On average, a kitchen fitting takes between 1 to 3 weeks, depending on the complexity of the project. A straightforward like-for-like replacement may only take a few days, while full renovations involving layout changes, rewiring, plumbing, or structural work will take longer. We provide a clear schedule of works before starting, so you know exactly what to expect and when.

Start with a free consultation. We’ll visit your property, assess the space, listen to your ideas, and offer expert advice tailored to your goals. From there, we’ll provide a detailed quote and outline the steps needed to turn your loft into something amazing, whether a quiet work spot or a functional master bedroom.

Yes, all of our work is backed by a workmanship guarantee, ensuring quality and durability. We also ensure that all work meets current building regulations.

In most cases, you won’t need to move out. We’ll communicate clearly throughout the project and do everything we can to ensure you remain comfortable in your home.

In most cases, yes, you’ll need input from both. An architect helps design a layout that maximises space, light, and usability, ensuring the new room blends seamlessly with the rest of your home. A structural engineer is essential for calculating load-bearing requirements and ensuring that any structural changes, like steel beams or altered rooflines, meet safety standards. At Kingdom, we handle this for you by working with trusted professionals to ensure every detail is designed and built to spec, safely and in compliance with Building Regulations.

Costs typically range from £25,000 to £65,000, depending on the type of conversion, finishes, and any structural changes required. We offer detailed, transparent quotes and will walk you through all options to match your budget and vision—without any hidden extras.

So a 20m² extension might cost £36k–£70k+. This excludes design fees, and possible planning costs. A clear, itemised quote from your builder is essential.

Our team at Kingdom Design & Build offers transparent quotes and can help optimise your budget without compromising on quality.

Absolutely. Loft conversions are one of the best ways to increase your home’s value. A well-executed conversion can add up to 20% to your property’s market price, especially if it creates an additional bedroom and bathroom. It’s a strong investment that combines practical space with long-term financial return.

In most cases, no. Many loft conversions fall under what's called permitted development rights, meaning you won’t need formal planning permission as long as your project meets certain conditions. However, there are exceptions, especially in conservation areas or if you're making significant alterations to the roofline. We’d be happy to assess your home and advise exactly what’s needed to keep things compliant and on track.

The average loft conversion takes between 4 to 8 weeks, depending on the size, type, and any structural work involved. We provide a clear project timeline before we begin, and our experienced team works efficiently to deliver on time, without compromising quality.

If resale value is a priority, speak with a local estate agent before building. They can help you understand the potential uplift in your property’s value if you increase its size. In most cases, adding a bedroom or creating a larger kitchen-diner makes a home more appealing to buyers. Orangeries are also a strong investment—they combine extra space, natural light, and beautiful design, making your home more desirable.

Yes, but additional extensions may require full planning permission depending on past works. Our planning team can check your home’s extension history and advise on your options—ensuring everything stays compliant from the start.

Yes, all of our work is backed by a workmanship guarantee, ensuring quality and durability. We also ensure that all work meets current building regulations.

It depends on your location, the type of extension, and current market trends. As a rough guide:

A single-storey extension can add 5–8%

A double-storey extension may boost value by up to 12%

Adding a bedroom or a larger kitchen-diner often brings the biggest returns.

Orangeries, open-plan layouts, and well-integrated spaces are especially attractive to buyers. To get an accurate picture, speak with a local estate agent before building—they’ll estimate the potential new value based on comparable properties. Kingdom Design & Build can then help you design with that value in mind, so every square metre works harder for your investment.

Not necessarily. Many families live at home throughout, especially for rear or side extensions. But expect dust, noise, and limited access to key areas like the kitchen. For major renovations or if your water/electricity is shut off for long periods, temporary accommodation might be wise.

Most single-storey extensions take around 4–8 weeks once construction begins (depending on the size). Add design, planning, and approval stages, and you're looking at 4–6 months from idea to completion. Double-storey builds take longer. The more complex the project, the longer the timeline, so factor in time for decisions, weather, and unexpected delays.

Yes. Good design and structural safety are essential. Whether you're planning a creative open-plan layout or removing load-bearing walls, Kingdom Design & Build provides in-house architects and structural engineers to ensure your plans are both beautiful and compliant.

