QUALITY SELF BUILDS FOR OLNEY RESIDENTS
If you have a plot of land in Olney or you are thinking about buying one then you probably know how difficult the process can be. Building your own home is a massive dream but it comes with a lot of stress if you don't have the right team behind you. At Astrum Construction we take on the heavy lifting so you can actually enjoy seeing the house go up. We don't overcomplicate or make big promises we can't keep because a self build Olney project is a long term commitment for everyone involved. It helps to have a builder who is honest about the costs and the timelines right from the start. We work with you to turn those architectural drawings into a real building that fits the local character of the town.


Managing your self build Olney project
The biggest worry for most people is how to manage all the different trades and keep the budget under control. We handle the whole process from digging the foundations to the final roof tiles and the internal plumbing. A self build Olney needs a lot of coordination with the local building inspectors and utility companies to make sure everything is legal and safe. Our team is used to working on tight sites or in conservation areas where access might be a bit tricky. We don't believe in hiding costs within the bill. If we find a problem with the ground conditions or a delay with materials we tell you straight away so we can find a fix together.

Building a home that lasts
We focus on quality materials because your new home should be built to last for generations. In Olney you might want a house made of traditional stone or maybe something more modern with high energy efficiency. We can install air source heat pumps and underfloor heating to make sure your self build Olney is cheap to run and warm in the winter. We are members of the Federation of Master Builders which means our work has to stay at a high standard. It isn't just about making the house look good on the outside; it is about making sure the structural work is solid. We stay on site until the job is finished and we don't jump between different projects while yours is half done.

Frequently Asked Questions
Are you fully insured?
Yes, Astrum Construction carries full public liability insurance on every project we undertake. We are also proud members of the Federation of Master Builders, giving you additional peace of mind that we operate to a recognised code of conduct and high professional standards.
How do I get a quote?
Simply get in touch via our contact page or give us a call and we will arrange a no-obligation visit to discuss your project. We will talk through your ideas, assess the property, and provide a clear, itemised quote with no hidden costs.
How long will my project take?
Timescales vary depending on the size and complexity of the work. A loft conversion typically takes 6–8 weeks, while a full extension can take 3–5 months. We will always give you a realistic programme at the quoting stage and keep you regularly updated throughout the build.
Do you handle planning permission?
We can advise on whether your project requires planning permission and guide you through what is involved. Many extensions and conversions fall under permitted development, but where a full application is needed we can recommend trusted local planning consultants to support you through the process.
