complies with the requisite conditions. on the other hand, you shall seek permission if you desire to build an extension that goes over and above the following policies:
For an extension made to an attached house, the maximum rearward projection of the original house shall not exceed 3 meters while for detached house this shall not exceed 4 meters.
No part of the extension shall be higher than 4 meters.
The extension shall be less than 50% of the original house’s curtilage.
It is advisable to consult the local planning authority or otherwise seek assistance from an architect on the project to avoid going against the law.
Building Regulations for Single Storey Extensions
Even if your extension doesn’t require planning permission an extension will still need to adhere to building within the neighborhood. These protect the end-user as to the quality of energy used and the quality of construction and are usually the most important areas. Some of the key aspects of the building regulation are:
Structural Integrity: This is to make sure there are no structural problems with the foundation, walls, and roof.
Fire Safety: Incorporating fire doors, escape routes and smoke alarms.
Energy efficiency: The use of appropriate insulation, glazing and heating systems.
Electrical and Plumbing Systems: Standards for electrical wiring, outlets and plumbing systems.
At Yoop Architects, we take care of securing building regulation approval from the local authorities, making it simple and easy.
Design Ideas for Single Storey Extensions
Open-Plan Living Area: Design an extension for the kitchen or living room that turns both rooms into a large open plan space ideal for contemporary living. Bi-folding doors or large windows can be added to provide greater accessibility to the outer area.
Modern Kitchen Extension: Enlarge the existing kitchen by adding a cooking and dining space adjoining it. Fit a central kitchen island furnished with modern appliances and skylights for glam as well as natural light.
Conservatory or Sunroom: Install a sunny and bright conservatory with plenty of floor to ceiling windows. This can serve as a dining area, or living space and can also be converted into an office.
Home Office or Studio: As more individuals do their jobs from home, a home office or studio extension can make for a distanced and constructive place.
Family Room: Put up a family room that encompasses a wide range of activities and has sufficient space for leisure, entertainment, and storage. Incorporate built in cabinets, a television unit, or a play section for children.
Single Storey Extension – Key Considerations Before You Proceed
Budget: Put in place practical costing that addresses every single detail of the project from conceptualization, finishing, and construction.
Planning Permission and Regulations: Verify the extension complies with the requirements of planning permission and building regulations prior to the commencement of works.
Design and Layout: Collaborate with an architect and design a layout that fits well with the existing structures of the house as well as the addition.
Future-Proofing: Evaluate how the intended extension will be used in the future. Think of possible space uses that may serve different purposes as time goes by.
Lighting and Ventilation: Enhance natural lighting and air circulation in the room by installing skylights, big windows and/or sliding doors.