Costs vary widely. On average:

£1,800–£2,500 per m² for standard finishes

£2,500–£3,500 per m² for high-end or complex builds

So a 20m² extension might cost £36k–£70k+. This excludes design fees, VAT, and possible planning costs. A clear, itemised quote from your builder is essential.

Our team at Kingdom Design & Build offers transparent quotes and can help optimise your budget without compromising on quality.

Not always. Many extensions fall under Permitted Development Rights, meaning no planning permission is needed—if you meet size and design limits. Rear extensions up to 6 metres (or 8 for detached homes) often qualify. But exceptions apply in conservation areas, flats, or if your home has been extended before. Always check with your local planning authority.

Yes! Unlike many kitchen fitting companies, we’re a fully qualified construction firm. That means we can take on structural alterations such as removing load-bearing walls, installing steel beams, or extending the kitchen into an open-plan living space. We’ll also ensure all works meet Building Regulations and safety standards, and can liaise with building control if needed.

The best way to begin is with a free, no-obligation consultation. We’ll visit your home to understand your goals, take measurements, and talk through design ideas. After that, we’ll provide a detailed quote and outline the steps involved so you know exactly what to expect from start to finish. There’s no pressure—just expert advice and support to help you plan confidently.

For most internal kitchen renovations, planning permission isn’t required. However, if the project involves structural changes, extensions, or your property is listed or in a conservation area, you may need approval. We’ll advise you on any permissions required and help you navigate the process so there are no surprises.

Not usually. While your kitchen will be out of action during the work, we do everything we can to reduce disruption. We’ll set expectations early, keep the space clean and safe, and ensure good communication throughout. Some clients choose to set up a temporary kitchen space with essentials like a microwave and kettle to make the process more manageable.

Yes, we can handle everything from start to finish, or just the fitting if you've already purchased a kitchen. Whether you've chosen a kitchen from a national supplier like Howdens, Magnet, or IKEA, or you'd prefer a completely bespoke design, we're happy to fit to your specifications or guide you through sourcing high-quality materials that suit your budget and vision.

Yes. Building regulations approval is required for most garage conversions. This ensures the new space is safe, energy efficient, and structurally sound. Your builder or architect should help you make sure everything complies – from insulation and electrics to ventilation and fire safety. Feel free to contact us to discuss your project.

For straightforward conversions, many builders can manage the whole process – including design, building regs, and construction. However, if you're doing something more bespoke or want help planning the space, hiring an architect or designer can be a smart move.

You can, but it’s more complex. You’ll likely need planning permission, and the space will need to meet more stringent building regulations. Things like soundproofing, private access, a kitchen, and a bathroom all need to be considered. It’s best to speak with a professional early on if this is your goal.

Yes, all of our work, including garage conversions, are backed by a workmanship guarantee, ensuring quality and durability. We also ensure that all work meets current building regulations.

We use high-quality insulation materials to ensure energy efficiency and year-round comfort. This includes rigid foam insulation, mineral wool, and breathable membranes where needed.

In most cases, yes. Converting a garage into usable living space can add significant value to your home – especially if you're adding a bedroom, home office, or playroom. Buyers are often more attracted to extra living space than an unused garage.

Costs vary depending on the size of your garage and what you're converting it into. On average, expect to pay between £10,000 and £25,000. A basic conversion will be at the lower end, while something like a bedroom with an en-suite or a home office with extra insulation will cost more.

Absolutely. If you'd like to keep some storage space, your builder can design a partitioned area that's sectioned off from the converted room. This way, you get the best of both worlds – extra living space without losing all your storage. At Kingdom Design & Build, we can help you with both the design and build of your project.

Yes, we offer a full design and build service for garage conversions in Oxford. From initial concepts to architectural plans, we ensure your garage conversion project is designed for both style and practicality.

Most standard single garage conversions take around 2 to 4 weeks, depending on the size and complexity of the job. If you're adding a bathroom, moving walls, or upgrading electrics, it could take a bit longer. A good builder will give you a clear timeline before starting work.

In many cases, you don't need planning permission to convert your garage, especially if the work is internal and doesn't change the structure of the building. However, if you're turning a detached garage into a living space or changing the use of the building significantly, you may need permission. It's always wise to check with your local council’s planning department to be sure.
