Do you offer free quotes?
Yes — we provide free, no-obligation quotes for every project. Call us on 07772 336 809 or email [email protected] and we’ll arrange a visit to discuss what you have in mind.
What types of projects do you take on?
Our specialisms are garage conversions, loft conversions, and barn conversions. We also undertake general building work including extensions, kitchen and bathroom installations, and full house renovations. If you’re not sure whether your project fits, just ask.
How long does a typical conversion take?
Timescales depend on scope, finish, and any planning requirements. As a rough guide: garage conversions typically run 4–6 weeks, loft conversions 6–10 weeks, and barn conversions 10–16 weeks. We’ll give you a clear, honest timeline as part of your quote.
Do I need planning permission?
Many garage and loft conversions can be carried out under permitted development rights, but barn conversions, larger extensions, and properties in conservation areas usually require formal planning permission. We’ll advise on what your project needs and handle planning and building regulations applications on your behalf.
Are you fully insured?
Yes. Astro Building Services (Wales) Limited carries full public liability and contractor insurance on every project, giving you peace of mind from day one.
Can I stay in my home during the work?
For most conversions and renovations, yes. We plan the work in stages to keep disruption to your daily life as minimal as possible, and we’ll talk you through what to expect at each stage as part of the quote.
How do I get started?
Just get in touch. Call 07772 336 809 or email [email protected] with a few details about your project and we’ll arrange a free site visit to walk you through the options.
