Good questions, straight answers
What’s included in every price?
Premium timber construction, timber shiplap cladding, an EPDM rubber roof, anthracite uPVC French doors, two full-height windows, PVC fascias and soffits, a breathable membrane, delivery, installation by our own team and VAT. Insulation and plastering, flooring, electrics, composite cladding and decorating are optional, and priced as you choose them.
Is the price fixed?
Your price comes from LouMil’s current calculator and includes VAT. We confirm your specification, access and base on a short consultation call before you order, and nothing is added later.
Do I need a base?
A level concrete, paved or compacted hardcore base is ideal. If you don’t have one, choose ground screws: 1m galvanised screws, fully compliant, with no concrete.
Do I need planning permission?
Most of our builds fall under permitted development, but it depends on size, height and location. We’ll talk it through on your consultation call.
Is decorating included?
Decorating is an optional service carried out the week after install, once the plaster has dried, and invoiced separately on the day. Without it, your room is handed over plaster-finished, ready for your own decorator.
Do you install nationwide?
Yes. We deliver and install across the UK with our own installation teams.
