There are many, many details that we need to know about you and your site. However all we need enitially is a 15 minute phone conversation to establish, how we can help. People buy sloping sites because of the views, they are looking for something different, and the fact that sloping sites are cheaper. Usually the steeper the cheaper. However most buyers are put off by not having answers to these 5 questions.


  1. How do I build on a slope?
  2. Who’s going to design it?
  3. Who’s going to build it?
  4. What’s it going to look like?
  5. How much is it going to cost?

First question:
Is your site on the low side
or the high side of the roadway?

Designing a house on the high side is very straight forward. The driveway simply comes up from the roadway to the carport which is excavated under the living area. Entry into the house is usually from a set of stairs coming up onto the deck, and the entry into house is usually from the deck.

Building on the low side of the road is a little more involved as the entry to the house is on the road, at the rear of the house. Entry into the house is covered later in this section as well as alternative vehicle access and carport positioning.

Driveways and carports

Driveways and carports

One of the most critical factors in designing a house for a sloping site is vehicle accommodation. It’s not much use having a beautifully designed home if there’s nowhere to put your vehicles. Driveways and garage do, unfortunately, eat into your house budget.
Driveways and carports

Land sloping upwards from the roadway

Vehicle access to the carport would be straight up off the roadway and up under the house. Stairs would usually go from the leveled concreted carport pad to the house deck area or onto a separate entry landing. The living room floor therefor becomes the carport roof.

Land sloping with the roadway

A flattened are would be excavated under the house. It would be a easy drive off the road and under the house.

Land sloping downwards from the roadway

Vehicle access to the carport would be straight up off the roadway and up under the house. Stairs would usually go from the leveled concreted carport pad to the house deck area or onto a separate entry landing. The living room floor therefor becomes the carport roof.
Driveways and carports

Separate free standing carport to the front of the site

Building a free standing carport or garage is another option for sites on the low side of the roadway. The house could be positioned further down the site to allow a free standing carpor to be constructed close to the roadway.

Entry hallway for homes

Entry hallway for homes built on the low side of the roadway

The living and deck areas of the house will obviously face the views, down the slope. Which means the entry into the house will be at the back of the house. (Street side) This entry way can be easily incorporated into any of our designs

We usually incorporate an entry portico and landing to enhance the appearances of the house from the street.
HIA Australia

Roscher have 2 types of service


Design and construction service

We design the homes and we have appointed 4 HIA accredited builders to construct our homes in these areas.
Northern NSW, Gold Coast, Brisbane and Toowoomba.
Our builders have calculated the exact construction base price of all our designs. It's Then a simple matter for the builder to inspact your site and price the changes you may want to the design and calulate the site cost and produce an accurate all up price.

Design only service throughout Australia

This service is for clients wanting to build outside our 4 designated areas.
Initially we can calculate a ball park figure for our designs based on out construction price in Brisbane. We then discuss your requirements with a specialised pole home HIA builder in your local area who will inspect your site. An accurate construction figure can then be produced.


What we do


We analyze the slope of the site from your contour plan and photographs you supply and the builder carries out a site inspection. We take into consideration the local council requirements; boundary setbacks, developers covenants and discuss the merits of each one of our designs with you and the changes you may want to make. We supply rough concept floor plans of the house including all the alterations you have requested together with your site plan with driveway and house positions.

Once you're happy with the above, and of cause with the contact price we require $3,250 to prepare Cad architectural working drawings which will include site plans, floor plans, 4 elevations, section plan, ground level plan and a 3D prospective drawing.

The 3D drawing will illustrate how the house will look on the site, when completed. These plans will be fully detailed and ready for council approval. The $3,250 forms part of the contract price
