A conservatory can add real value to your home, a recent study by Ideal Home Magazine says:

Conservatory Design Questions and answers:

Will I need planning permission for my conservatory?

We will perform a full assessment if you need planning permission once we have spoken to you about your property and proposed conservatory.

We will then provide you with a written breakdown of all application and design costs.

The Planning Portal is a good website to check and gather info for if you need planning approval. We would always advise that if you are unsure if you need planning permission, that you contact us for advice.

Why are your fees less than I have been quoted by a local Architect?

We try to be as efficient as possible with our work. We understand that you need the permissions to complete your project as cheaply as possible. We only undertake small projects and extensions and are able to give our clients 100% of our time and commitment. You may find the other architects and surveyors are tackling large projects and your small project is a small part of their overall workload.

Do you fill out the planning permission application forms and submit the application to the local authority?

We fill out all forms and submit your design to your local authority. The planning forms can be quite complicated and we would not leave these to a client to fill out themselves. A mistake can prove costly in terms of time and anyone who has dealt with a planning department knows it may take up to a month for the council to write you a letter explaining any problems with your application.

I'm building close to my neighbours property and we have a drain cover located below where we want our new conservatory. Do you give advice on that?

Yes. We are able to discuss on site issues with conservatory foundations and drainage running below your new conservatory. We are able to place a conservatory foundation and drainage design on our plans. This will help you when choosing a company / contractor to build your new conservatory.

Do you give advice on how to achieve planning permission for our conservatory?

Yes, we will provide free advice on how best to achieve the planning approval for your conservatory. We can spot planning problems that conservatory suppliers do not inform their clients about as this is the area we specialise in. We will always advise the best way around any problems and inform you on alternative solutions that get us over an issue. We all want your conservatory planning application to be passed at the first attempt.

Do you charge for amendments to the plans if the local authority want our conservatory design changing?

No. Local authority amendments are dealt with free of charge.

Can we place our conservatory up against a neighbours wall?

If your neighbour is in agreement and the wall is on the boundary, then we can issue you with Party Wall Agreement forms for you to agree with your attached neighbour. We also provide you with a set of plans for the Party Wall Agreement. We are also able to offer advice on site about this subject,

Can you design a retrospective planning permission application a conservatory?

Yes, this is where a conservatory has been built and it has been found that planning permission should have been sought prior to the installation of the conservatory. We have dealt with many retrospective applications over the years and have a good success rate. Please contact us to enquire if we can help you with this type of application.

How many sets of plans will I receive?

We provide 2 sets of paper plans and PDF set to the homeowner so they can print their own plans off should they wish.

We submit our planning applications to the planning portal to speed the process up. Using the planning portal saves posting the application to the council and often saves several days.

Can you provide an estimate for the price of our conservatory.

We would recommend you use a Conservatory Quotation site to find out prices for your conservatory.
