About LoftFlat

Living in a loft or a small city apartment is a series of practical questions with real numbers behind them. How many square feet is this room actually? Can I afford the rent on it without the rest of my budget falling apart? How much paint does a wall that tall need? How many lumens will make an open-plan space feel bright rather than gloomy? Is this flat good value per square foot compared with the one across town? And how much air is a heater or an air conditioner actually being asked to move once the ceiling soars? LoftFlat is built around exactly those questions.

Rather than long articles you have to read to the end, the site is a set of small, single-purpose calculators, each aimed at one decision. The Square Footage Calculator totals the floor area of one room or a whole open-plan floor from length and width, in square feet and square metres. The Rent Affordability Calculator turns your gross income into a comfortable rent ceiling using the long-standing 30% rule, with a more conservative 28% figure alongside it. The Paint Calculator estimates litres and gallons from a room’s perimeter and ceiling height, minus an allowance for doors and windows and multiplied by the coats you’re applying — which is where tall loft walls really change the answer. The Lighting Calculator uses the lumen method — target illuminance times floor area — to size the light a room needs and how many fixtures that takes. The Cost Per Square Foot Calculator divides price by area so two spaces can be compared on the same footing regardless of headline price. And the Ceiling Volume Calculator multiplies floor area by ceiling height to give the room volume that heating, cooling, and ventilation sizing depend on.

The numbers behind the tools are ordinary, published ones: area is length times width; the 30% and 28% rules are common budgeting guidelines; paint is sized at roughly ten square metres per litre per coat; lighting follows widely used lux targets for each room type; and volume is simply area times height. Every calculation runs in your browser from the figures you type in — nothing is stored or sent anywhere.

Beyond the calculators, the blog and learn section cover loft conversions, open-plan design, small-space living, and the reasoning behind the numbers the tools produce. The museum is a browsable, illustrated collection with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons, there for the pleasure of looking and learning.

A few things worth stating plainly. LoftFlat is an independent site, not affiliated with any estate agent, developer, architecture practice, or building authority, and it is not a property-listing service. It is supported by advertising, which is how the tools stay free with no account required. Every result the tools produce is a general estimate built on the figures you enter and on common conventions, not a professional real-estate, architecture, or financial determination. For anything that carries real cost or risk — a purchase, a tenancy, a mortgage, or building work — verify with a qualified professional before you rely on a number from this site. If a tool looks wrong, or you think a calculator is missing that would help, the contact page is the place to say so.
