Open Space - Frequently asked questions and useful links

Do I need to acquire plans to start my loft conversion or house extension project?

Yes, you do need a set of drawings. But if you’re not too sure where to start we have long-established relationships with highly experienced architects and structural engineers.

How much do plans cost?

The average cost of ‘working’ drawings is £1500. These are also required in order for us to produce an estimate. We can arrange for the plans to be drawn up and we’ll deduct the cost from the job total - should you decide to use us to complete the project.

Do I need planning permission?

In most cases you don’t need to obtain planning permission. The majority of loft conversions and house extensions are under what’s known as 'permitted development'.

You might need planning permission if you live in a conservation area or the space required exceeds ‘allowed volume’. To get the full lowdown on this stage of the building process we can happily arrange a meeting with our architect or take a look at The Planning Portal.

Can I see some of your past projects?

No problem at all.

We have many satisfied customers who are more than happy to show potential clients some of the amazing things we have achieved for them.

Is your work guaranteed?

Yes it is. We give a full written guarantee, plus the local authority will issue a ‘certificate of completion’ which confirms that your new space has been built to a high standard and meets all safety regulations.

What areas do you cover?

We cover most of London, including: Barnes, Battersea, Chiswick, Clapham, Fulham, Hammersmith, Kensington, Mortlake, Putney, Richmond, Roehampton, Sheen, St Margarets, Wandsworth, Wimbledon, all of south west London, west London, all of Middlesex and Surrey.

What do I need to look for when comparing quotations?

  • The quotation must be fully broken-down and itemised
  • All stages of the project must be clearly defined
  • Details of the required materials should be included
  • Assurance that materials meet building regulations
