<\/span><\/h2>\nThere are several key factors to consider when considering whether to opt for a double-story or single-story extension. Here’s a brief and compact comparison:<\/p>\n
Space:<\/strong> Double-story extensions offer twice the floor area, allowing additional bedrooms, bathrooms, or living spaces on the second floor, making them suitable for growing families or specific needs.<\/p>\nCost:<\/strong> Double-story extensions are generally more expensive than single-storey extensions due to the increased construction, materials, and labour costs of building an additional floor.<\/p>\nPlanning Permission:<\/strong> Double-storey extensions often require planning permission due to their larger scale, while single-story extensions may sometimes fall within permitted development rights.<\/p>\nDisruption:<\/strong> Building a double-story extension can significantly disrupt your daily life as the construction process may take longer and involve more extensive structural changes.<\/p>\nProperty Value:<\/strong> Both types of extensions can increase property value, but double-storey extensions have the potential to add more value due to their larger square footage and enhanced versatility.<\/p>\n<\/span>Types of Double-Story Extension<\/strong><\/span><\/h2>\nWhen considering a double-storey extension, there are different types to choose from based on their relative position to the existing building. Each type offers unique advantages and considerations. Here are the main types of double-storey extensions:<\/p>\n
<\/span>Two-Storey Rear Extension<\/strong><\/span><\/h3>\nA two-storey rear extension is built at the back of the house, often in the garden area. This type of extension is well-suited for detached and semi-detached houses. In some cases, a terraced house extension at the rear may also be feasible.<\/p>\n
<\/span>Two-Storey Side Return Extension<\/strong><\/span><\/h3>\nA two-storey side return extension utilises the narrow space available at the side of a house without encroaching on the garden area. This type of extension is ideal for ground floor extensions and can bring a change of character to the ground floor layout without compromising the backyard space. It is commonly chosen for semi-detached or detached houses.<\/p>\n
<\/span>Two-Storey Wrap Around Extension <\/strong><\/span><\/h3>\nA two-storey wrap-around extension combines a rear house extension and a side extension. It substantially adds to the existing house and offers maximum added space. This type of extension is feasible for both semi-detached and detached houses. The two-storey wrap-around extension provides versatility in layout options and can significantly enhance the overall functionality and size of the property.<\/p>\n
<\/span>Two-Storey Front Extension<\/strong><\/span><\/h3>\nThe two-storey front extension is the least common type of double-storey extension, and extending at the front of the house has the most noticeable impact on the property’s appearance. Due to its visual impact, local councils often apply stricter rules and regulations regarding alterations to the front fa\u00e7ade. However, it can still be viable, particularly for detached houses with a spacious front garden.<\/p>\n
Each type of double-storey extension has its benefits and considerations. By carefully considering the different types, you can decide on the best double-storey extension for your home.<\/p>\n

<\/span>Designing A Double Storey Extension<\/strong><\/span><\/h2>\nWhen planning a double-storey extension, it’s essential to consider the interior layout and prioritise your needs. Hiring professional designers and builders is recommended for a smooth outcome. Here are key considerations for designing your double-storey extension:<\/p>\n
<\/span>Interior Layout of Your Double-Storey Extension<\/strong><\/span><\/h4>\nYour extension’s purpose, whether it’s a kitchen, bedroom, shower room, or playroom, will dictate the design requirements. Pay attention to small details, as they can make a significant difference. Professional guidance ensures optimal design and functionality.<\/p>\n
<\/span>Downstairs<\/strong><\/span><\/h4>\nA double-storey extension allows for improved layout of existing spaces. Consider creating an open-plan living room or a larger dining space for a kitchen extension. Utilise the opportunity to add a utility or laundry room. Optimise the use of space by avoiding unnecessary hallways and corridors. Strategic column placement is crucial for maintaining uninterrupted open-plan areas.<\/p>\n
<\/span>Upstairs<\/strong><\/span><\/h4>\nConsider your goals for the new space on the upper floor. If it’s a bedroom, prioritise features like an ensuite, which adds value to the property. Be mindful of building regulations concerning staircases, landings, and corridors. Seeking professional advice during the layout design phase helps avoid costly issues later.<\/p>\n
