Smooth communication and a great sounding board for solutions. We did an extension and they were meticulous with the details. Highly recommended.

DNA Kalmar-Öland Bygg is a local two-person team helping homeowners bring ideas to life at home — from new builds and extensions to renovations that make everyday life a little better. We are based on Öland with Borgholm and Mörbylånga as our core area, but also take jobs in the Kalmar area.
Whether it’s a new roof, cladding and facade work, better insulation, new windows and doors, or an interior renovation in the kitchen, bathroom, hallway or basement, we like clear solutions and a neat final result.
Further down the page you’ll find photos from previous projects — perfect if you want inspiration and examples of results and details.
We like building projects to feel simple: clear guidance, local knowledge, and a setup that fits you. Here are four things that usually make a difference.

Whether you’re planning an extension, renovating at home, or building new, we help you bring the whole project together. We take on both smaller improvements and larger projects — always with a focus on a clean, durable result.
We handle much of what homeowners often need: roofs, cladding and facades, insulation, windows and doors, plus renovations in kitchens, bathrooms, hallways and basements. And when you want more space, we’re happy to help with a deck, garage or storage.

We are based on Öland and often work in both Borgholm and Mörbylånga municipalities. We also take projects in the Kalmar area when it fits.
The coast and island life have their own conditions — weather, wind, material choices and details that need to be right from the start. We have lived and worked in Kalmar and now operate on Öland, which means we know the area and can help you choose solutions that last over time.

ROT tax deduction is often a natural part of home renovation. We keep it simple and clear — no hassle.
Pricing is tailored to what feels right for you: a clear fixed quote, or hourly work when that’s most transparent.

We want it to be easy to get started. That’s why we offer a free home visit on Öland — so you can show us on site, ask questions and get the right direction early.
We review the conditions, talk through your ideas, and suggest a good next step. A calm first meeting that usually makes the rest of the project easier and more secure.
Three simple steps — from first contact to done.

We come out and review the conditions on site. You can share ideas, ask questions, and get a clear view of the next step.

You choose what feels most secure: a fixed quote or hourly. We talk through the options and land on a setup that fits you.

When we start, we build with clear communication along the way. We check in continuously so everything turns out as you planned.

We mainly help homeowners with both smaller carpentry jobs and larger building projects — from first idea to finished result. This can include new builds, extensions and renovations, as well as improvements that make the home more practical, attractive and energy‑efficient.
Common work includes roof replacement, cladding and facade work, insulation, windows and doors, plus renovations in kitchens, bathrooms, hallways and basements. We also build decks/terraces and can help with garages or storage when you need more space.
We are based on Öland and the island is our primary area. That lets us stay close, flexible and well‑versed in local conditions when you build or renovate.
We often work in the Borgholm and Mörbylånga municipalities, and also take projects in Kalmar municipality and nearby areas when the project fits. Not sure if you’re within a reasonable distance? Get in touch and we’ll tell you.
First we talk briefly about what you want to do and what matters most to you: time, budget, function or finish. We often start with a site visit to assess conditions and ask the right questions early.
Then we agree on a setup (fixed quote or hourly) and plan the work in clear steps. During the build we check in continuously, so you stay in control and can make good decisions if choices come up along the way.
Yes — we offer free home visits on Öland. It’s often the quickest way to get the right picture of the project, because details like measurements, surfaces, angles and existing structures affect both plan and price.
On site we can also talk through options, material choices and smart solutions. The easiest way to book is to call or use the form — just tell us what you want to do and where on Öland you live.
A fixed quote suits you if you want a clear setup with defined scope, making budgeting easier. It works best when the scope is clear and you want boundaries from the start.
Hourly pricing suits you if you want flexibility, especially in renovations where you may discover things after opening up (e.g., in joists, behind cladding or at connections). Then a clear estimate plus ongoing follow‑ups can be both transparent and smooth.
ROT is common in building and renovation projects for homeowners. The basic idea is that the tax deduction usually applies to labor costs (not materials), which often makes the project more cost‑effective.
The important part is clarity from the start: which tasks count as labor and how it’s specified. We help keep the setup clear and tidy so ROT is handled smoothly.
Absolutely. Many people reach out early — “we’re thinking about…” — and that’s often a great start. We can help you think through goals, function and priorities before you lock in a solution.
We usually discuss technical conditions like substrates, load‑bearing capacity and moisture‑sensitive parts, as well as how to create a good overall plan and execution. It’s often easier and more cost‑effective when the right decisions are made early.
It depends on what you plan to do and where the property is located. Extensions, certain facade changes and accessory buildings may require a permit or notification, while other measures can be permit‑free.
A good first step is to compare your project against the municipality’s guidelines and detailed plan. We can help you sort out what’s usually relevant to check so you avoid building on the wrong premises.
Coastal environments can mean more wind load, more moisture exposure and sometimes more salt in the air, which puts higher demands on details. Material choices and workmanship make a big difference for longevity, maintenance and how the structure performs over time.
Pro details often include proper ventilation in the construction, well‑thought‑out connections and metalwork, and fasteners that withstand the environment (the right corrosion class where needed). Details are often what decide whether it lasts for many years.
We like things to be orderly. That means clear check‑ins, doing the right steps in the right order and not rushing critical parts.
In practice, it often means checking substrates and measurements, ensuring good connections and being extra careful in moisture‑sensitive areas. Ongoing dialogue is important — so you know what’s happening, when and why.
Time depends on scope, conditions and whether the project requires waiting times, such as material deliveries, weather or decisions along the way. Smaller jobs can go quickly, while renovations and extensions often have more steps and dependencies.
The best approach is a short conversation about your project, so we can give a reasonable sense of effort and a rough timeline. We’d rather be clear early than promise something that won’t hold.
Yes — we’re happy to help choose solutions that fit the house, the location and your ambition. Materials are not just about looks, but also function, maintenance, moisture resistance and how details meet.
We can explain the differences between options in plain language, such as what affects lifespan, stability and feel. The goal is for you to understand what you’re paying for and feel confident in your choice.
Construction always creates waste and offcuts, and it needs to be handled smartly. The key is a plan for sorting, removal and keeping the work area safe and reasonably tidy throughout the job.
We discuss this as part of the setup so it’s clear what’s included and what may need to be handled in a specific way depending on the project and location.
Some projects require more than carpentry, such as electrical, plumbing or metal details. In those cases it’s common to coordinate with the right specialists so the whole job is completed correctly.
For you as a client, that means a smooth overall process: the right tasks in the right order, clear boundaries between steps and good communication. We bring this up early if your project includes those parts.
The fastest way is to call or send a request through the form. Briefly describe what you want to do and where you live (Öland or the Kalmar area) so it’s easier to give a good first answer.
We get back as soon as we can. If you can, mention whether it’s for example a roof replacement, extension or renovation, and any preferred timeframe — then we can guide you straight to the next step.