<\/span>Roof<\/strong><\/span><\/h4>\nDesigning the roof of your double-storey extension involves the following considerations:<\/p>\n
Planning Requirements:<\/strong> The design of the roof must comply with planning regulations. However, you still have choices within those requirements.<\/p>\nGreen Roof or Flat Roof:<\/strong> If neighbouring properties overlook the extension’s roof, a green roof can be a favourable option for planning approval. If one cannot see the surface from the ground floor, a flat roof can be chosen, ensuring that the visible parts blend harmoniously with the existing building.<\/p>\n<\/span>The Indoor-Outdoor Link<\/strong><\/span><\/h4>\nEnhance the connection between your indoor and outdoor spaces in your double-storey extension:<\/p>\n
<\/span>Bi-folding or Sliding Doors:<\/strong><\/span><\/h4>\nBi-folding or sliding doors leading to the garden create a feasible transition between indoors and outdoors. They provide an opportunity to bring in more daylight and create a sense of immersion in your garden, regardless of the weather. Glazed walls and structural glass are additional options to consider in consultation with an architect.<\/p>\n
By carefully considering the exterior materials, doors and windows, roof design, and indoor-outdoor link in your double-storey extension, you can create a cohesive and visually appealing space that complements your existing property while maximising your connection to the outdoors.<\/p>\n
<\/span>Choosing Buying Material for Your Extension<\/strong><\/span><\/h2>\nWhen choosing exterior materials for your double-storey extension, consider the following:<\/p>\n
<\/span>Matching or Contrasting Materials<\/strong><\/span><\/h4>\nChoosing materials that match the existing building is the easiest option for planning purposes. However, contrasting materials like glazed or naked concrete extensions can create a stunning visual contrast for period properties. Consult with an architect or designer to explore all options and find the best creative design for your property.<\/p>\n
<\/span>Matching or Contrasting Windows<\/strong><\/span><\/h4>\nWindows should either match the existing ones or be chosen in contrast. Bi-folding or sliding doors, glazed walls, roof lights, and structural glass are all options to evaluate with the help of an architect. Select the options that align with your priorities and enhance the overall design.<\/p>\n
<\/span>Having A Double-Storey Extension Is Beneficial<\/strong><\/span><\/h2>\nConsider the following points regarding the potential value added by a double-storey extension:<\/p>\n
<\/span>Cost vs. Value<\/strong><\/span><\/h4>\nIn the short term, the build costs of a double-storey extension may minimise immediate added value in certain locations and properties. However, considering the increased scope and size of the property, the overall cost of the extension may still be more cost-effective than purchasing a larger house and moving.<\/p>\n
<\/span>Prior Renovation<\/strong><\/span><\/h4>\nIf you are planning to sell your old house, undertaking a renovation before selling can increase your asking price. Including a double-storey extension as part of the renovation can be more economical than doing the renovation and extension separately.<\/p>\n
<\/span>Cost-Effectiveness<\/strong><\/span><\/h4>\nDouble-storey extensions are generally the most cost-effective extensions per square meter. For example, in London, they typically cost between \u00a31,800 and \u00a32,800 per square meter, while the property price per square meter in cheaper London boroughs is around \u00a34,000. This cost advantage can contribute to the added value of the property.<\/p>\n
While immediate added value may vary depending on location and property condition, a well-executed double-storey extension can provide a cost-effective way to increase the value of your home and enhance its overall appeal.<\/p>\n
<\/span>Designing A Double Storey Extension<\/strong><\/span><\/h2>\nDesigning a double storey extension goes beyond creating more space. It involves careful consideration of the interior layout to meet your priorities. Some key points are as follows:<\/p>\n
<\/span>Interior Layout of Your Double Storey Extension<\/strong><\/span><\/h3>\nDifferent purposes, such as a kitchen, bedroom, shower room, or playroom, have varying requirements and details that can make a significant difference. Hiring professional designers and builders is wise to ensure a smooth outcome, given the financial investment and potential disruption involved.<\/p>\n
